Not medical advice
LeanFast provides general wellness information. It is not a medical device and does not diagnose, treat or prevent any condition. Talk to a doctor before fasting if you are pregnant or breastfeeding, have diabetes or another medical condition, take medication, or have a history of disordered eating. Stop fasting and seek help if you feel unwell.
Nutrition information
Scanner results, nutrition values and grades are estimates. They may be wrong, especially for unclear photos or labels. Always check the packaging when it matters, for example for allergies.
LeanFast Prism subscriptions
- Prism is available as a monthly or yearly auto-renewing subscription, or as a one-time lifetime purchase. Prices are shown in the app before you buy.
- Payment is charged to your Apple ID when you confirm the purchase. The subscription renews automatically unless you cancel at least 24 hours before the end of the current period.
- If you start a free trial, it converts to a paid subscription when it ends unless you cancel at least 24 hours before. Any unused part of the trial is forfeited when you buy a subscription.
