Full description
Free · Works offline · No account needed. JustFast is a simple intermittent fasting app and fasting timer for everyday use. Pick a 16:8, 18:6 or OMAD plan, tap start, and see how much time is left of your fast and of your eating window. No account and no long setup: your first fast starts in seconds. New to intermittent fasting? A plan like 16:8 means 16 hours of fasting followed by an 8-hour eating window. Many beginners start with 12:12 or 14:10 and move to 16:8 or 18:6 when it feels comfortable. JustFast explains each plan in plain words and lets you switch at any time. FREE FOREVER • The fasting timer and every plan, including open-ended and 36, 48 and 72-hour fasts • Reminders and the home-screen widget • Water tracking • History, fasting phases, edits and adding a past fast START IN SECONDS • Presets from 8 to 24 hours, including 12:12, 14:10, 16:8, 18:6 and 20:4 • OMAD (one meal a day, 23:1) • Extended 36, 48 and 72-hour fasts • Custom fasts of any length • Open-ended fasts that count up until you decide to stop • Edit the start time if you forgot to press start, or add a past fast later FASTING PHASES Follow the approximate phases of a fast, hour by hour, right on the timer. The phase times are general guidelines that vary from person to person. They are not medical advice. EATING WINDOW COUNTDOWN When a fast ends, JustFast counts down your eating window as well, so you always know how much time you have left to eat before your next fast. WEEKLY PLAN AND WEEKLY REVIEW Plan which days you fast and for how long. Each week, a short Weekly Review shows what you completed and suggests a calm next step. No guilt and no nagging. STREAKS, ACHIEVEMENTS AND HISTORY • Streaks with a grace period for busy days • Achievements for your milestones • A calendar plus 7-day and 30-day charts of your fasting hours • Export your history as a CSV file WEIGHT AND BMI Log your weight, follow your trend and BMI, and optionally sync your weight with Health Connect. REMINDERS AND WATER Optional reminders to start your fast and a notification when your fast is complete. You choose the time. Log a glass of water with one tap. PRIVATE AND SIMPLE • No account, no email, no sign-up needed • Your fasting and weight data stay on your phone unless you turn on cloud backup • Works offline • The timer screen is ad-free; small banners appear on secondary screens JUST FAST PLUS (OPTIONAL) Plus removes the ads and adds long-term Insights (90-day, 1-year and all-time trends, and fasting next to your weight) and cloud backup with sign-in.
