Calsculator

Free AI calorie counter · Android and iPhone

AI calorie counter from a photo

Point the camera at your plate — the app recognises the dish, estimates how much of it is there and counts the calories along with protein, fat and carbs. No barcodes, no food database, no subscription.

A photo instead of a barcode or a food database

No hunting for “homemade stew” in a catalogue and no guessing grams: the AI recognises the dish and estimates the portion from the plate and the cutlery.

The AI asks when the photo cannot tell

What is inside a dumpling, what dressing is on a salad, whether the coffee is sweetened — none of that is visible. The app asks one question and recalculates the calories from your answer.

Calorie and macro targets that fit you

Height, weight, age and the pace you want give you a daily target for calories and macros. From there you always see what is left for today.

Your food diary stays on your phone

The diary lives in the app itself; only the photo is sent for analysis. We ask for your email once — so there is somewhere to keep a backup.

Install the AI calorie counter on Android

  1. 1Tap “Download” — your browser will ask whether to keep the file. Keep it.
  2. 2Open the downloaded file. Android will warn that the source is unknown — allow installs from your browser in the settings screen it opens.
  3. 3Go back and tap “Install”.

The app is not on Google Play, which is why Android asks for that permission by hand. The file is signed with the developer key, so updates install over the old version and the diary survives.

On iPhone — no App Store needed

  1. 1Open app.calsculator.com in Safari — the app runs right in the browser.
  2. 2Tap “Share” in the bottom bar and choose “Add to Home Screen”.
  3. 3Launch it from the home screen: no address bar, and the camera and the diary work exactly the same.

The same works on Android if you would rather not deal with the APK. A plain browser tab is fine too — the home screen icon only removes the address bar.

Honestly, this is an early version
