Triple B Development
Small apps, built to be used.
I design and build focused, no-nonsense apps — starting with Sprint Intervals, an interval timer for runners who don't need another bloated fitness platform.
Featured App
Sprint Intervals
A simple, distraction-free interval timer built for sprint and speed training. Set your work and rest intervals, hit start, and go — no account, no clutter, no subscription wall.
- Custom work / rest intervals and round counts
- Audio and haptic cues, screen-off support
- Built for the track, the road, or the gym
Simple by default
Every app does one thing well. No feature bloat, no clutter, no unnecessary sign-ups.
Privacy-first
Your data stays on your device wherever possible. Nothing is sold, ever.
Actively maintained
Built and supported by one developer who actually uses the apps.
More apps in the works.
Sprint Intervals is the first. It won't be the last.
