Tempo is a habit tracker with a focus timer built in. Tick off the small things as you go. When something needs real attention, tap it and a session starts with a countdown that keeps running on your Lock Screen. Everything you complete fills in the same progression grid of squares. TWO KINDS OF HABIT Some take a second. Drink water. Take your vitamins. Others want real time set aside: thirty minutes of deep work, a twenty minute run. • Tick-off habits • Timed habits that open a focus session the moment you tap them • Choose the days of the week each habit runs on • 64 habit templates ready to go, covering health, study, finance, and more. • Rough week? Pause a habit and come back to it. Your history stays exactly where it was. REMINDERS Ensure you do not miss a completion by setting reminders. Each habit can carry its own reminder. You can also switch on a daily check-in reminder, with your own time and message. THE FOCUS TIMER Tap a timed habit and the rest of the app gets out of the way. Eleven sounds to sit behind your work: rain, heavy rain, storm, ocean, forest, campfire, wind, stream, birds, a night field and a ticking clock. Keep the screen awake if you like watching the numbers drop, or lock the phone and follow the countdown from your Lock Screen. TRACK YOUR IMPROVEMENTS • Streaks, and a progression grid of little squares that fill in as you progress • Weekly, monthly and yearly views • The hours of the day you tend to show up • A journal of every session you finished, including its date and time MAKE IT LOOK RIGHT • Over 30 backgrounds. Set some of your favourite cities and natural scenery as backgrounds. • Light and dark, with habit cards that you can make as see-through as you like • Reorder your habits, hide the finished ones, hide the habits on days you are off • Home Screen widgets to show today's list without opening the app • 12 languages WHERE YOUR DATA SITS Your habits are stored on your phone. There is no Tempo account and no servers. Switch on iCloud sync and the backup goes to your own private iCloud. --- Terms of Use: https://tempohabit.app/terms/ Privacy Policy: https://tempohabit.app/privacy/
