Cal AI vs MyFitnessPal
Two tools coaches often weigh against each other, compared on the same terms.
Cal AI
A calorie tracker where clients photograph a meal and the app estimates calories and macros — the lowest-effort food logging there is.
MyFitnessPal
The food diary most clients have already installed, with the largest branded-food database — convenient, if less precise than the alternatives.
Pricing
Cal AI: Subscription app with a trial
MyFitnessPal: Free tier exists; barcode scanning and macros moved behind Premium

What it is
Cal AI
A phone app that logs food from a photo, estimating the dish, portion, calories and macros. Barcode scanning and manual entry cover the rest.
MyFitnessPal
The default calorie tracker. Its advantage is not accuracy, it is that the food your client actually ate is probably already in the database, and they probably already have an account.
Best for
Cal AI
Clients who will not log food any other way. A rough estimate they actually record beats a precise diary they abandon in week two.
MyFitnessPal
Clients new to tracking, where the goal is awareness and adherence rather than precision to the gram.
Watch out for
Cal AI
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.
MyFitnessPal
The database is crowd-sourced and full of wrong entries. Several features coaches rely on — including some macro and scanning tools — have moved into the paid tier over the years, so check what is free before you build a protocol on it.
Editorial comparison — nothing here is paid placement. Pricing changes often; treat the vendor’s own page as the truth. How we review
