An AI coaching app built around fasting windows and habits, against a plain logging tool.
4.7 from 397,778 ratings · Free
A weight-loss app built around intermittent fasting windows, habit scoring and an AI coach that talks you through decisions. Logging exists, but the product is really the coaching relationship and the fasting structure around it.

A camera-first tracker. Point at the plate for an AI estimate you confirm in two taps, or scan a barcode or nutrition label to get exact published figures instead. Built around the idea that a photo estimate is an estimate, with cuisine coverage beyond American food databases. New, and small.

intermittent fasting is your method and you want an AI coach nudging you through the windows and the habits around them. The coaching is the product and it is a reasonable thing to want.
you want a diary, not a coach, and you would rather see the numbers than be talked through them.
Simple is a coaching product with logging attached. KalTrack is logging with no coaching attached. Which one is right depends almost entirely on whether you want to be spoken to.
If fasting windows are how you eat, Simple builds its whole structure around them — when your window opens, how the habits stack, an AI coach to interrogate when you are wavering. KalTrack has none of that and will not tell you when to eat.
What KalTrack gives you instead is a clear view of what you actually consumed, quickly, with the estimate labelled as an estimate. No conversational layer sitting between you and the number, and no interpretation you did not ask for.
There is also a subscription-shape difference worth checking before you commit to either. Coaching apps in this category are typically subscription-first with a short trial. KalTrack is free to download with a daily free scan allowance, and Pro is $9.99/month or $29.99/year with the billed price shown before the trial starts and cancellation left in Apple's own flow. Compare the total commitment, not the headline.
Method: figures come from each app's public App Store listing on the day this page was built, and from each app's own published pricing. Features were checked against the apps' own descriptions. We make KalTrack, so treat this as our account of the difference, not a review.
