Frequently Asked Questions

How does Lean calculate my protein target?

Lean uses your current weight and treatment phase to calculate a daily protein target. During the active weight-loss phase, the target is higher to help preserve muscle mass. The calculation follows general clinical guidelines — always confirm with your healthcare provider.

Why is the Progress chart empty?

The Progress chart needs at least two weight entries spanning 14 days or more to display meaningful trends. Keep logging your weight regularly and your chart will appear.

Can I edit or delete a past entry?

Yes. Go to More > History, find the entry you want to change, swipe left to delete, or tap it to edit the details.

Does Lean share my data?

No. All your data is stored locally on your device. Lean does not have user accounts, does not collect analytics, and does not share or sell any data. See our Privacy Policy for details.

How do I export my data?

Go to More > Export my data. Lean will generate a JSON file containing all your logged meals, doses, weights, strength sessions, side effects, and profile information. You can share this file via AirDrop, email, or any other method.

What is the Tapering schedule?

The Tapering schedule helps you track your doctor's plan for gradually reducing your GLP-1 medication dose. Lean does not create taper plans — you enter the schedule your care team provides, and Lean tracks it week by week.

Does Lean give medical advice?

No. Lean is a tracking tool only. It does not diagnose, treat, or recommend medication changes. Safety alerts are informational — always consult your healthcare provider for medical decisions.

How do I set up reminders?

Go to More > Reminders. You can enable meal reminders (up to 3 per day), a weekly weigh-in reminder, and dose day notifications. Lean will ask for notification permissions when you first enable a reminder.
