Before choosing a calorie tracking app, compare how it logs food, where your targets come from, whether it tracks body changes beyond the scale, and what the subscription terms are before you pay. Below is a short checklist, then honest comparisons of FitCommit with nine other fitness apps. FitCommit is an iPhone app that combines an AI body scan, food logging, guided workouts and a transformation preview.

As one example, FitCommit lets you log food by photo, barcode, nutrition label, voice or text, and you review and edit every estimate. Its Body Scan uses AI to give your body fat percentage and lean mass from three phone photos.
FitCommit is an iPhone app that logs your food and also measures your body fat percentage and lean mass from three phone photos. MyFitnessPal focuses on food logging and does not measure body fat from photos. In FitCommit, your calorie and macro targets come from your scan's lean mass, your weight and your goals, and they update when you rescan.
FitCommit builds your workouts in the same app as your food targets and your Body Scan. Your weekly plan is built from your answers, with a make-up option for missed days. Each exercise has a demo video. You can see last time's weight and reps and reuse them in one tap. After a workout, rate how each exercise felt, and FitCommit suggests your weight for next time. Group exercises into supersets when you want to.
Most workout apps do not scan body fat, and most food apps barely train. FitCommit does both.
