Feature Suggestions for Glynce Pro
in progress
H
Has
I’m using Glynce Pro with my FreeStyle Libre 2 Plus, and I have a few suggestions that I think would make the app even better.
- Automatic glucose updates without LibreLink running in the background
Other apps, such as FLwatch, can retrieve glucose readings directly from compatible Libre 2 sensors without needing the Libre app running in the background. However, Glynce currently seems to depend on LibreLink remaining open.
Since we pay for Glynce Pro, would it be possible to find a way for glucose readings to continue updating automatically without requiring another app to run in the background? I understand that this may depend on Abbott’s system and the sensor being used, but it would be a great improvement if technically possible.
- Insulin tracking and an insulin activity graph
It would be great to have a feature that lets us see which insulin we inject it, then display its expected activity on the glucose graph.
For example, I use NovoRapid, a rapid-acting insulin. The graph could show when the insulin is expected to start working, when its effect is strongest, and approximately when its activity ends. This would help users understand how their insulin doses relate to their glucose levels throughout the day.
Ideally, users could select their insulin type, as different insulins have different activity profiles.
- Customisable glucose update intervals
Could you add a setting that lets users choose how frequently they want their glucose readings to refresh, with options such as:
* Every 1 minute
* Every 5 minutes
* Every 10 minutes
* Every 15 minutes and so on…
This would allow users to choose their preferred update frequency, depending on their needs and device battery life. Of course, the available intervals would need to respect the sensor’s actual reading frequency and any technical limitations.
- Customisable Apple Watch app appearance
I’d like to be able to customise the appearance of the Glynce app and its complications on my Apple Watch. Currently, the display appears white, and I’d prefer to have coloured elements to make glucose readings and trends easier to distinguish at a glance.
For example, customisable colours for glucose values, trend arrows and graphs would make the watch interface more useful and visually appealing.
- Customisable Graph Time Range Across All Devices
I would like to suggest adding a setting that allows users to choose how many hours of glucose data they want to see on their graphs, with options such as:
* 3 hours
* 6 hours
* 12 hours
* 24 hours
Currently, the time ranges differ depending on where you view the graph. For example, the iPhone Home Screen widget shows 6 hours, the Lock Screen shows 3 hours, and the Apple Watch shows 6 hours.
It would be much more convenient if we could choose one preferred time range and have it applied consistently across all devices and widgets. Ideally, users should be able to select up to 24 hours so they can review their glucose trends throughout the entire day.
This would make it easier to compare glucose patterns across the iPhone, Lock Screen and Apple Watch without having to interpret different time ranges on each device.
Please consider adding a universal graph time-range setting that synchronises the selected duration across all supported displays, with 24 hours as the maximum option.
I believe these improvements would make Glynce Pro more convenient, informative and customisable, particularly for people who rely on continuous glucose monitoring every day.

Has Critical alerts, repeating alerts, low vs very low
Glynce doesn’t send glucose alerts at the moment, so there’s nothing to set yet. If I add them later, settings like these are worth looking at. Critical alerts (the ones that break through silent mode) also need special permission from Apple, which they mostly give to certified medical apps. For now, the Libre app’s alarms are the ones to rely on.
There’s also a privacy side. Your glucose data stays on your phone. To alert you while the app is closed, I’d have to store your Libre login and readings on a server, which I’ve chosen not to do.
Water
Staying hydrated in general is a good idea. But water doesn’t bring a high down quickly, and it doesn’t make carbs work faster during a low. Fast-acting carbs like juice or glucose tabs work on their own. If you’re treating a low, follow the plan from your care team.
CarPlay
iOS decides how big the CarPlay card is, so I can’t make it bigger. For updates, turn on Faster updates via Bluetooth (Settings → CGM). Glynce then listens for your Libre sensor directly, so new readings show up much sooner on CarPlay, your widgets and the Watch. The setup guide on that screen walks you through it. I’ll also add more chart options, like choosing the time range.
Things Glynce already does
Other days: tap the calendar button at the top of Home to open any day.
Daily totals: Settings → Logbook shows each day with a Day summary (carbs, calories, insulin, water), and you can use the arrows to move between days. Splitting fast and long acting insulin there is on my list.
Medication reminders: create a reminder for your tablet and turn on “Ask if done”. You get Done / Not yet on your Watch, and it shows on your chart and timeline.
Drinks: Describe and Snap work for drinks too, just type or photograph them like food.
Everything else you sent is on my list: the Watch graph times, clearer timeline entries, and more. I also just fixed the meal category bug and the Save button you reported. Thanks again, this kind of feedback makes the app better!

