## What is CPR Tempo?

CPR Tempo provides audio and visual cues to aid the timing of chest compressions during cardiopulmonary resuscitation (CPR). Timers are also provided for rhythm checks after defibrillator shocking and for epinephrine administration.

The American Heart Association recommends a rate of 100 compressions per minute during CPR. This is difficult to maintain without audio cues, especially as the rescuer tires. ER nurse and Army Reservist MAJ Don Kyle shared with Frozen Ape about our metronome app Tempo is being used for this purpose. We have since worked with Don to create a specialised app, including the following bonus features:

- Timer with visual and audio cues for rhythm checks
- Timer with visual and audio cues for Epinephrine administration
- Log of each resuscitation event detailing each action taken and location of event (location services required)
- Configurable CPM (compressions per minute) from 100 to 120
- Configurable epinephrine interval from 3 to 5 minutes

Disclaimer: This app follows standards recommended by the American Heart Association. Do not use this app if these standards do not align with your medical practice. Please familiarize yourself with this app, including the tutorial, and verify the settings before using the app in an actual resuscitation event. Frozen Ape Pte. Ltd. is not liable for mishaps due to the misuse of, or malfunctioning of the app.

## Key features

- Audio and visual CPR compression timing cues
- Rhythm check timer
- Epinephrine administration timer
- Resuscitation event logging
- Configurable compressions per minute (100-120)
- Configurable epinephrine interval (3-5 minutes)

### 1/5 — Weird sound

*2026-01-23*

I used to love this app but now it has a weird scratchy noise after every beat. It has become a distraction so I’ve quit using it on codes. I’ve tried updating. It has happened on two devices. Otherwise it was a great app

### 5/5 — Amazing!!

*2025-10-24, version 1.2*

Every EMT should have this app installed in case you need it.

Just used it last night on a code.

Really helped the crew..

### 1/5 — Amateurish

*2025-07-25*

Every metronome chirp is followed by a burst of static. The defibrillator/rhythm check button isn’t logically named as each check doesn’t prompt a shock. Neither the rhythm check nor epinephrine counters provide an audible signal.

### 2/5 — Falling quality

*2025-07-10*

Have you used this for years and it has been fantastic. However now there is a terrible noise with the metronome I’m unable to fix, and every other user I know has the same issues.

### 2/5 — Sound

*2025-05-12*

Please fix the sound so it’s not scratchy. It’s sounds like a blown speaker and is very distracting and easy to get off beat with the secondary sound. It makes the app seem faulty.

### 3/5 — Fuzzy sound?

*2025-04-04*

Very helpful app but it’s making a fuzzy sound with each tone. I thought it was my phone. It’s the app. Why?

### 2/5 — Used to be great

*2025-02-22*

Used this app for years to assist with CPR and has been great. The latest update has caused a static sound with the metronome that is terrible. Please fix this soon.

### 2/5 — iOSアップデート後から？

*2025-02-02*

ノイズが入るようになって使えなくなった

### 2/5 — Used to be great

*2025-01-30*

This app used to be great. Now it has this awful alarm buzzing sound as well as the metronome.

### 3/5 — Was a great app

*2025-01-27*

Was a great app, but new update has a weird buggy sound in the background. Confusing for students. Bring it back to what it use to be.
