STRDR

Run in sync — cadence coach

Free · Designed for iPad. Not verified for macOS.

Dial in your running cadence with a smart metronome, real-time coaching, and music matched to your steps. Run smoother, reduce injury risk, build your rhythm. Great runners share one secret: rhythm. STRDR turns cadence — the steps-per-minute that drives efficient, lower-injury running — into something you can actually feel, hear, and improve on every run. WHAT IT DOES Personalized cadence targets — dialed to your height, experience, age, and pace, not a generic 180. Sample-accurate metronome — a rock-steady click that keeps you on rhythm, survives a locked screen and pocketed phone, and layers over your music. Real-time coaching cues — spoken guidance and on-screen prompts through your workout, so you adjust without breaking stride. Cadence by distance — see your target cadence for 5K, 10K, half, and marathon, extrapolated from your own race times. Music that matches your steps — find songs from your Spotify library at your target BPM (or half-tempo, two steps per beat) so the beat IS your cadence. Runs in the background — full workout and audio while your phone's locked in your pocket. WHO IT'S FOR New runners building good habits. Injury-prone runners fixing overstriding. Experienced runners chasing efficiency. STRDR. Run in sync.
