What it does without asking
Built to stay out of your way.
- 01
Set it down. Walk away.
The screen stays lit the whole workout, so every beep and buzz lands without you waking the phone or tapping a thing.
- 02
Plays nice with your music.
Spotify, podcasts, whatever. Our cues mix on top. No ducking, no fade-out.
- 03
Save unlimited presets.
Build a 40/20/8/3 once. It’s there forever. No account, no cloud, no upsell.
- 04
No ads. Not now, not ever.
You don’t need a paywall to remove ads we never put there.
Why it’s free.
Our footer reads: time is the unit.
The timer is the literal expression of that. Charging for it would be charging for the unit. So we don’t.
What everyone else does.
No shade. Just the room we’re in.
