Run/Walk Interval Timer & Couch to 5K
Follow the 8-week Couch to 5K plan with a voice that says 'Run!' and 'Walk' at the right moments, counts down the last seconds and tracks which days you have finished. Or build custom run/walk intervals, or let speed play (fartlek) surprise you with random bursts.
A warm-up and cool-down are built in, the screen stays on, and every session is logged.
