The cleanest HIIT workout timer built for people who actually train.
Supports EMOM, Tabata, circuits, and custom interval formats. No fluff, no subscriptions. Just the timer you need.
Quiet, focused, and made with the same care as everything else from the studio.
Built with the same philosophy — do one thing, do it beautifully. Details coming when it's ready.
ANNR Studio is a personal laboratory for mobile software. Not a team, not a VC-backed startup — just one developer with high standards and an obsession with craft.
Every app ships when it's ready. Every detail matters.
