Everything a competitive swimmer needs.
Built for deck-side planning on Apple devices, with the same fast workflow swimmers and coaches need before a race.
Coefficient-Based Splits
Every split is calculated from real swim-meet pacing data — not a simple even split. Your 200 Free should go out differently than your 200 Fly.
Visual Split Bar
A proportional colour-coded bar shows instantly how your pace is distributed across each length of the race.
Save Targets per Swimmer
Store unlimited targets for each swimmer on your roster. Quickly reload any saved target into the calculator for a fast comparison.
PDF Export
Generate a clean, shareable PDF of any single target or all targets at once. Perfect for handing out at practice or sending to parents.
All Courses & Strokes
LCM (50m), SCM (25m), and SCY (25yd). Freestyle, Backstroke, Breaststroke, Butterfly, and Individual Medley across all standard distances.

Common questions about Swim Splits.
These are the questions swimmers and coaches usually ask before choosing a swim split calculator.
What does a swim split calculator actually do?
A swim split calculator converts a target finish time into clear pacing checkpoints for each length or lap of the race, so you can race with a plan instead of guessing your tempo mid-event.
Which courses and strokes are supported?
Swim Splits supports long course meters, short course meters, and short course yards across freestyle, backstroke, breaststroke, butterfly, and individual medley race formats.
Is Swim Splits only for coaches?
No. Competitive swimmers can use it for personal pacing targets, parents can follow race plans more easily, and coaches can save and organize targets for multiple swimmers.
Can I use Swim Splits at the pool without internet?
Yes. Swim Splits is built to work offline, so your saved targets and calculations are available at practice, during warmups, and on meet day without needing a connection.
Why use Swim Splits instead of doing the math manually?
Manual pacing math is slow and usually oversimplifies the race. Swim Splits uses event-specific pacing coefficients so the splits feel closer to how swimmers actually race different distances and strokes.
