Cadence Keeper: Run Metronome

Cadence Keeper is a free, dead-simple cadence metronome for runners, cyclists, and anyone training to a tempo. Dial in a target BPM (40–240), hit play, pocket the phone. The click sits on top of your music at full volume and keeps ticking with the screen locked — so you can hold your stride or pedal cadence without thinking about it. Drive it from anywhere — every surface stays in sync, so you never wonder which one is right. • Apple Watch app — big BPM readout, Digital Crown to dial the tempo, ±1 buttons, play/pause. Let the phone play the click, or leave the phone at home and play it on the watch, up to an hour at a time. • Smart Stack widget on Apple Watch — current BPM and play/pause at a glance. • Home Screen widget — small shows current BPM at a glance; medium adds tap-to-control ± and play/pause right from the home screen. • Lock Screen Live Activity — bump the BPM or pause without unlocking. • Dynamic Island — same controls, one tap away. • Control Center toggle — start and stop without ever opening the app. The icon flips to a pause state while playing so you can see what's going on. Great for: • Runners working on stride rate (~170–185 spm is the usual target) • Cyclists holding a steady pedal cadence on climbs or flats • Rowing, jump rope, lifting tempo work — anything tempo-driven • Coaches who want a no-fuss beat for drills • Anyone tired of metronome apps cluttered with subscriptions and modes What you get: • Sample-accurate tick that stays locked over long sessions — no drift • Plays over your music at full volume, with the screen locked • Slider + ± buttons for quick BPM changes • Twelve tick sounds — Click, Beep, Clap, Clave, Drum, Tock and more — swapped mid-run without losing the beat • Works fully offline — no account, no feed, no subscription Free to download — no subscription, no account. Set it. Pocket it. Run.
