Lean · GLP-1 Muscle Tracker

On a GLP-1 medication? Hit your protein, track your lifts, and see the chart no calorie app shows: weight falling while strength holds. Proof your muscle is staying.

Losing weight on a GLP-1 medication is the easy part. Keeping your muscle is the part nobody helps you with. Lean is the GLP-1 companion built around one promise: lose the fat, keep the strength — and see the proof.

Other apps just count calories with a "GLP-1 mode" bolted on. Lean leads with the thing you actually fear: muscle loss. It coaches your protein, tracks your strength, and around day 14 draws the one chart no calorie tracker will show you — your weight trending down while your lifts hold steady. That's muscle retention, made visible.

PROTEIN, IN TWO TAPS • A daily protein ring with a target sized to your body weight • Two-tap logging — quick chips for the foods and shakes you eat every day • Honest 7-day streak that forgives your low-appetite injection day instead of punishing it • No guilt, no shaming — just a clear "did I get enough protein today"

STRENGTH YOU CAN PROVE • Log your key lifts and bodyweight in seconds • Set a baseline at the start so you have something to hold the line against • See, week over week, that the weight on the bar isn't dropping with the weight on the scale

THE MUSCLE-RETENTION PROOF • The signature chart: bodyweight down, strength flat or up — the muscle is staying • Long-term trends as your journey continues • Export a clean CSV or PDF to share with your doctor or clinician

BUILT FOR THE GLP-1 JOURNEY • Set your medication, dose, and start date • A calm, clinic-quiet design — reassuring, never gym-aggressive or alarmist • Adaptive protein target that scales as your weight changes

FREE FOREVER, NO ACCOUNT NEEDED Log your protein, track your lifts, keep your 7-day history, and use the daily ring and streak — free, for as long as you want. Sign in with Apple is optional. Your data lives on your device.

IMPORTANT — NOT MEDICAL ADVICE Lean is a fitness and self-tracking tool, not a medical device or a substitute for professional care. It does not diagnose, treat, prevent, or manage any condition, and it does not provide medical, nutritional, or pharmaceutical advice. Protein targets and any other figures are general estimates, not a prescription. Always follow the guidance of your own doctor or healthcare provider about your medication, diet, and exercise — especially before changing your protein intake or starting a resistance-training program while on a GLP-1 medication. Never disregard professional medical advice because of something you read in this app.
