SUBSCRIPTION REQUIRED
Zen Lean is free to download. An active subscription or eligible trial is required to use the app after onboarding. Monthly and yearly plans are available. See the subscription screen for current prices and any trial offer. Photo analysis has a daily limit, including for subscribers.
Subscriptions renew automatically unless canceled at least 24 hours before the current period ends. Manage or cancel your subscription in your Apple account settings.
YOUR ACCOUNT AND DATA
Meals, weight, water and fasting records sync through your account. AI meal analysis, barcode lookup and connected health services use external services when you use those features. Optional usage analytics can be turned off in Settings. See the privacy policy for how data is handled.
Zen Lean supports personal awareness and self-tracking. It is not a medical device and does not diagnose or treat conditions. Consult a qualified healthcare professional before changing your diet or fasting routine.

A smoother start.
Setting up with Apple Health is simpler, signing in with Apple or Google before you have an account now guides you to set up your plan, and notification prompts wait until after your account is created.
