When Cal AI is the better choice
Cal AI is built around the camera, and it may suit you better if:
- You’d rather take a photo than type or talk. Cal AI starts from a photo of your meal, with barcode scanning and a typed description as other options.Source: calai.app
- You wear an Apple Watch and want the app on it. Cal AI runs on iPhone, Apple Watch and Android.Source: Cal AI on the App Store (US), Cal AI on Google Play (US)
When FitDiary may suit you better
FitDiary puts typing and voice first, which helps when a photo can’t show what’s in the dish:
- You often eat things where the ingredients aren’t visible, like a stew or a smoothie. Say what’s in it: “chicken and veg stew, about a ladle and a half”.
- You want to correct a number just by saying what’s different. Tell FitDiary’s chat “it was only half a portion” and the entry updates before you save it.
- You’d rather log without the camera, by typing or dictating.
- You want to ask about your own day, such as “How much can I still eat today?”
- You want a free plan with no time limit, including the barcode scanner and 3 chat messages a day. Photo logging is there if you move to PRO.
A free Cal AI alternative: what’s free and what’s PRO
On the free plan you get 3 chat messages a day, to log a meal in one sentence or ask what to eat next. You also get the barcode scanner, food search and water and weight tracking, with no time limit. Your daily calorie target is worked out from your age, height, weight and activity, and updated as your weight changes.
PRO adds unlimited chat messages and a calorie estimate from a photo of your plate. Before you subscribe, the App Store or Google Play shows the PRO price in your currency. There are no ads on either plan. All the details are under pricing.

How to switch from Cal AI

- FitDiary can’t import a food diary from Cal AI or any other app, so your diary starts on the day you join.

- If your steps, workouts and weight are in Apple Health or Health Connect, connect whichever you use and FitDiary brings them in.
- Log your next meal the way you’d describe it to a friend, check the calories and tap “Add to diary”.
Say what you ate, check it, then save
Type or say “a chicken wrap and a banana” and see the calories before they go in your diary. If it’s wrong, say what to change. The free plan has no time limit.

Frequently asked questions
Is there a free alternative to Cal AI?
FitDiary has a free plan with no time limit: 3 chat messages a day to log meals by typing or voice, the barcode scanner, food search, and water and weight tracking. Calories from a photo come with PRO.
Is Cal AI free?
Cal AI is free to download, but its App Store listing says food scanning results need a subscription. Its website, calai.app, offers a 3-day free trial.
Can FitDiary count calories from a photo?
Yes, with PRO. Take a photo of your plate and FitDiary shows what it found and the calories, so you can check and correct them before saving.
What if the calories are wrong?
Tell it in the chat, for example “it was only half a portion” or “that’s turkey, not pork”, and it reworks the entry before you add it to your diary. Calories from a description or a photo are estimates, so if you want to be precise, type the weight in grams.
Can I log meals by voice?
Yes. Tap the microphone in the chat and say what you ate. On the free plan, each dictated message counts as one of your 3 chat messages a day.
Can I move my Cal AI history to FitDiary?
No. FitDiary can’t import a food diary from another app, so you start a fresh diary.
