TargetSplits helps rowers work out the split they need to hold for an erg test. Existing calculators were dated, fiddly on a phone and didn’t help with pacing strategy, so I built one that does the single job well.
It started as a personal challenge to improve on the traditional tools and to experiment with AI-assisted code generation. It reached 3,700 users in under three months with no marketing beyond the rowing community passing it around.
Design
- One calculation, front and centre, with results updating as you type or swipe.
- Mobile first, because it gets used next to an erg.
- No accounts, no dependencies, loads instantly.
