How this guide was made
Glucose publishes this guide and is one of the apps considered. To keep that conflict visible, we do not present the list as an independent laboratory ranking.
We selected ten active US iPhone apps with a clear role in glucose or diabetes tracking. We reviewed their current first-party App Store descriptions for:
- The main tracking workflow
- iPhone availability
- Device and health-platform connections
- Reports or care-team sharing
- Whether the app is broad, hardware-specific, or CGM-focused
- Important limitations or regional dependencies
We did not install and clinically test every app, audit its privacy implementation, or verify every paid plan. “Best” therefore means best suited to a stated use case—not a universal medical recommendation.
Quick recommendations
| App | A practical reason to consider it |
|---|---|
| Glucose | A simple, all-in-one iPhone and iPad logbook |
| mySugr | Listed Accu-Chek connections and region-specific PRO tools |
| OneTouch Reveal | A workflow centered on compatible OneTouch meters |
| Health2Sync | Broad device syncing and family or provider sharing |
| Glooko | A care-team platform with extensive device compatibility |
| Glucose Buddy | Food database, Dexcom listing, and cross-platform access |
| Diabetes:M | Detailed diabetes logging, tools, and Apple Watch access |
| Sugarmate | CGM visualization for users and caregivers |
| Gluroo | Shared diabetes logging for families and care circles |
| Diabetes ++ | A lightweight log that stores data through Apple Health |
The order begins with Glucose because this is the Glucose website, not because we claim it is objectively best for every person. The use-case descriptions below are the meaningful part of the comparison.
1. Glucose — for a focused all-in-one iPhone log
Glucose records blood sugar, insulin, medications, carbs, A1C, blood pressure, weight, ketones, tags, and notes in one daily timeline. It offers averages, estimated A1C, Apple Health writing, and PDF or CSV reports.
It is best considered as a personal record-keeping app. It does not calculate insulin doses, measure glucose, or replace regulated device software.
2. mySugr — for parts of the Accu-Chek ecosystem
mySugr combines manual logging with listed connections for several Accu-Chek meters. Its App Store description also lists Apple Health, reports, patterns, estimated HbA1c, and PRO features such as expanded reports and a bolus calculator in select countries.
Check regional availability carefully. A device or PRO feature shown in one country may not be offered in another.
3. OneTouch Reveal — for compatible OneTouch meters
OneTouch Reveal is built around syncing compatible OneTouch meters. It organizes readings, highlights recurring high or low patterns, supports goals and reminders, and can produce a report for a care team.
It is a natural candidate for someone already using supported OneTouch hardware rather than someone looking for a hardware-neutral logbook.

4. Health2Sync — for broad syncing and sharing
Health2Sync lists support for more than 40 Bluetooth meters, blood pressure monitors, and scales. It also includes logging, lab-result tracking, charts, family sharing, PDF reports, Excel export, Fitbit, and Apple Health.
Its larger feature set may appeal to people coordinating several devices or sharing records with family. Confirm which devices work in the US.

5. Glooko — for device breadth and care-team connection
Glooko describes a platform that syncs data from more than 200 diabetes and health devices. It supports glucose, insulin, weight, exercise, food, medications, reports, and remote care-team collaboration.
This is broader than a simple personal log. It may be a better fit when a clinic already uses Glooko or when several compatible devices need to feed one platform.
6. Glucose Buddy — for food context and a cross-platform app
Glucose Buddy lists glucose, medication, insulin, weight, activity, A1C, a food database, carb tracking, reports, Apple Health, and Dexcom integration. It is available on iPhone and Android.
Its food and premium feature set may be valuable if meals are central to the workflow. Someone seeking a quieter logbook may prefer a more focused app.

7. Diabetes:M — for detailed logging and Apple Watch
Diabetes:M provides extensive logging, reports, charts, nutrition data, tools, Apple Health integration, and an Apple Watch app. Its listing describes support for both Type 1 and Type 2 diabetes as well as family monitoring.
The depth can be useful for someone who wants detailed configuration. It may feel heavier than necessary for basic glucose records.

8. Sugarmate — for CGM visualization
Sugarmate by Tandem focuses on making CGM data easier to view and share. Its listing highlights enhanced visualization, a digital diary, customizable tools, and caregiver sharing.
It belongs in a different subcategory from a manual glucose logbook. Confirm current CGM compatibility before choosing it.

9. Gluroo — for collaborative diabetes logging
Gluroo combines CGM and pump connections, manual logs, food-photo tools, exercise imports, device-site reminders, and a shared “GluCrew” workflow for family members or caregivers.
Its collaborative model is distinctive. It may be more appropriate for a family or caregiver workflow than for someone who only wants a private manual log.
10. Diabetes ++ — for a lightweight Apple Health-based log
Diabetes ++ focuses on glucose records, tags, reminders, graphs, and PDF reports. Its listing says data is read from and written directly to Apple Health rather than stored in the developer's own cloud database.
The iPhone app's App Store update history is less recent than several alternatives in this guide, so review the current compatibility and support status before adopting it.

Choose the workflow, then the app
Start with the job you need done:
- For simple manual logging, prioritize speed and readable history.
- For a specific meter or CGM, start with confirmed device compatibility.
- For a clinic workflow, ask which platform your care team supports.
- For caregiver sharing, review permissions and account access.
- For dosing or automated delivery, use only the appropriate regulated and clinician-approved system.
