Intermittent fasting timer: 16:8, 18:6, OMAD. Free forever, no subscription.
Fastivo is a simple, calm intermittent fasting timer and tracker – and free forever: no subscription, no purchases, no trial, no discount pop-ups, no feature behind a paywall, no Pro version. No account, no server: your data stays on your phone.
FASTING TIMER
• Plans 12:12, 13:11, 14:10, 16:8, 18:6, 20:4 and OMAD (one meal a day)
• From 12 hours to several days: quick picks 24, 36, 48 and 72 h, your own duration up to 7 days – or an open fast
• Multi-day fasts show "Day 3 of 5" with day marks on the ring; or switch to a 24-hour dial
• New to fasting? A gentle 6-week starter ramp from 12:12 to 16:8
• Large ring; one tap switches between time elapsed and time left
• Started earlier? Pick your real start time – or plan a fast ahead
• Change your goal mid-fast, end early or discard a fast
NOTIFICATIONS AND REMINDERS
• Ongoing notification with a countdown to your goal – even on the lock screen
• Alert with sound when your fasting goal is reached
• Weekly plan: a reminder to start fasting per weekday with its own time and plan – or following the sun; templates such as 2 × 24 h a week
• Optional heads-up 1 h before your goal and after hours you choose (e.g. 12 and 20 h)
• Eating window after your fast with time left, optional heads-up 30 minutes before it ends
• Android 16: the running fast as a live update in the status bar and on the lock screen
• Optional weekly summary, weekly weigh-in reminder and gentle come-back hints (all off by default)
• Automatic if you like: keep fasting after the eating window or start by your weekly plan
• Reminder to drink at your chosen interval, with quiet hours at night
HISTORY AND STREAKS
• Calendar of all fasting days: goal reached or ended early; day start of your choice for night shifts
• Current and best streak, averages for the last 7 and 30 days
• Charts for 7 days, 30 days and a year overview
• Mood and notes – also during a fast, shown as dots on the ring
• Pause days: a planned day off doesn't break your streak
• Optional weekly goal, badges for milestones and insights from your own records
• Edit start and end any time, add fasts you forgot to track
JOURNAL (OPTIONAL)
• Log water with one tap (and undo a mis-tap), with an optional daily goal (ml or fl oz); tea and coffee logged separately
• Log your weight with a 90-day chart (kg, lb or stone)
• Body measurements: waist, hips, chest, thigh, upper arm
• Optional Health Connect: share weight and water, take them over from other apps
KNOWLEDGE, WIDGET, EXPORT AND BACKUP
• Knowledge: calm, general notes on fasting, optional daily tip
• Home screen widgets: live countdown with start and end buttons, a 1×1 ring, plus water and weight widgets
• Quick Settings tile and shortcuts on the app icon
• Wear OS: watch app, tile with a live countdown and watch face complications – free
• Export all your data as CSV (Excel, Numbers, Google Sheets)
• Bring your history from other apps (CSV or JSON)
• Automatic backup to a folder of your choice
• New phone? Android backup or import the file – no account
FAIR, NOT A SUBSCRIPTION
Many fasting apps lock plans, statistics or export behind subscriptions. Fastivo doesn't: every feature is free, with no time limit. A small banner at the bottom edge supports the app – never above inputs or in dialogs, no full-screen ads.
PRIVACY
• No account, no sign-in, no server of our own
• No analytics; ads only after your consent
• Light, dark, pure black, dynamic colors and accent colors
• TalkBack, large text, tablets, landscape
• Available in 30 languages
IMPORTANT
Fastivo is a timer and log for your fasting times. It is not a medical device and does not replace medical advice. The app gives no diet or weight-loss advice. Children and teenagers, people who are pregnant or breastfeeding and people with a current or past eating disorder should not fast without medical guidance. If you have diabetes, take regular medication or have another medical condition, talk to your doctor first.
Novedades
New: a calm Knowledge section (hour by hour, when it gets hard, what breaks a fast), an optional daily tip, tea and coffee logged separately from water, difficulty dots and example eating windows for plans, import of files with start and end times (CSV or JSON), and a rate link under About. Still free, no subscription, no account, no pop-ups.
