Most fasting apps give you a timer and leave you alone. FastAI gives you a real AI coach powered by Claude (Anthropic) that analyzes your actual meal patterns and tells you why your fasting is — or isn't — working. ✅ Start in 30 seconds — no endless onboarding ✅ Personalized daily message based on YOUR fasting hours ✅ Water tracker + meal log in one place ✅ Real AI analysis, not just a loading bar ✅ No ads. Ever. Supports 16:8, 18:6, and 20:4 intermittent fasting.
