Burnr

About Burnr

Burnr is a focused interval timer for HIIT, circuits, cardio, strength sessions, and any workout built around effort and recovery.
Set up your workout in seconds with warmup, work, rest, transition, repeats, and cooldown phases. Start the timer, follow the clear countdown, and let Burnr guide you through each interval with sound and vibration cues so you can stay focused on training instead of watching the clock.
Create workouts your way:
Build simple HIIT timers fast
Save your favorite workouts as presets
Use advanced workout building for circuits and custom exercise structures
Review completed sessions in workout history
Set workout reminders to help keep your routine consistent
Keep the screen awake during active sessions when you need it
Use audio and vibration alerts for phase changes
Burnr is designed for real training: garage workouts, gym sessions, home circuits, boxing rounds, running intervals, mobility blocks, stretching routines, and quick high-intensity sessions when you only have a few minutes.
Your workouts can stay local, or you can sign in to sync presets and history through the Burnr cloud. Google Sign-In, email login, and anonymous mode give you flexibility depending on how you want to train.
Whether you are doing a 4-minute Tabata, a 30-minute conditioning circuit, or a custom interval plan, Burnr gives you a clean timer, saved presets, reminders, and progress history in one place.
