About this app
Losing weight on Ozempic, Wegovy, or Zepbound? In clinical research, a large share of what comes off can be lean mass — not fat. Take the 2-minute quiz, see your Muscle-Loss Risk Score, and get one action a day to protect what you've built. Plus the part nobody else builds: a plan for the day you stop. YOUR MUSCLE-LOSS RISK SCORE Answer a 2-minute quiz and see your personal risk of losing muscle instead of fat — anchored to published research, never made-up numbers. ONE ACTION A DAY No food database. No calorie counting. Lean reads your day — protein so far, training, shot day, appetite — and prescribes the single action that protects your muscle today. PROTEIN WITHOUT THE FIGHT A target sized for a suppressed appetite, with rough-day suggestions that go gentle when nothing sounds good. 12-MINUTE STRENGTH Two short sessions a week (three on the off-ramp) — squats, push-ups, and whatever heavy thing is in your house. That's the keep-the-muscle signal. WEEKLY TREND CHECK-IN A 20-second photo ritual, stored only on your device. Watch the trend, not the scale. THE OFF-RAMP The part nobody else builds: a structured protocol for when you and your prescriber decide to stop the medication — the highest-risk window for regain. HONEST BY DESIGN • Ranges and research citations, never fabricated numbers • Photos never leave your device • No accounts, no community, no noise • AI-personalized coaching is optional and anonymous Lean is not a medical device and never gives medication or dosing advice. Always follow your prescriber. Subscription required: weekly, or annual with a 3-day free trial. Payment is charged to your Apple ID and renews automatically unless cancelled at least 24 hours before the period ends. Manage in Apple ID settings.