Sem
Has Thanks for sending these, it really helps to see what you mean.
Your screenshots shows a few things I’ve decided not to do in Glynce. I want to explain why:
Predicting lows (“heads-up before the low”)
Rules in the EU (and the US) treat an app differently once it tries to predict where your glucose is going, or tells you what to do about it. At that point the app counts as a medical device. That means certification, clinical testing, and a quality system checked by an outside body. Glynce isn’t certified, so it shows you your numbers and your trend but doesn’t forecast them. A forecast can also be wrong: a warning that comes too late, or not at all, is dangerous if you’ve started relying on it.
For a warning, the FreeStyle Libre app’s own alarms are the safe choice. It has a Low Glucose alarm you can switch on and set to your own level, and it keeps working next to Glynce. If you want more warning, ask your care team whether setting the low alarm a bit higher makes sense for you.
“Eat this snack when you’re low”
Same reason: telling you what or how much to eat for a low is treatment advice. That depends on you, your insulin and what your care team has told you, so it isn’t something the app should decide. You can save your go-to low snacks in My Foods, so logging one takes a tap. Glynce just won’t tell you when to eat it.

Hi!
Thank you so much for this. It’s clear you’ve really thought about how you use Glynce every day, and that’s exactly the kind of feedback that helps us most.
Connecting directly to the sensor
I completely understand why you’d want this. Not depending on LibreLink would make things simpler and more reliable. Unfortunately, the Libre 2 Plus only shares its readings with Abbott’s own app, so we can’t safely read them ourselves. Apps that connect directly have to work around Abbott’s protection, and we can’t do that in an App Store app that follows medical device rules. I’m sorry I can’t give you better news here.
What we’ve done instead is “Faster updates via Bluetooth”, which is in the latest version. It uses your sensor’s Bluetooth signal to fetch new readings as soon as LibreLink has them, so your widgets, Watch and Live Activity stay much closer to real time. If you haven’t switched it on yet, you’ll find it in Settings.
Update interval
With Faster updates, readings from your Libre come in about once a minute, which is as often as the sensor shares them. I’ll add a setting so you can choose the interval that suits you, for example every 5, 10 or 15 minutes if you’d rather save some battery.
Apple Watch colours
You’re right, the complications only show in white for now. Colour is something I’m actively working on, so glucose values, trend arrows and the graph will soon be easier to tell apart at a glance. Thanks for flagging it, it’s good to know it matters to you.
Insulin activity on the graph
I love this idea. Seeing when NovoRapid starts working, peaks and wears off, right next to your glucose, would make the graph so much more useful. I’ve added it to our list.
One graph range everywhere
Great point. The different time ranges across the widgets and the Watch aren’t ideal. For now, you can set the Home Screen widget to 1, 3 or 6 hours by long-pressing it and choosing Edit Widget. A single setting that applies everywhere is now on our list too.
Thanks again for taking the time to write this, and for supporting Glynce Plus. If anything else comes up, just reply here.

