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.

Pause or resume right from the lock-screen notification, no need to unlock.

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, or duck your music so the tick stands out
• Alternate ears — with headphones, the click leans left, then right, on each beat
• Slider and ± buttons for quick BPM changes
• Light and dark themes
• Works fully offline — no account, no feed, no subscription
