About FastZen: Intermittent Fasting
Fasting made simple — and actually enjoyable. FastZen is a beautifully designed intermittent fasting tracker that helps you reach your goals with 16:8, 18:6, 20:4, OMAD and extended fasts. Whether you want to lose weight, build healthier habits or simply feel better, FastZen keeps you motivated from your first hour to your finish line. WHY YOU'LL LOVE FASTZEN • EFFORTLESS TRACKING — Start any fast in one tap. A live countdown and a smooth progress ring show exactly where you are. • LOCK SCREEN & DYNAMIC ISLAND — Follow your fast at a glance with Live Activities, without even opening the app. • APPLE HEALTH SYNC — Fasting sessions and your weight are saved to Apple Health automatically. • BODY TRACKING — Log your weight and water intake and watch your progress trend over time. • 16 PROTOCOLS + CUSTOM PLANS — From beginner-friendly 12:12 and 16:8 to 24, 48 and 72-hour fasts — or create your own schedule. • SMART REMINDERS — Get notified when your eating window opens and closes, and never miss the end of a fast. • CHALLENGES & STREAKS — Stay consistent with weekly challenges and keep your streak alive. • PROGRESS YOU CAN SEE — Weekly charts, a calendar heatmap and clear stats show how far you've come. • PRIVACY FIRST — Your fast is hidden when you switch apps, and you can export your data anytime. HOW IT WORKS 1. Answer a few quick questions so we can tailor a plan to your goals. 2. Pick your protocol — 16:8, 20:4, OMAD or fully custom. 3. Start your first fast and let FastZen handle the rest. FASTZEN PREMIUM FastZen is a subscription app. Every plan begins with a 7-day free trial, and you can cancel anytime in your App Store account settings before the trial ends.
