Fast your bad habits away.
Doomscrolling. Vaping. 2 a.m. snacks. Habifast puts them on a clock instead of a guilt trip — start a fast, stack a streak, and let the AI coach do the nagging.
Three steps. No shame spiral.
Add it as a bad habit with an emoji, a schedule and a reminder. Good habits and counters work the same way.
Pick a preset from 16:8 up to 72 hours, or set your own end time. The timer keeps running overnight — midnight doesn't reset you.
Every hour held out pays points — even a partial fast counts. Miss a day and vacation mode or a streak shield keeps the fire alive.
Every fast has phases. The app walks you through them.
As the clock runs, Habifast tells you what is happening in your head — and pushes a notification the moment you hit the next phase.
Choosing to pause a habit already fires up your prefrontal cortex — the part that runs self-control.
Every impulse you ride out weakens the neural link behind the habit. That is habit reversal in action.
Sugar and social media flood your brain with dopamine. A few hours off and your sensitivity starts to normalise.
Without constant stimulus the mental noise drops. This is where most people notice sharper focus.
Your brain wants a replacement. Now is the moment to anchor one — a walk instead of a scroll, water instead of a snack.
Halfway. You are proving to yourself that you run the habit, not the other way round.
Sixteen hours. Each successful pause weakens the automatic trigger a little more.
A full day clean. Every further cycle cements the new version of you.
Everything you need to break a habit — and nothing else.
Presets from 16:8 to 72 h, custom durations, fixed end times and partial points for partial wins.
Daily goals with real units — litres, pages, reps — plus per-weekday schedules and “up next today”.
Chat with a coach that has your streak, fasts and misses in front of it. Straight answers, no horoscope.
Your streak counts on any real use of the app. Going away? Vacation mode protects it. Bad day? Spend a shield.
Fast timer, active timer and a daily overview widget — check in without opening the app.
Block the apps that set you off while a fast is running. The block screen tells you how long you've got left.
The whole app, no surprises
Five tabs, one bottom bar, everything two taps away. Light and dark theme, both shipping.
Bad habits, good habits and counters — each with its own schedule.
A month at a glance with the week schedule underneath. Tap any day to fix your history.
Spend points on streak shields, vacation mode and second chances.
Streak, points, shields, reminders, theme and language in one place.
Quit in nine languages
Habifast follows your phone's language automatically — every screen, every notification, every coach reply. Switch it by hand any time in Profile.
Nagging, but only when it counts
Habifast does not spam you at 9 a.m. with a list. It pings when a fast is about to start, when you cross a phase, and when a streak is on the line — and stays quiet the rest of the day.
Start free. Upgrade when the free plan starts annoying you.
Pro pricing is shown in the app. No account needed to start.
Questions before you quit something
What does “fasting” mean here? +
Not just food. A fast is any window in which you avoid something — sugar, nicotine, social media, alcohol, gaming. You set the duration and the end time; Habifast runs the clock and pays out points for the hours you hold.
Is Habifast free? +
Yes. The free plan covers 5 habits, one active timer, 30 days of history, one AI coach question a day and App Guard for one app. Pro lifts every limit: unlimited habits and timers, the 365-day analysis, the unlimited AI coach, multiple fasting plans and App Guard for every app.
Where does my data live? +
Your habits, timers and points are stored locally on your device. Only what you send to the AI coach leaves your phone, through our own proxy. Details are in the privacy policy.
Is there an iPhone version? +
Android first — Habifast is on Google Play today. iOS is on the roadmap; the app itself is already built as a web app, so the port is next in line.
Which languages? +
Nine: German, English, Spanish, French, Portuguese, Italian, Chinese, Japanese and Korean. The app follows your phone's language automatically, and you can override it in Profile.
