What it is

A nutrition tracker from the Stronger By Science team. Clients log by photo, voice, barcode or search, and the app recalculates their energy expenditure each week from what they ate and how their weight moved.

Best for

Clients who have given up on slower food diaries, and coaches who want targets based on data rather than a formula. The logging speed is the whole point.

Watch out for

There is no free tier, so it is a cost you are asking clients to take on. AI photo estimates are estimates — portion sizes still need a human eye.

Alternatives & neighbours

Other nutrition options worth comparing.

MyFitnessPal

Nutrition

The food diary most clients have already installed, with the largest branded-food database — convenient, if less precise than the alternatives.

Cronometer

Nutrition

A food diary with unusually careful data — micronutrients included — plus a professional view that lets a coach see a client's logs.

Cal AI

Nutrition

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