The lane Log your OWN times and see your best, your average, your % improvement, and a season bar chart. The meet Race the coaches through pace, splits, conversions, cuts, and relay math — one move each.
Meet your coaches
Five little coaches read the clock with you — each one is one part of the ratio-&-percent maths.
- Split the Stopwatch — mixed-unit subtraction — the take-away between two clocks
- Pace the Penguin — the unit rate — your time shared out over every 100m
- Cut the Standard-Setter — the inequality — your time must be ≤ the qualifying cut
- Convert the Otter — yards ↔ metres — a yard is a little shorter than a metre
- Taper the Tortoise — the season graph — your best, your average, your improvement
🔒 SplitForge runs right here on your device. Your times are personal — they stay on THIS device only. There is no account, no ads, and no AI, and nothing you enter is sent anywhere.
