Simple Fasting App vs Fasting Timer & Hydration Log

A clearer way to follow your fast—built around your time, not your data. Simple Fasting App gives you a calm, focused place to plan a fast, follow your progress, and understand your routine. No ads, subscriptions, in-app purchases, or account required. CHOOSE YOUR RHYTHM Choose 12:12, 16:8, 18:6, 20:4, or a 24-hour fast—or set a custom duration. Adjust your start time when your day changes, and finish a fast early whenever you need to. FOLLOW EVERY FAST See elapsed and remaining time, start and end times, your current plan, and completion status in one clear live view. An optional reminder can let you know when your planned fasting window ends. EXPLORE FASTING INSIGHTS Choose whether to see time-based fasting stage estimates as your fast progresses. Each stage includes clear context so you can understand what the estimate means—and what it does not. UNDERSTAND YOUR ROUTINE Review completed sessions, total fasts, average duration, your longest fast, weekly averages, and monthly patterns. Open any day to see its timeline and session details. KEEP PROGRESS IN VIEW Follow an active fast beyond the app with Home Screen widgets, Live Activities, and Dynamic Island on supported iPhone models. MAKE IT YOURS Choose light, dark, or system appearance and select an accent color that suits you. PRIVATE BY DESIGN No sign-up. No account. No ads. No subscriptions. No in-app purchases. Your fasting history stays on your device, and Simple Fasting App does not collect or sell your data. Fasting stages are general estimates based on elapsed time. They do not measure your individual metabolic response and are not medical advice. Fast with clarity, at your own pace.

An intermittent fasting timer that tells you exactly where you are: hours elapsed, hours left, and which metabolic stage your body just entered. Most fasting apps stop at a countdown. This one draws the whole fast on a stage timeline — fed state at 0h, glycogen use at 4h, fat burning at 8h, ketosis at 12h, autophagy at 16h, deep ketosis at 24h — so the number on screen finally means something. Underneath it sits a hydration log, because water is what makes the last four hours bearable, and a Learn library that answers the questions every beginner hits in week one. WHAT YOU GET - Know your fasting window at a glance: a live ring timer with hours elapsed, time remaining and the exact clock time your eating window opens - Follow your body, not just the clock — a metabolic stage timeline that fills in as you pass 4h, 8h, 12h, 16h and 24h - Start in two taps with 16:8, 18:6, 20:4 or OMAD 23:1, and get a completion notification the moment you hit your goal - Hit your water target every day — a 250 / 500 / 750 ml quick-add, a custom amount, an adjustable daily goal and a progress ring for today - See whether it is working: total fasts, average length, longest fast, a consecutive-day streak and a bar chart of your last ten fasts - Close each fast honestly — rate how it felt and your energy level from 1 to 5, then browse the full history of every fast you finished PERFECT FOR - Beginners starting 16:8 who want to know what is happening inside the fast, not just when it ends - OMAD and 20:4 fasters chasing longer ketosis and autophagy windows - Anyone who keeps forgetting to drink water once meals disappear from the day - People who quit fasting before because the hours felt pointless and invisible WHY NOT JUST USE A KITCHEN TIMER? A timer tells you 6:42 is left. It cannot tell you that you crossed into fat burning two hours ago, when your eating window opens tomorrow, how long your streak is, or whether last week's fasts were actually longer than this week's. That context is the difference between counting down and building a habit. PRIVACY Everything stays on your iPhone. No account, no sign-up, no servers — your fasts, water logs and notes are stored on the device and are never uploaded. FULL ACCESS This is a paid app: one plan unlocks everything — all four fasting protocols, the live timer and stage timeline, unlimited history, insights and charts, the hydration log and the full Learn library. Choose weekly, yearly, or a one-time lifetime purchase. No ads at any tier. This app is a fasting timer and hydration log for general wellness, not medical advice. Talk to a doctor before fasting, especially if you are pregnant, diabetic or managing a health condition. Pick 16:8, tap Start, and watch your first stage light up tonight.
