Is Cal AI or MyFitnessPal more accurate?

Not provably. Neither publishes a head-to-head accuracy percentage versus a registered dietitian. Peer-reviewed research places mainstream AI photo estimates in roughly the 5 to 15% error band, and database logging accuracy depends on picking the right database entry and portion. We do not assert specific accuracy figures for either app.

Does MyFitnessPal have an AI photo feature like Cal AI?

Yes, MyFitnessPal added AI photo logging. As of June 2026 it is a paid add-on layered onto a database-first app, rather than the core experience. Cal AI is built around the photo flow from the start. Check the current MyFitnessPal plan details for what the AI feature includes.

Which is cheaper, Cal AI or MyFitnessPal?

MyFitnessPal is the cheaper way to start, because it has a free database-logging tier with AI gated behind a paid plan, while Cal AI is a paid subscription after a trial. Both use paid plans, and pricing changes, so we do not quote competitor prices as fact. Check each App Store or website listing for the current price.

Is there a free alternative to both Cal AI and MyFitnessPal?

Yes. calorietrack.ai is an AI photo calorie counter with a free-forever web tier, no signup to try, and a published accuracy target of within 8% of a registered dietitian. It combines AI-photo-native logging with free web access, which sits between the two apps compared here.

Cal AI's strengths

AI-photo-native, tuned for iPhone.

Cal AI is built around the photo flow. You snap a meal and it estimates calories and macros without you hunting through a database. If your main friction with tracking has always been the searching and the typing, an AI-photo-native app removes most of it, and Cal AI is a polished example on iOS.

The trade-offs are platform and price. As of June 2026, Cal AI is iOS-first, so there is no comparable web or Android path, and it is a paid subscription after a trial. Its food database is smaller than a database giant like MyFitnessPal, because it leans on the model rather than on manual lookups. We do not assert an accuracy figure for Cal AI, the category as a whole sits in the peer-reviewed 5 to 15% band.

MyFitnessPal's strengths

The largest database, everywhere.

MyFitnessPal's strength is breadth. It has one of the largest food databases anywhere, fast barcode scanning, and a long history of community-entered foods, which makes it hard to find a packaged product it does not already list. It also runs on iOS, Android, and the web, so you can log from almost any device.

The trade-off is that AI photo logging is not the core. As of June 2026 it is a paid add-on layered onto a database-first experience, so the snap-a-photo flow can feel like a feature rather than the main event. Database logging is also only as accurate as the entry and portion you pick, which puts more of the work on you than a photo-native app does. Check the current MyFitnessPal listing for what the AI feature includes.

Want AI photo logging that is free on the web?
