Musclefolio — Gym Workout Log

Musclefolio is a gym workout log that grows your muscle like an investment portfolio. Log your sets as your routine lays them out, and it reads your last session to raise the next weight, a little at a time. Muscle is the one investment that never lets you down. Today's weights, decided for you Hit every target rep last time? Next session adds 2.5 kg (or 1 rep for bodyweight moves). Fell short? The weight holds. Miss twice in a row at the same weight, and it drops 10% so you can build back up. Home shows at a glance which lifts go up today and which hold. See exactly which plates to load Turn the dial to set the weight, and a picture shows the plates for one side of the bar. No math — just load and lift.

When a set is done, the rest ring counts down, ticks 3·2·1 and taps your wrist — even with your wrist lowered. Finished workouts move to your phone on their own once it's back in range.
