Warm-up, main set, cool-down — type in the reps and it keeps the running total, works out your send-offs against the clock, and prints a sheet you can read on the pool deck. No login, no plan to follow. You write it, you swim it.
Start writing ↓Type your sets the way you'd write them on the board — 8 × 100 free on 1:40. The slip on the right keeps the running total.
Five sessions to begin from. Tap one and it drops into the builder — then change whatever you like.
Give it a recent time and it suggests a send-off for each effort, and marks where to leave on the clock.
Send-offs round up to a tidy interval and aim for ~5–15s rest. Tap a row to set the clock.
Most go warm-up, a short sharpener, the main set, then a cool-down. That's the whole shape — the rest is detail.
Easy swimming, a little kick and some drills to find your stroke. Usually 15–25% of the session, all low zones.
Short, sharp efforts — builds, descends or technique work — to bridge the gap before the main set. Optional, but it sharpens you.
The reason you got in: endurance, threshold or sprint work. Where the send-offs matter and most of the distance sits.
Easy, loose swimming to flush the legs and arms. A few hundred metres of recovery to finish — never skip it.