Sem Thank you for your quick reply! I really appreciate it.
I have another suggestion that I think could be really useful for Glynce Pro
- Medication and Insulin Reminders with an Interactive Tick List
I would love to see a medication reminder feature that works as both a reminder and a tick list, rather than simply sending a notification that opens the app.
For example, if I schedule 20 units of Tresiba insulin, the notification on my iPhone Lock Screen could display:
Time to take your Tresiba insulin and what I would have it called:
💉Slow acting - Tresiba - 20 units
✅ Taken ❌ Not taken yet
When the notification appears, I should be able to select whether I have taken my medication or insulin directly from the notification, without just having to open Glynce app and not actually saying if you’ve taken it or not.
H
Has
How I would like it to work:
1 - Mark as taken: When I press the tick, the medication is marked as completed, and the time and dose are recorded in my timeline. For insulin, it would also be added to my insulin log and graph, showing when I took it.
2 - Mark as not taken yet: If I press the cross, the app could ask whether I want another reminder in 5, 10, 15 or 20 minutes.
3 - Automatic follow-up reminders: If I haven’t responded to the notification, Glynce could send another reminder after a customisable interval, until I confirm whether I have taken it or dismiss the reminder.
4 - Medication and tablet tracking: Users could add other medications, such as antibiotics or daily tablets, with their own doses and schedules.
H
Has
5 - Completed medication timeline: The timeline could show which medications and insulin doses have been completed, are still awaiting confirmation, or were skipped.
6 - Daily tick list: Inside the app, users could see a checklist of all their scheduled medications and insulin doses for the day, making it easier to remember what they have and haven’t taken.
7 - Easy to press buttons to prevent mistakes: Please make sure the ✅
Taken
and ❌ Not taken yet
buttons have enough space between them and are large enough to press comfortably on both the iPhone Lock Screen and Apple Watch.The buttons should be clearly separated so users don’t accidentally press the wrong one, especially when responding quickly to a notification or using a small watch screen. It would be helpful to have a confirmation option if someone accidentally marks a dose as taken.
Since this feature involves insulin and medication, preventing accidental taps is particularly important. The design should prioritise accuracy, accessibility and ease of use.
8 - Dose Correction and Medication History: Please also include an option to correct a dose that has been accidentally marked as taken or not taken. Users should be able to amend the status and correct the recorded time if necessary.
It would also be helpful to have a medication history showing when each dose was scheduled, when it was marked as taken, and whether its status was later corrected. This history should retain the original entry alongside any changes, so users can keep an accurate record of their medication.
This is particularly important for insulin, as accidentally marking a dose as taken could lead to confusion about whether an injection has actually been administered.
The aim is to make the medication tracker reliable, easy to use and safe, while giving users a clear record of what they have and haven’t taken.
H
Has
An important detail: Marking a dose as taken should record the actual confirmation time, while allowing users to correct it if necessary. If a reminder is missed or marked as not taken, the app should never automatically assume the dose was taken.
This would be especially helpful for people who sometimes forget whether they have already injected their insulin or taken their tablets. Receiving a notification is not the same as actually completing the task, so having a record of completed doses would provide much greater peace of mind.
Ideally, this feature would work directly from iPhone Lock Screen notifications and Apple Watch notifications, with the completed status synchronised across all devices.
Thanks

Sem
Just to clarify regarding the update interval suggestion: please keep the existing 1-minute update option and add the other options alongside it, rather than replacing or removing it.
The available options should be:
* Every 1 minute
* Every 5 minutes
* Every 10 minutes
* Every 15 minutes
This way, users can choose their preferred update interval, while those who want the fastest possible updates can still select every 1 minute.
Thank you!
Update interval
With Faster updates, readings from your Libre come in about once a minute, which is as often as the sensor shares them. I’ll add a setting so you can choose the interval that suits you, for example every 5, 10 or 15 minutes if you’d rather save some battery.

Notifications
Maybe you could add a notification for when Glynce stops receiving glucose readings or when LibreLink has been closed, so we know it’s not working and can try to fix it. We could get an alert telling us to check the connection and reopen LibreLink if needed.
H

