More than a logbook.
SNAQ replaces the guesswork that used to require a dietitian. mySugr replaces the paper logbook. Two different jobs, both useful, often complementary.
In short.
mySugr is a diabetes logbook built around manual entry and the Accu-Chek ecosystem, with peer-reviewed evidence for logbook use. SNAQ is an AI nutritionist for diabetes, prediabetes and GLP-1 users that recognises meals from a photo, predicts the glucose response before you eat, and improved Time in Range by 6.6 percentage points in a randomised controlled trial published in eClinicalMedicine in 2025. mySugr suits structured manual logging for clinic visits; SNAQ adds active coaching on top.
At a glance.
- SNAQ recognises meals from a photo with 5.5 g mean absolute carb error vs lab-verified meals (Herzig 2020). mySugr food logging is mostly manual.
- SNAQ predicts the glucose response before you eat. mySugr stores readings after the fact.
- SNAQ integrates with 20+ CGMs, BGMs and wearables including Dexcom, FreeStyle Libre, Apple Watch, Whoop and Garmin. mySugr is strongest inside the Roche / Accu-Chek ecosystem.
- SNAQ has a published RCT showing a +6.6 pp Time-in-Range improvement (eClinicalMedicine, 2025). mySugr's evidence base covers logbook efficacy and HbA1c improvement.
- Both offer a low-cost premium. The decision is which workflow fits you, not price.
It's about time we take the guesswork out of carb counting and understand better what food does to our bodies. I am thrilled to support SNAQ on that mission.

Why users switch.
From recording to coaching
mySugr stores what you did. SNAQ tells you what to do next, based on your own glucose patterns and a peer-reviewed model.
Photo first, manual when needed
Carb counting drops from minutes of typing to seconds of pointing a camera, with accuracy validated by Bern University Hospital.
Whatever sensor, whatever cohort
Dexcom, FreeStyle Libre, Eversense and 20+ devices. T1D, T2D, prediabetes and GLP-1 in one app.
Honest take.
Choose SNAQ if…
- Your priority is understanding how food affects your blood sugar before you eat, not after.
- You want proactive AI guidance, not just a place to record numbers.
- You value RCT-grade evidence and device flexibility behind the product you use.
Consider mySugr if…
- Your care team specifically uses mySugr for data sharing.
- You're deeply embedded in the Accu-Chek ecosystem and want the tightest possible meter integration.
Bottom line
SNAQ replaces the guesswork that used to require a dietitian. mySugr replaces the paper logbook. If you want both logging and coaching, SNAQ covers both with AI on top.
Published randomised controlled trial evidence, measured against standard care in T1D patients on automated insulin delivery systems.
