SwimPaceTimer
Read full descriptionHide full description
SwimPaceTimer is an Apple Watch interval timer for the pool. Three settings, that's it: distance, reps, and your send-off cycle. MADE FOR SWIMMERS WHO - are tired of watching the pace clock and counting in their head - just want to hold a send-off without fiddling with settings mid-set WHAT IT DOES - Build a set: distance x reps x send-off cycle (e.g. 25yd x 5 @ 1:30) - Tap start, get 5 seconds on the wall, then push off on the buzz - A heads-up buzz 5 seconds out, then a start buzz - hold your cycle without looking at your wrist - Countdown ring, rep dots, heart rate, split and total time at a glance - Live heart rate on screen while you swim WORKS ALONGSIDE THE WORKOUT APP SwimPaceTimer is a send-off timer, not a tracker. It never takes over a workout you are already recording. Start a pool swim in the built-in Workout app if you want it saved to Health โ that also turns on Water Lock for you โ then let SwimPaceTimer handle the send-offs. BUILT FOR THE WATER Screens are hard to read and harder to tap when you're wet. Set everything on the wall before you push off, then swim - your wrist tells you when to go. Yards or meters follows your region automatically.