Fingerprick Readings:
Sometimes we check our glucose using a fingerprick. Could you add an option to manually enter the reading, or ideally allow automatic syncing from devices such as Accu-Chek? I use the mySugr app, which automatically receives readings from my Accu-Chek device, so it would be great if Glynce could do something similar.
Sensor Countdown and Notifications:
Could you also show how much day is left before our Libre sensor expires and needs changing? I know this information is available in LibreLink, but having it displayed in Glynce would be more convenient. It would also be helpful if Glynce could notify us when the sensor is about to expire or if it stops working, rather than relying only on LibreLink notifications.
Sem
Hi Has,
You’re very welcome, and thank you so much for all of this. You’ve clearly thought it through carefully, and it’s genuinely helpful.
Medication reminders and tick list
I really like this one. A reminder that only opens the app isn’t much help when you’re busy. Being able to tick off your Tresiba right from the Lock Screen is exactly how it should work.
I’m going to build it the way you describe. You’ll be able to set up a reminder with the insulin type, name and dose, like “Slow acting, Tresiba, 20 units”. When it goes off, press and hold the notification and tap “Taken” (it works from your Apple Watch too), and Glynce logs the dose in your timeline and insulin graph without opening the app. If you tap “Not taken yet”, Glynce will remind you again a little later, so a dose doesn’t slip through.
I especially agree that a dose should never be counted as taken unless you confirm it, and that corrections should keep the original entry, so there’s never any doubt about whether you’ve injected. I’ll start with the insulin reminder, then build towards the daily checklist and history you describe. Other medications like tablets are a great idea too, and I’ve added them to my list.
Update interval
Good point, and yes, every 1 minute will stay. The setting will offer 1, 5, 10 and 15 minutes, so you can pick what suits you.
Alert when readings stop
Great idea, and this one is very doable. Glynce could notify you when no new reading has come in for a while, so you know to check LibreLink.
Fingerprick readings
You can already add a fingerprick reading in Glynce with the + icon. For Accu-Chek, if you turn on Apple Health syncing in mySugr, Glynce may be able to pick up those readings automatically. I’ll look into it.
Sensor countdown
Also a great suggestion. Seeing how many days your sensor has left, with a reminder before it expires, would be really handy. I’ll look into whether I can get this from LibreLink.
I’m building Glynce on my own, so I can’t do all of this at once, but every idea is on my list. Thanks again, and keep them coming!

Thank you for replying really quick
Honestly, it’s a great app, and I’m really happy with it. I’m just suggesting a few ideas. I can imagine how much work goes into developing and maintaining an app like this all by yourself, so I really appreciate all the effort you’re putting into it. Keep up the great work!
Apple Watch Compatibility:
I have an Apple Watch Ultra 2, but the app says it requires watchOS 11. Is it possible to make it compatible with earlier watchOS versions if technically possible? Also, when I press refresh on my watch, it opens the app instead of refreshing the glucose reading. Could this be fixed so it refreshes directly? This is especially important if we want to use features like the medication checklist on the watch.
Apple Watch Without the iPhone Nearby:
Since we have Glynce installed on our Apple Watch, is it possible for it to work independently without needing the iPhone nearby? It would be great if we could still access our glucose readings and other features when we’re away from our phone.
Editable Timeline:
Could you make the timeline fully editable? At the moment, if I enter the wrong carbohydrate amount, I have to delete the entry and add it again. It would be much easier if we could edit everything directly, including carbohydrates, insulin doses and other entries, rather than only being able to change the serving size.
Fingerprick Readings and Apple Health Sync:
There currently isn’t an option to add fingerprick readings (see attached image). I also have Apple Health synced with my mySugr app and Accu-Chek glucose meter, but those readings don’t appear in Glynce.
For the future, it would be great to have a small fingerprick icon showing when a fingerprick has been done, with the reading recorded in the timeline and logbook alongside the sensor readings. This would make it much easier to see and compare both types of readings in one place.

CarPlay Widget:
The CarPlay widget is great, but I can’t seem to change the graph’s time range or how frequently it updates. Could you add an option to customise the graph, such as showing the last 3, 6, 12 or 24 hours, and let us choose the update interval (1, 5, 10 or 15 minutes)? At the moment, the graph looks very small, so it would also be great if it could be made larger and easier to read while driving.
Add drinks:
When you click the “+” button, could you also add options for “Drinks”, “Describe food/drink” and “Snap food/drink”?
Save button not working properly:
When you use “Describe food” and click “Save” after entering the information, it sometimes takes 5–10+ seconds to save. Sometimes, you have to press and hold the “Save” button for it to work. Could this be fixed so it saves straight away with a single tap?
Wrong meal category saved:
When I select “Breakfast” or “Snacks” and save the entry, it sometimes saves it under a different category instead of the one I selected. Could you fix this so the entry is saved under the correct option?

