Interval Timer: Tabata & HIIT

Roundloft is an interval timer for Tabata, HIIT, EMOM and boxing rounds that keeps counting when your phone is locked, in a pocket or on the floor. Every cue arrives on time, so you can train without watching the screen.

Start in one tap
• Ready-made Tabata Classic, EMOM 10 and Boxing Rounds timers
• Quick start puts your last workout one tap away
• Build your own with work, rest and rounds, and see the total workout time update as you edit

Name every interval
• Give each step its own name, like Burpees or Plank, in the advanced editor
• The player shows what you are doing now and what comes next
• The total time left is always on screen

Hear it, feel it
• Beep, bell or whistle sounds, with countdown ticks before each change
• Optional voice cues read out the phase, the interval name and what is next
• Vibration on every phase change
• Your music keeps playing: it gets quieter during a cue instead of stopping

Built to keep running
• Keeps going with the screen off and survives the app being closed by the system
• Pause or resume from the notification
• A phone call pauses the workout, and hanging up resumes it
• Warns you if battery settings on your phone would stop the timer, and takes you to the fix

Made for training
• Large, high-contrast numbers you can read from across the room
• Colour and text change with every phase, so you never rely on colour alone
• Works in landscape and with TalkBack
• Keep the screen on during a workout if you want to

No account and no sign-up. Your timers stay on your phone. Roundloft is supported by ads, which never appear while a workout is running. One optional purchase removes them for good: a single payment, not a subscription, and you can restore it on a new phone.
