TBT Interval Timer

TBT Interval Timer is a simple, ad-free interval timer for workouts, training, stretching, and repeat routines.

Set your warm-up time, work time, rest time, and number of sets. The timer shows the current phase, the next phase, total time, and remaining time in a clear full-screen layout.

The app keeps the screen awake while the timer is running, so you can follow your intervals without the display auto-locking.

Features:

• Ad-free experience
• Keeps the screen awake while running
• Custom warm-up, work, and rest durations
• Custom number of sets
• Clear WORK, REST, WARM UP, and FINISHED phases
• Circular progress display
• Total workout time display
• Sound and vibration toggles
• Simple controls for start, pause, reset, and settings

Use it for Tabata, HIIT, circuit training, stretching, boxing rounds, bodyweight workouts, or any routine that repeats work and rest intervals.
