About
MEDICAL DISCLAIMER: FastWise does not provide medical advice, diagnosis, or treatment. Always seek the advice of your doctor or another qualified healthcare provider in addition to using this app and before making any medical decisions, starting any fasting regimen, or changing your diet. (Full disclaimer below.)
FastWise is the intermittent fasting companion that actually explains *why* a protocol fits your life — then coaches you through week one.
PERSONALIZED WIZARD
Answer 5 quick questions about your schedule, goals, and experience level. FastWise generates a named IF protocol (16:8, 18:6, OMAD, or a gentler start) with a plain-English rationale tailored to you — not a generic plan from a quiz.
7-DAY ACTION PLAN
Every protocol comes with a day-by-day first-week plan. Start with a shorter fast on Day 1 and build up gradually to your target window by Day 5. Each day includes a hunger-management tip and a daily checkbox to build momentum.
AI COACH — ASK ANYTHING
Your AI coach knows your current fast duration and protocol. Ask "Does black coffee break a fast?", "I'm 10 hours in and starving — help!", or "I have a work lunch today — how do I adjust?" Get direct, evidence-grounded answers, not a wall of disclaimers.
FASTING TIMER
A glanceable countdown shows exactly how much time is left in your fast. Start and end fasts with one tap. Every session is logged automatically, and a streak counter tracks consecutive days meeting your target.
FAST-BREAKING QUICK REFERENCE
A searchable guide covering coffee, gum, electrolytes, diet soda, and 10+ more common questions — so you never accidentally break your fast and never waste a coach question on something simple.
WEIGHT LOG + STREAK TRACKER
Log your weight manually to track progress. See your average fast duration, goal-met streak, and a weekly summary without the noise.
FREEMIUM — FULLY USABLE FREE
Free users get 3 saved protocols and 5 AI coach questions per day. Premium unlocks unlimited wizard re-runs, unlimited coaching, protocol adjustments after plateaus, and macro guidance for your eating window.
