Sthira: Yoga Interval Timer

A two-phase interval timer for yoga, built around one idea: you practise with your eyes closed, so the timer has to be heard, not watched.

Each phase ends with its own sound. A single bright tone when a hold finishes. A rising three-note figure when the rest is over, long enough that you can begin moving into the next posture on the rise. You never look down, and you always know where you are.

HOW IT WORKS Set your hold, set your rest, set the number of rounds. Press begin. That is the whole app.

ON YOUR WRIST The Apple Watch app runs on its own, with the phone in another room. Every cue is paired with a distinct haptic, so a practice works in complete silence — in a shared room, or a sleeping house.

BUILT TO STAY OUT OF THE WAY • Keeps running with the screen locked and the phone in your pocket • Screen stays awake through a session, readable from a mat at arm's length • Skip a phase when a posture finishes early • Save the practices you repeat and start them in one tap • No account, no cloud, no sign-in

HONEST PRICING The timer, every sound and every haptic are free, forever. One optional payment of $0.99 unlocks the Watch app, unlimited saved practices, and your streak and history. No subscription. It is finished software.
