Dietly vs Cal AI
Cal AI is a calorie tracker built around photographing meals. Its site describes photo-based calorie and macro estimation, barcode scanning, manual and custom-food logging, portion estimation using the phone's depth sensors, step tracking via Apple Health and Google Fit, and integrations with other fitness platforms.
Dietly scores one weekly photo out of 100, names the weak point holding the score back, and builds that week's training around it, with food logging attached.
The short answer
Pick Cal AI if you want the fastest way to log a meal from a photo and you already have your training handled.
Pick Dietly if you want the training itself decided from a weekly measurement of your physique, with good-enough food logging included.
What each one costs
Dietly
Free to start. Pro unlocks unlimited scans, the full weekly plan, unlimited logging and the coach. The current price is on the App Store and Google Play listings — we do not restate it here, because a price copied into a second place is a price that goes stale in one of them.
Cal AI
Free to download, but Cal AI publishes no subscription price on its website — the number is shown in the app, and reported prices vary by region and by user. We are not going to quote one we cannot verify.
3-day free trial, as advertised on Cal AI's site.

Where Cal AI is better
- Cal AI's meal photography is its whole product and it is fast. Depth-based portion estimation is a real technical advantage over apps that guess volume from a flat image, ours included.
- If all you want is to stop typing food into a search box, it is a smaller, simpler thing to adopt than a training app.
- It integrates step and activity data from Apple Health and Google Fit out of the box.
Where Dietly is better
- Cal AI counts the input. It has no view on training, and nothing in it looks at the body the calories are for.
- Dietly's camera is pointed the other way: the weekly scan produces the score and the weak point, and the training week follows from them.
- Our pricing is on the App Store and Google Play listings, where a price can actually be kept current, rather than set per user behind a paywall.
