Everything, in one app

Food, training and progress in the same place, because they are the same problem.

One honest number

Your BMR is the daily budget. Food spends it, steps and workouts earn it back. What is left is your deficit or your surplus, with the whole ledger behind it.

A food diary that takes seconds

Photograph the plate, scan the barcode, or describe the meal in plain words. Set the portion and the calories scale with it.

Macros without the maths

Protein, carbs and fat per meal and per day, so your nutrition is never a mystery.

A gym log that keeps up

Form animations for every movement, rest recommended per exercise, and a live session that logs your sets as you go.

Progress you can actually see

Weight trend, strongest lifts, tonnage per muscle, and a per-exercise chart that tells you whether the load is really going up.

History that never lies

A skipped day is never counted as a zero. Your averages are built only from the days you actually logged.
