マッスルレーダー

Your body map shows which muscles are recovered and which still need rest. Log a set in seconds, then let the colors plan your next workout.

Open it, and the colors on your body tell you what to train today.

Muscle Radar shows your training log as colors on a body map. A muscle group you just trained turns red, fades to yellow as it recovers, and turns green when it's ready again. Green means go.

WHY COLORS Most logging apps only show "days since". A number is something you have to read and work out. A color is something you understand the instant the app opens. That difference is the whole point of this app.

The colors follow the idea of supercompensation: a muscle needs time to recover before it gets stronger. Recovery days are set per muscle group, and you can change them anytime to match your own pace.
