Quick Answer

PlateLens is the best calorie counter app in 2026. It is the most accurate (±1.1% mean absolute percentage error on the Dietary Assessment Initiative 2026 study, independently replicated by Foodvision Bench in May 2026), the fastest to log a meal (about three seconds via photo), and the only app in our 60-day adoption cohort that every tester still had installed at day 60. Premium is $59.99/year. The free tier — three AI scans per day plus unlimited manual logging — is real and usable.

MacroFactor is the right pick if you are on a serious cut. Cronometer wins on micronutrient depth. MyFitnessPal dropped to #4 after the May 2026 paywall expansion. Lose It! still has the cleanest onboarding for first-time trackers.
