Train anywhere — on iPhone, Apple Watch, and Android. Voice cues, offline support, and the same workouts you know from the web.
Train anywhere — on iPhone, Apple Watch, and Android. Voice cues, offline support, and the same workouts you know from the web.
HIIT, Tabata, EMOM, circuits, and anything you can dream up. Mix intervals, sets, and rounds without leaving the app.
Voice cues call your intervals out loud. Keep your eyes on the bar, the bag, or the gym floor.
Run your playlist alongside the timer. Cues duck the music; your playlist plays the rest of the time.
Run on iPhone, Apple Watch, or Android. Workouts you build on one device are ready on the others.
Send a timer to a friend in one tap. Color-code every interval so you know what is coming before the beep.
Big tap targets, screen-on lock, background playback. No account, no ads, no friction.

From phone to watch, every screen in Seconds is built for the moment you actually need it — mid-rep, mid-rest, eyes down, hands busy.
Seconds has been used aboard the International Space Station. How many interval timers can say that?
