Skip the typing. Keep the carb count.
Carb Manager assumes you'll type your meal into a database. SNAQ assumes you'll take a photo. Same number on the plate, different commitment.
In short.
Carb Manager is a calorie and carb tracker built around keto and low-carb diets, with a strong recipe and meal-plan library. 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 published RCT. They serve different intents: diet adherence versus glucose outcomes.

Why users switch.
From typing to photographing
Photo logging takes seconds. Database entry with portion sliders takes a minute or more. Same carb output, less friction.
Glucose outcomes, not just carb counts
Carb Manager helps you stay under a target. SNAQ helps you see what each meal does to your blood sugar.
Built for diabetes, not for diet
Carb Manager's design is for keto adherence. SNAQ's design is for glucose-driven cohorts: T1D, T2D, prediabetes, GLP-1.
Honest take.
Choose SNAQ if…
- Diabetes, prediabetes or a GLP-1 medication is part of your reality.
- You prefer photo input to database lookup and portion sliders.
- You wear a CGM or wearable and want a single hub.
Consider Carb Manager if…
- You're committed to keto or low-carb and want a deep recipe library.
- You prefer database entry over photos for full ingredient control.
Bottom line
If you're tracking carbs to manage diabetes, SNAQ is the lower-friction path with the better evidence. If you're tracking carbs to follow a strict keto plan, Carb Manager's library has the edge.
Published randomised controlled trial evidence, measured against standard care in T1D patients on automated insulin delivery systems.
