Our Rankings
Every ranking starts with the apps that can do the job. Nutrition rankings then order them on measured accuracy first, features second and price third. Our sleep, mind and body rankings aren’t lab-measured, so they rest on features, free tier, price and consensus standing, and they say so. Prices are as of November 2026.

Why one app leads most nutrition lists: our nutrition rankings put measured accuracy first, and PlateLens measured the lowest error in both photo mode and manual entry. Where an app can’t do the job, it can’t lead: PlateLens has no fasting timer, so Zero tops our fasting ranking.How rankings are ordered.
