Track your fasting, understand your body, and build habits that actually stick. FastIF gives you a clean, distraction-free timer with real insights — streak tracking, weight trends, hydration, HealthKit sync, and more. Key Features: Fasting Timer – Start and stop your fast with one tap. See your elapsed time, fasting stage, and end goal at a glance. The timer keeps running in the background and on your lock screen — always where you need it. Home Screen Widget – Glance at your fasting progress without opening the app. The live widget shows your current stage and time remaining right from your Home Screen. Stats & Trends – Visualize your progress over time. Weekly completion rates, average fasting duration, longest streak, and more — all presented clearly so you actually understand how you're doing. Unlimited History – Every fast you've ever completed, logged and browsable. Filter, review, and reflect on your journey from day one. Custom Protocols – Go beyond 16:8. Build any fasting schedule that fits your life — OMAD, 5:2, custom windows — and save it for one-tap reuse. Per-Day Scheduling – Set different fasting windows for different days of the week. Life isn't uniform, and your protocol doesn't have to be either. HealthKit Sync – Automatically log fasting activity to Apple Health. Your data stays on your device, always private. Hydration & Weight Tracking – Log your water intake and body weight alongside your fasts. See how your habits connect over time. Data Export – Export your full history as a CSV. Your data is yours. Free, No Ads, No Subscription. FastIF is free to download with no ads and no tracking. The core fasting timer, Home Screen widget, HealthKit sync, and recent history are completely free — forever. A one-time Supporter Unlock  gives you full access to Stats & Trends, Unlimited History, Custom Protocols, Per-Day Schedule, and CSV Export. Pay once, own it forever. Medical Disclaimer
