A note from the studio
“Every GLP-1 app is a calorie counter with a mode bolted on. Lean leads with the thing that actually matters: muscle preservation.”

Three steps. No account. No tracking.
01
Set your protein target
Based on your body weight, not a generic number.
02
Log meals & lifts
Log your protein and key lifts in seconds.
03
See the proof
Watch weight fall while strength holds — your muscle retained.
