5.0The only feedback I have is I wish I found it sooner. With Sugar Sense, I am able to see where my number is trending. The alerts when I am 90 or 80 saying I’ll be low in 20 minutes is a game changer. That has helped me stay in range more and helped me not correct too soon.

5.0It has changed the way I manage my diabetes. I use a Dexcom ONE+ sensor and this app has given me the fast rise/fall and the urgent low soon alerts. This really helps me prevent hypos and act faster than I normally could. I don’t normally write reviews but this app is certainly worth downloading.

5.0Being blind I have been looking for something very reliable and easy to use to hear my blood glucose levels. I linked my CGM and completed the step by step setup, even set up to use with Alexa. I love that every time my CGM updates I hear the update automatically without having to open my phone and navigate the screen readers. Life simplified. I am using it on my Android phone. The only thing I would like is to have options of voices that can be used.

5.0I can see my blood glucose readings on my watch and I can put a chart on my phone lock screen, meaning I can stay always up to date. In addition it will send and receive to Health, a feature I desperately wanted for the FreeStyle Libre.

5.0Life-changing! I have Sugar Sense on my phone, laptop and now on my smart watch. My CGM reading is only a glance away from wherever I look. Knowing your blood glucose throughout the day and night is the best way to fight this disease. I highly recommend Sugar Sense for all your devices.

5.0Sugar Sense makes glucose monitoring feel much easier with real-time readings, customizable alerts and a clean interface. I especially like the predictive low alerts and Care Circle, which make it reassuring to stay on top of trends and keep family informed. The free core features offer a lot of value.

5.0Such an incredible app to track health, especially sugar levels. You can create your own logbook, connect directly to Apple Health and set up reminders. Haven’t heard or seen any tracking app as credible as this.

More App Store reviews
Every written four and five star review of the iPhone app from every App Store country, quoted word for word under the reviewer's store nickname with the country and month, pulled from Apple's public review feed twice a day and never edited or typed in. The bold line is the reviewer's own title. Reviews already quoted above are not repeated. Google Play publishes no such feed, so its reviews appear in the selection above and on the store itself.

5.0This so has everything you need to manage your diabetes I had many apps because each did specific things like carb count but now I just use Sugar Sense. It has everything in one app. You should try it out.

5.0Thank you, thank you for replacing sugarmate I’ve used sugarmate for years, and a while back they just got rid of all the features that made them great. No more connecting with the Alexa. No more Siri shortcuts even. I don’t know why they would just get rid of all these great features, but I got rid of them now. I love the way you have all of these features here and so much more. This is just the best app. I am so happy I found it. So great

5.0The best app out there My wife has diabetes for over 70 years now. She has done a great job along with my help of keeping her healthy and well. We do this with a few apps over the years to watch over her sugars. This is by far the best app we have ever used. Its for me to watch over her sugars and easy for her to use in conjunction with her CGM device. Check this out, we highly recommend it.

4.0Great Customer Experience Type 1 parents who's T1D warrior uses insulin pens and a G7 : this app now has lots of cool widgets and useful safety features. They updated the app so that parents can now also add doses to the insulin log from their premium family member apps on their own phones which is so helpful. The app creator is genuinely caring and took action to help improve the app when they received feedback. Great app worth investing in for your family care circle especially in split households.

5.0Das ist super Ich nutze Sugar Sense seit vier Wochen, am Anfang hatte ich Probleme mit den Einstellungen, eine kurze Mail, und mir wurde innerhalb kürzester Zeit geholfen. Seitdem läuft alles stabil zuverlässig.. Die Anzeigen sind sehr gut verständlich und gut zu lesen. Ich kann die App nur empfehlen und nutze sie selbst ab sofort täglich.

5.0My CGM data viewer of choice As a new user of a CGM, I was keen to see the data that it would provide about my daily diabetes ups and downs;and indeed there were immediate revelations which I was able to act upon. But the way in which data was displayed in the CGM apps of the manufacturers (first Dexcom and then Libre) did seem to me to make it a bit of a chore to delve into it in a frictionless way to understand more about my diabetes. When I tried Sugar Sense I immediately felt comfortable with the data presentation. At a glance I see what's happening right now with my numbers; and when I want it, it takes one Click to see a more in-depth data view, all on-screen without having to export or print, although those functions are available too. Sugar Sense is now my first choice as a window to view my data and learn from it. Sugar Sense can connect to Libre and Dexcom and certain other CGMs (but their own link apps are needed too). It also lets you see your current glucose number at a glance by placing an optional display on the phone’s lock screen: tap the phone screen and there’s the number. I can be out walking with my phone in my pocket and have Siri read out my number whenever I ask, direct to my in-ear hearing device. Or if my Watch was not such an old model I could display it on there through Sugar Sense’s own app. It also connects to CarPlay and automatically displays my glucose number on that screen, so it is always available when I am driving. Support from the developers is first class. I have had fast comprehensive and thoughtful email responses to my queries. Most impressively, when I reported what I thought was a false or anomalous nighttime low reading, Sugar Sense was quick to drill down into the data history around this reading and established that there was no bug of false reading and explain it all to me in an enlightening way. A great app from a developer who is himself a T1 diabetic and understands the needs.

5.0Best app Sugar Sense: CGM and A1C Tracker is a convenient app for keeping health information organized in one place. The interface is clean, simple, and easy to navigate, making it straightforward to review readings and track changes over time. I like how the information is presented clearly without feeling overwhelming. It can be useful for maintaining a consistent tracking routine and staying more aware of daily health trends and progress.

The honest limits
The points people raise most often, in our own words, so nobody installs the app expecting something it does not do.
- It is a companion, not a medical device. Sugar Sense displays data from your CGM and must never be used for insulin dosing or other treatment decisions. Keep your official CGM app and its alarms on.
- It needs a cloud pathway. FreeStyle Libre readings arrive through LibreLinkUp, Dexcom readings through Dexcom Share and Nightscout readings through your own site. No internet means no new readings, and a reading can trail the sensor by a few minutes.
- The core is free, some extras are paid. Live glucose, graphs, statistics, the logbook, every alert, family following and Apple Health are free. The Apple Watch and Wear OS apps, Live Activity, AI insights, the emergency call and PDF reports are Premium. The pricing section has the full split.
- The review count is still modest. The iPhone app reached the App Store in June 2025 and the Android app reached Google Play in August 2026, so the ratings are counted in dozens, not thousands. We show the real number rather than a padded one.
Not to be confused with
The Sugar Sense on this site is a CGM app made by Sugar Sense OÜ in Tallinn, Estonia. It has no connection to any dietary supplement, pill or glycemic-support formula sold under a similar name, and none to the non-invasive glucose gadgets sold on marketplaces under a similar name. If a review you found online is about a bottle or a wristband, it is about a different product. This site, the App Store listing and the Google Play listing are the only official homes of the Sugar Sense CGM app.
