A focused first lap.
Our Wear OS prototype lets you choose a local workout and follow it through to completion with manual controls.

Advance lengths, skip rest, pause, resume, or end from the watch. Sensor tracking comes later.
02 / ON THE HORIZONBuilt to go
Built to go
the distance.
Our current focus is visual quality, accessibility, and testing across round watch sizes. The phone companion and web app now share an early cloud account. Later milestones include real swim tracking and watch sync.
We’ll mark each capability clearly as it ships. Accounts and a simple web planner are available for early testing. Watch sync and sensor analytics are still in development.
