Best 8 Glucose Trackers in 2026: Feature Comparison

Introduction

Glooko is the best overall glucose tracker because it pulls data from the widest range of meters, pens, pumps and CGMs. This list covers 8 apps: simple logbooks, CGM apps, and tools with insulin or carb features. Picks are based on verified store listings, not hands-on testing.

Quick comparison table

The table shows each app, who it suits, its platforms and its standout feature. Every app is listed for both iOS and Android, in the same order as the reviews below.

Hardware matters for some of these. Dexcom and FreeStyle Libre are built around their own CGMs. One Drop pairs with the company's meter and test strip subscription. OneTouch Reveal may be tied to OneTouch meters, but the listing we have doesn't confirm that.

Based on the listings, mySugr and Hedia work as standalone logbooks, and Hedia can optionally connect a meter. Glooko works by syncing data from your devices. Dexcom and FreeStyle Libre depend on a sensor.

Most listings don't state pricing, so we've left it out of the table. One Drop and OneTouch Reveal are described as free apps.

1. mySugr

Best for: People who want a simple diabetes logbook for blood sugar and other data.

mySugr is listed on iOS and Android, and the listing says people with diabetes developed it. The standout feature is the logbook format, which keeps entries in one place.

The listing doesn't say which meters or sensors it works with. Check compatibility before you rely on it.

2. Gluroo

Best for: Insulin users with type 1 or type 2 diabetes, especially families and caregivers.

Gluroo is a diabetes management app, and its listing describes remote monitoring by caregivers. That's the standout feature. It suits parents or partners who want to keep an eye on someone's numbers.

It's available on iOS and Android.

3. Glooko

Best for: People who use several devices and want everything in one place.

Glooko syncs data from meters, insulin pens and pumps, CGMs, activity trackers and food trackers. Multi-device syncing is its standout feature.

That breadth earns it the top overall spot. Most other apps here focus on one device or one job, while Glooko collects the lot.

4. One Drop

Best for: People who also track prediabetes, blood pressure or cholesterol.

One Drop is a free app that syncs with Apple Watch, Fitbit and other trackers. That wearable syncing is its standout feature.

It pairs with the company's meter and test strip subscription. Weigh that cost before you sign up.

5. OneTouch Reveal

Best for: People who want a free, basic blood sugar tracker.

OneTouch Reveal is listed on the App Store, Google Play and the web. Web access alongside the mobile apps is the standout feature.

The listing gives limited detail, so we won't guess at features beyond basic blood sugar tracking.

6. Dexcom

Best for: Dexcom CGM users who want readings on their phone.

The Dexcom app shows blood sugar on a smartphone and is a companion to the company's CGM. Checking glucose on your phone is the standout feature.

It needs the Dexcom CGM, so it isn't a standalone logbook.

7. FreeStyle Libre

Best for: People using Abbott's FreeStyle Libre CGM.

The FreeStyle Libre app lets users check blood sugar from a smartphone. Phone-based glucose checks are the standout feature.

Like Dexcom, it requires Abbott's own CGM hardware. You can't just download it and start.

8. Hedia

Best for: People who want carb tracking and insulin dose recommendations in one app.

Hedia tracks blood sugar and carb intake, sends reminders, and can connect to a blood glucose meter. Insulin dose recommendations are the standout feature.

Run any dosing advice past your doctor or care team before acting on it.

Frequently asked questions

What is the best free glucose tracker?

Several apps here are free to download, including One Drop and OneTouch Reveal. Some free apps still depend on paid hardware or subscriptions, though. For simple logbooks, look at mySugr and OneTouch Reveal.

Do I need a CGM to use a glucose tracker app?

No. Logbook apps like mySugr work with manual entries. Dexcom and FreeStyle Libre are built around their sensors, while Glooko can pull in data from meters and CGMs.

Can caregivers see my glucose data?

Gluroo's listing highlights remote monitoring by caregivers. Check each app's sharing settings before relying on it.

Are these apps a substitute for medical advice?

No. Trackers record and display data. They don't replace a clinician. Be careful with dose recommendations like Hedia's, and remember this roundup is based on listings, not hands-on testing.

The verdict

Glooko is the strongest overall pick because it syncs the widest range of devices. mySugr is the runner-up for a simple logbook. If you already use a Dexcom or FreeStyle Libre CGM, stick with that sensor's own app.

Gluroo suits caregiver monitoring, and Hedia covers carb and dose tracking in one place. Confirm device compatibility on the official listing before you download.