Timeline – Improvements and New Features
- Navigate Between Previous Days:
Could you add a left and right arrow next to the Timeline heading so we can navigate between days?
- Left arrow: Go back to the previous day and view that day’s timeline.
- Right arrow: Move forward towards today, one day at a time.
- Allow us to go back as many days as we need.
It would also be helpful to display the date we’re currently viewing, so we always know which day the timeline belongs to.
- Daily Summary Under the Timeline Heading:
Could you add a small daily summary directly underneath the Timeline heading, showing the total carbohydrates and insulin recorded for the selected day?
For example, if I take 20 units of slow-release insulin, followed by 5, 6 and 2 units of rapid-acting insulin, and eat 106g of carbohydrates, the summary could look like this:
Slow-release | Rapid-acting | Carbs
20 units | 13 units | 106g
The totals should automatically update whenever I add, edit or delete an entry, and change when I navigate to a different day. It would make it much easier to see my daily totals at a glance.
H
Has
- Make the Timeline More Visually Appealing:
The timeline currently looks a little plain. Could you make it more visually appealing, with a clearer layout, better spacing and more visual distinction between different types of entries?
- Customisable Icon Colours for Different Insulin Types:
At the moment, slow-release and rapid-acting insulin use the same icon and colour, making it difficult to tell them apart quickly.
Could you allow us to customise the colours of the icons for insulin, notes, food descriptions and activities?
For example:
- Slow-release insulin: One chosen colour.
- Rapid-acting insulin: A different chosen colour.
- Breakfast, snacks and other food: Their own identifiable icons and colours.
- Notes and activities: Customisable colours as well.
This would make the timeline easier to understand at a glance, especially when reviewing insulin doses.
- Improve the Layout of Entries at Similar Times:
When multiple entries happen around the same time, could you display them vertically, one underneath another, rather than placing them side by side?
For example:
🍔 Breakfast
🩼 Slow-release insulin
💉 Rapid-acting insulin
Each entry would appear on its own line, making it easier to see what happened and in what order. If breakfast and both types of insulin are recorded at around the same time, they should still be clearly separated vertically rather than crowded together.
Overall, these changes would make the timeline more informative, easier to navigate and more personalised, while helping users understand their food, insulin and activity records more clearly.

I really like this idea, where you can put few snacks of what it is and how much carb or even just scan the barcode, and when your sugar level is dropping or low, you csn have the snack/drink what the app says to get your sugar level back up

This sounds really good, if there is a big drop coming up, you can get notified, so before it shows a arrow showing down, we can counter it before it goes to a very low sugar level, that can be hard to control or to bring back up, this sounds really great!

Glucose heading low
Now 82 v - may reach 55 mg/dL in ~15 min.
Have fast-acting carbs ready.
Nofitication - glucose going down:
I really really like this notification, where it shows what your sugar level is, and what level it can go down to, so be ready to take fast-acting carbs, so it doesn’t drop even lower.

I really do like the notificstion system where it will notify you and you pick how often should it remind you that your sugar level is still low or high, and the reminders, also how the notificstion is being recieved also when your sugar level is low, it warns you beforehand that it’s going to go right down, so you can take few carbs before it just drops down
Can litterally save a life

This is what I was talking about making timeline/logbook better, and putting in groups underneath the heading, I’ve marked it with red outline box.
Showing the total amounts you had or given yourself throughout the day
Total amounts:
- Food/drink (total carbs)
- insulin (fast and slow release)
- Medication (tablets)
- and others if you want
For the insulin, on the app, I don’t like how they merged fast and slow release insulin together, it’s better to keep them seperate, because they are 2 different insulins.

Watch: graph info & timeline.
For watch wdiget, the graph, is it possible to have time underneath the graph, showing what it was at certain times like how you have on the lockscreen for mobile 14:00, 15:00, 16:00, without showing no info
Will be great also to see what time we had food and insulin or other medication on the watch aswell like the icon, and the timeline when you click the app.
