7 Best Glucose Apps in 2026, and How to Choose
Seven apps that help you understand blood sugar, from logbooks to sensor apps to AI. What each one is for, and who should skip it.
Blood sugar apps do very different jobs. Some are logbooks for people with diabetes. Some pair with a sensor. Some read your whole week. This list sorts them by job, so you can pick the one that fits.
| App | What it is | Sensor | Best for |
|---|---|---|---|
| A1C Insights | App that reads glucose, Apple Health or Health Connect, sleep, activity, food and labs | Optional | Glucose read next to sleep and food, with someone to ask |
| Lingo (Abbott) | Over-the-counter sensor and app, sold in the US | Its own, up to 14 days | Trying a sensor with its own app |
| Levels | US-focused sensor program with a membership app | Yes | People in the US who want a sensor with a membership app |
| Bevel | AI health coach app for wearable data | Its site does not mention glucose sensors | People who own wearables and want one view |
| Ultrahuman | Smart ring maker with a glucose platform | In the US, M2 Live pairs with Lingo | People who want a ring and a sensor in one ecosystem |
| Health2Sync | Diabetes management app from Taipei, Taiwan | Syncs data from more than 80 devices | People with diabetes who want a logbook and reports for a clinic |
| mySugr | Diabetes logbook app owned by Roche | Stores data from connected devices | People with diabetes who log daily |
Disclosure: A1C Insights is our app. It is first because it is ours, not because the list is neutral. Judge the rest on what each does.
How did we choose?
Each app is here because it does one of three things: logs glucose and food, reads sensor data, or explains the data. We left out apps we could not check.
One caution first. Most "in range" targets in these apps come from guidance written for people with diabetes. There is no agreed range yet for healthy people. Use any app to learn your patterns, not to label yourself.
1. A1C Insights
Brings together glucose from a sensor, Apple Health or Health Connect, sleep, activity, food you log and uploaded lab reports. Sally, the AI inside, explains your week in plain words and answers questions from your own data. Sensors are optional. Available in English, Bahasa Indonesia, Malay and Chinese.
Best for: people who want glucose read next to sleep and food, with someone to ask.
Skip if: you only want a simple logbook.
2. Lingo (Abbott)
Abbott's over-the-counter sensor and app for adults who do not have diabetes and are not on insulin. Sold in the US. One sensor lasts up to 14 days. Check Abbott's site for other countries.
Best for: trying a sensor with its own app.
Skip if: you want sleep, activity and food read together.
3. Levels
A US-focused sensor program with a membership app. Levels does not state that it ships outside the US. Check its site for the current offer and price.
Best for: people in the US who want a sensor with a membership app.
Skip if: you live outside the US.
4. Bevel
An AI health coach app. It reads data from wearables such as Apple Watch, Oura and Garmin and covers sleep, recovery, nutrition and lab records. Its site does not mention glucose sensors.
Best for: people who already own wearables and want one view.
Skip if: you want a glucose-first view.
5. Ultrahuman
A smart ring maker that also runs a glucose platform. In the US, its M2 Live pairs with Abbott's Lingo sensor. Check Oura's site for where it ships.
Best for: people who want a ring and a sensor in one ecosystem.
Skip if: you do not want to buy hardware.
6. Health2Sync
A diabetes management app from Taipei, Taiwan. It syncs glucose data from more than 80 devices. Check the app store for markets and features.
Best for: people with diabetes who want a logbook and reports for a clinic.
Skip if: you do not have diabetes and want pattern coaching.
7. mySugr
A diabetes logbook app owned by Roche. It stores data from connected devices and has a paid PRO tier. Check the app store for your market.
Best for: people with diabetes who log daily.
Skip if: you want sleep and activity read alongside glucose.
How do you pick a glucose app?
- You have diabetes: use an app your care team knows, and follow their advice first. An app does not replace them.
- You are healthy and curious: try a sensor for a few weeks. The research says the value is mostly in what you learn about your own habits.
- You want help reading it: choose an app that explains the data, not one that only shows it.
A1C Insights is an app, not a medical device. None of these apps diagnoses you.
What you still control
Pick one change, such as a walk after your biggest meal. Try it for a week. Check the result, then decide.
Frequently asked questions
What is the best glucose app for people without diabetes?
It depends on the job. Some apps are logbooks for people with diabetes, some pair with a sensor, and some read your whole week. If you want help reading the data, choose an app that explains it, not one that only shows it.
Do I need a sensor to use a glucose app?
Not always. Logbook apps store readings from connected devices. Lingo is built around its own sensor. A1C Insights treats sensors as optional.
Is there an agreed healthy glucose range in these apps?
No. Most in-range targets in these apps come from guidance written for people with diabetes. Use any app to learn your patterns, not to label yourself.
Should I use an app if I have diabetes?
Use an app your care team knows, and follow their advice first. An app does not replace them.
