CPR Tempo downloads
Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.
Active users
All platforms, worldwide. Free with an account.
Stickiness (DAU / MAU)
how many monthly users open it on a given day
How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

Review momentum
20/100
faster than 0% of Medical apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About 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.
