Cal AI

A calorie tracker where clients photograph a meal and the app estimates calories and macros — the lowest-effort food logging there is.

What it is

A phone app that logs food from a photo, estimating the dish, portion, calories and macros. Barcode scanning and manual entry cover the rest.

Best for

Clients who will not log food any other way. A rough estimate they actually record beats a precise diary they abandon in week two.

Watch out for

Photo estimates can be far off, especially for oils, sauces and mixed dishes. Use it for awareness and trends, not precise targets, and remember it is a cost to the client.
