Building the future of swim pace training
We're swimmers and coaches who got tired of outdated tempo trainers. So we built a better one.
The problem we're solving
We've been there. As swimmers and coaches ourselves, we know the frustrations:
No firmware updates
Traditional beepers are frozen in time. Bugs stay forever, features never improve.
Single beep only
One sound, one feedback mode. Hard to hear underwater, impossible to customize.
No programmable intervals
Want a structured tempo workout? Good luck programming that on a 3-button device.
Our approach
Triple feedback
Audio + haptic vibration + visual OLED display. You'll never miss a beat.
Bluetooth updates
We ship firmware improvements regularly. Your device gets better over time.
Custom programs
Build complex interval workouts via the app. Sync wirelessly, train smarter.

How we work
Swimmer-first design
We prototype in the pool and listen to coaches early.
Precision & clarity
Tempo should be obvious, predictable, and easy to trust.
Continuous iteration
We ship updates and improve quickly with user feedback.
