- 💰 Revenue: Modest — $3K - $7K/mo · MID tier · medium confidence, trajectory unclear.
- ⭐ Quality: 3.72★ across 75 reviews — weak — significant quality concerns.
- 📍 Market: Not yet charting in any of the 9 monitored markets.
- 📈 Growth: ⚠ last update 3106d ago — possibly dormant.
- ⚠️ Risk: Moderate — dormant (3106d since update).
🎯 For competitors: Mixed picture. Worth competing if you have a clear UX or pricing edge — otherwise crowded segment.
💵 For acquirers: Estimated asking range 18-32× monthly = $90K-$160K. Portfolio play ($9K/mo combined) commands premium.

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
📝 About this app
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.… View full description on the official store →
