More than a glucose log.
Glucose Buddy gives you a place to record numbers. SNAQ gives you the nutrition layer that explains them, then forecasts the next one.
In short.
Glucose Buddy is a 15-year-old US T2D tracker bundling smart meter, test strips and optional coaching, with a 2013 RCT and an active user base of around 30,000. SNAQ is an AI nutritionist for diabetes, prediabetes and GLP-1 users, with photo carb counting validated at 5.5 g mean absolute error, predictive glucose response, and a 2025 RCT in eClinicalMedicine. SNAQ adds an AI layer that Glucose Buddy's logbook lacks.

Why users switch.
An AI layer on top of the logbook
Glucose Buddy was built before AI photo recognition existed. SNAQ is AI-native and brings carb counting plus coaching into the same place as your readings.
Modern evidence base
Glucose Buddy's most-cited study is from 2013 with 72 participants. SNAQ's RCT was published in 2025 in eClinicalMedicine.
Wider device coverage
Bring Dexcom, FreeStyle Libre, Eversense, Apple Watch, Whoop, Garmin and more. One hub, not a single vendor.
Honest take.
Choose SNAQ if…
- You want nutrition coaching built into the same app as your glucose data.
- You'd rather see your model adapt to your meals than pay separately for human coaching.
- You want device flexibility and a modern evidence base.
Consider Glucose Buddy if…
- You specifically want a bundled glucose meter, test strips and human coaching plan.
- Your care team or employer plan already provides Glucose Buddy.
Bottom line
Glucose Buddy is a logbook with optional human coaching. SNAQ is an AI nutritionist that includes a logbook. If you want guidance, SNAQ does more for less.
Published randomised controlled trial evidence, measured against standard care in T1D patients on automated insulin delivery systems.
