ABBURN — MINIMALIST TABATA & HIIT TIMER

Abburn is a no-nonsense interval timer for Tabata and HIIT training. Pure black and white, zero clutter, and big bold numbers you can read from across the room. Pick a workout, hit start, move.

GUIDED WORKOUTS • FAT BURNING — 10 high-intensity, no-equipment moves. • Every exercise shows a moving demo, its name, and what's coming up next during rest.

BUILD YOUR OWN • Assemble a custom workout from the full exercise library. • Add, reorder, and remove moves — your workout is saved for next time.

QUICK TIMER • Just want intervals? Set your own prepare, work, rest, and rounds. • Any durations you like — the classic 20/10 for 8 rounds by default.

BUILT FOR TRAINING • Sharp audio cues count you down (3-2-1) and signal every phase change. • The screen stays awake for your entire workout. • Dark and light themes. • Clean round-by-round progress you can track at a glance.

FREE & PRIVATE • Completely free — no ads, no subscriptions, no accounts. • No tracking, no analytics, works 100% offline. • Nothing you do ever leaves your device.

Whether you're squeezing in four minutes before work or grinding a full circuit, Abburn keeps it simple: your workout, your timer, your burn.

Always train within your limits and consult a health professional before starting any new exercise program.
