CPR Pacer: Live Rate Coach
Compression rate feedback
Free · In-App Purchases
Every session is logged and charted against the 100-120 guideline band - so you can see where you drifted, not just that you did.
Built for training and debriefs.
CPR Pacer holds chest compressions at the rate published in adult basic-life-support guidelines - 100 to 120 per minute - and tells you when you drift off it.
Tap the heart. It sounds a steady beat, taps the rhythm into your hand, and pulses on screen. Set the phone down where it can feel you working and it measures your actual tempo, then tells you to push faster, push slower, or keep going.
TRAIN WITH THE RECORD, NOT JUST THE RHYTHM
CPR Pacer keeps a log of what you actually did.
Every session is saved with its times, rate, compression count and rescuer cycles. Open one and you get a chart of your measured rate across the whole session, drawn against the 100-120 guideline band - so you see the shape of your performance, not just a score. Did you start ragged and settle? Hold a good pace and tire at the two-minute mark? That is the part a single percentage cannot tell you, and it is exactly what makes a debrief worth having.
Share any session as text with a trainer, a colleague, or a medical team.
FOR THE MOMENT IT MATTERS
- An audible beat that keeps sounding with the ring switch silent, the screen off, or the phone in a pocket
- A haptic tap on every compression
- A two-minute rescuer cycle timer with a swap prompt, so nobody works past the point where compression quality falls away
- Your location on screen as a street address and coordinates, ready to read to a dispatcher, and shareable in one tap
- One-tap dialling of your region's emergency number
- A plain-language cardiac arrest guide, with every figure traced to its published source
WHAT PRO ADDS
The compression rhythm, the live pace coaching, the guide, your location and the emergency call button are free, permanently, whether or not you ever buy anything.
Pro adds what is useful after the emergency, or outside one entirely:
- Session history, with the performance chart
- Session export
- A calm 70 bpm resting heartbeat
Try Pro free for 14 days. One purchase, yours for good. No subscription.
PRIVACY
Everything stays on your device. No account, no tracking, no analytics. Your location is shown so that you can pass it on yourself; the app never transmits it anywhere.
IMPORTANT
CPR Pacer is a training aid and timing reference. It is not a medical device, it does not measure compression depth, and it does not replace certified CPR training or the emergency services. In an emergency, call your local emergency number first.
