AI apps that count carbs from a photo are only useful if the numbers are right. Here's what our research on human carb estimation shows, how we tested Carbsnap against dietitians, and where photo AI still fails.
We compared the best carb counting apps of 2026 — Carbsnap, MyFitnessPal, Carb Manager, mySugr, Cronometer, MacroFactor — for diabetes, keto, and macros.
Carb Manager and Carbsnap both count carbs — but for different people. Keto vs diabetes, manual vs photo-first, and what each costs. An honest look.

A practical, judgment-free guide to carb counting for newly diagnosed diabetics: what counts, how to estimate, the 3 mistakes everyone makes, and how tools fit in.
