About

Exercise Tracker

Features
Read full description

Ten push-ups is exercise. Log it in five seconds and keep your streak alive. Bite-Sized Exercise is free to start and free to keep, with no cap on logging and no trial clock. Bite-Sized Pro is an optional upgrade, and you never need it to log an exercise. Most fitness apps are built around workouts you schedule and finish. The squats you did waiting for the kettle fit none of them, so they go unrecorded. This app records them, then gives you a reason to come back tomorrow. ONE REP COUNTS There is no minimum worth logging. Ten push-ups by the desk, a two-minute walk, a few lunges while the pasta boils - all of it counts, and all of it feeds the same streak. THE STREAK IS THE PRODUCT Log something, any day, and the number goes up. Miss a day and it does not. The streak is the reason you do the second week, and it is the most important thing on the screen. STREAK FREEZES FOR REAL LIFE Life happens, and one bad Tuesday should not erase two months. Spend your points on a streak freeze and switch it on for today when you know you will not make it. With Pro, a held freeze can spend itself on a day you missed, and a streak that broke while you were away can be reconnected. LOGGING IN SECONDS, NOT MINUTES Open, tap, done. Counted exercises log against your daily goal with one thumb, and timed ones get a real stopwatch with a lead-in countdown. WALKS THAT LOG IN ONE TAP Part of Pro on iPhone: the app can spot a walk of ten minutes or more, counted by your phone's own motion sensor, and offer to log it. One tap and the minutes go into the exercise you choose. It is off until you turn it on, reads only today while the app is open, never leaves your phone, and logs nothing unless you tap. TRACK WHAT YOU ACTUALLY DO Track any three of Push-ups, Pull-ups, Squats, Lunges, Sit-ups and Walking at a time, free. Pro lifts the limit and lets you build your own, with its own icon, goal and unit - reps, seconds, minutes or hours. Set a weekly target in days, not hours, because showing up is what matters. POINTS AND TROPHIES Every log earns points, and points buy streak freezes. Seventeen trophies mark the milestones that mean something: your first exercise, a week, a month, a hundred days, a year. REMINDERS THAT RESPECT YOUR EVENING A daily nudge at the time you pick, silenced during the quiet hours you set, and never on a day you have already logged. YOUR DATA IS YOURS Your history stays on your phone. With Pro, you can also export all of it and keep your own copy. BITE-SIZED PRO Pro is optional and adds streak insurance, unlimited and custom exercise types, walk detection on iPhone, and data export. It is sold as an auto-renewing subscription or as a one-time purchase that never renews, and there is no free trial. The price for your region is shown in the App Store and in the app before you pay. A subscription is charged to your Apple ID at confirmation of purchase. It renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period, and renewal is charged within 24 hours before the period ends. Manage or cancel it any time in Settings, your name, Subscriptions. A one-time purchase has nothing to cancel. PRIVACY Your exercises, streak, points and trophies are stored on your device and are never sent to us or to anyone else. There is no account and no sign-in. Three things use the network: a check of whether you have Pro (RevenueCat keeps any purchase record under a random anonymous ID), anonymous usage counts, and crash reports. The last two follow one switch in Settings, Share anonymous usage data, which you can turn off. None of them carries your exercises or anything that identifies you. No ads, ever.
