📝 About this app
EP Calipers provides electronic calipers to measure intervals on images of electrocardiograms (ECGs) or electrophysiologic recordings. Doctors, nurses and medical technicians photograph and send ECGs to each other via email and messaging using smart phones and tablets. It is difficult and inaccurate to make measurements on these images with mechanical calipers. EP Calipers can be used to make accurate ECG measurements and do calculations such as determining mean heart rate and corrected QT interval. Angles such as the beta angle in Brugada syndrome can be measured as well. Analyze ECG images you photograph or store on your device, as well as PDF files, such as ECGs generated by the AliveCor Kardia™ device.

🌍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.
