123 Cal
What it is
123 Cal is an iPhone app for tracking calories and macronutrients with less typing. You take a photo of a meal and its AI returns an estimate of calories, protein, carbs, fats and fiber, along with a likely range and the assumptions behind it. You can then correct portions or add items the camera cannot see, such as cooking oil. Packaged foods can be logged by scanning a barcode or reading a nutrition label with AI. The app tracks progress against daily calorie and macro targets, saves favorite meals for quick relogging, syncs with Apple Health and shows remaining totals on Apple Watch. It is free to download, and unlimited scanning requires a Pro subscription.

Editor's notes
More context from AI BirdView
Photo calorie counters often present a single confident number, which can be misleading. 123 Cal takes a more honest approach by showing a likely range and the assumptions it made, then inviting you to fix anything the camera missed, like a spoon of butter in the pan.
- Estimates calories, protein, carbs, fats and fiber from one meal photo
- Lets you adjust portions and add hidden extras before saving
- Scans barcodes and reads nutrition labels for packaged foods
- Writes nutrition and water data to Apple Health with your permission
- Shows calories and protein remaining on Apple Watch
The app is best for iPhone users who want to hit a daily protein goal or keep a loose eye on calories without weighing and typing every ingredient. A practical tip: save the meals you eat most often, such as your usual breakfast, so they can be logged with a single tap, and take a moment to add cooking fats after each photo, since the company notes these are the details a picture cannot capture.
