SwimTempo

SwimTempo とは？

SwimTempo is a free tool for swimmers who want to hold a consistent pace in the pool. You choose a voice, metronome sound, pace, and distance, then generate a custom audio track for waterproof headphones. Each interval can be announced by voice, so you don’t need to count lengths yourself. You can also add background music or a podcast to make longer swims less monotonous.
