What it is

A fasting and weight-loss app combining fasting timers with AI-powered food scanning, personalized meal plans, and an "AI Health Chat" nutrition companion, alongside a Fastic Score blending fasting/hydration/sleep metrics and a "Protein Fasting" feature pairing high-protein recipes with fasting for muscle-sparing fat loss. Plus subscription runs $12.99-$14.99/month, dropping to roughly $9.33-$10/month on a 3-month plan, or $79.99/year (~$6.67/month) annually — with a 14-day "Feel Good Guarantee" refund rather than a traditional free trial (you pay upfront, refundable within 14 days). 50M+ downloads.
