The engine
Built on the clock,
not a counter.
Most timers tick down a number and quietly lose seconds. timerkit reads the wall clock on every frame, so a five-minute round is five minutes — pause it, background it, take a call. It picks up exactly where it left off.
No drift

Everything in one timer
The details that make intervals actually usable.
A long rest between rounds
Between rounds you get a separate, longer rest — never the short between-set one. The last round has none: the workout ends the moment your final set does.
Spoken countdown
Every round and set called out, a heads-up at 10 seconds on longer intervals, and a clear 3-2-1 to close each one — heard over your music and through the mute switch.
Save many, color-tag each
Build a library of named timers — HIIT, mobility, breath work — and tag each with one of eight colors. Tap a swatch to retint the demo.
Screen stays awake
During a run the display won't dim and your music keeps playing — ducked gently under each cue, never stopped.
Sets, rounds, finish
Sets build a round. Rounds build the workout.

Common questions
Yes. timerkit ducks other audio for each spoken cue, then restores it — and cues are heard even with the mute switch on, so you never miss a transition.
The timer is driven by the wall clock, not a counter, so it never drifts. The screen is also kept awake during an active workout so you can glance down anytime.
Absolutely. Keep a whole library of named timers, each with its own work, rest, sets per round, rounds, long rest, narration setting, and color tag.
Yes — narration is a per-timer toggle. Leave it on for guided sessions, switch it off for a silent run.
