Track your fasting, understand your body, and build habits that actually stick. Free Fast 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.

About

Keepfasting

Features
Read full description

Keepfasting is a simple, intermittent fasting timer built around one idea: you should be able to glance at your Home Screen and instantly know whether you can eat. No accounts to create and no calorie counting. Just a clear countdown and a widget that tells you what you need to know at a glance. TWO WAYS TO TRACK Fixed Schedule Set the time your eating window opens once, and it repeats automatically every day. No daily interaction required. Log My Meals Tap "I Just Ate" or "Start Fasting" whenever it happens, and the app times your cycle from there. A WIDGET THAT'S ACTUALLY USEFUL Add Keepfasting to your Home Screen or Lock Screen and see your current phase in red for fasting or green for eating, with a live countdown that updates in real time. In Dynamic mode, a quick-log button on the widget lets you log a meal without even opening the app. A PROGRESS RING WORTH LOOKING AT Choose whether the ring fills up as your phase progresses or counts down as your deadline approaches, whichever mental model works best for you. A custom slider lets you fine-tune your plan with the red and green split as the control itself. REMINDERS, IF YOU WANT THEM Turn on optional local notifications for when your eating window opens and when it closes. They're off by default, so the app stays out of your way until you ask for it. ANY PLAN YOU LIKE Choose from quick presets like 16:8, 18:6, and 20:4, or fine-tune any custom schedule from 12:12 to 23:1 to match your routine. Your data stays on your device. There is no account, no login, and nothing to sync to a server. Download Keepfasting and start your next fast with a clear view of where you stand.
