As necessary as an Oxygen Saturation finger tip meter and its app! You can .own both for about $100. ePEF has some shortcomings but my Pulmonologist was totally amazed. -- Bill of Eureka, 2025-09-28 ### ***** "Works perfectly" Connected from my iPhone to the sonmol PEF easily. It records any data since the last recording and appears to be accurate. -- Dennisfromhb, 2024-03-30 ### *---- "Useless app, useless device" Does not sync with device. Device also does not save date (which could also be done by sync). Is it even accurate? Who knows! -- Zoobee zoobee zoo, 2024-03-11 ### **--- "Not on iPhone health app" Information does not sink to health app -- MElai9, 2024-01-05 ### *---- "Quit working on third day" Seemed ok for first two days. Then it seemed unable to sync with peak flow meter. It has become useless -- hitvod, 2023-11-01 ### *---- "No iOS Health Integration" I have never used something like this to track breathing. I wish this app would integrate with the Apple Health app. -- jwa722, 2023-05-10 ### *---- "Can’t create password" I work in IT so I know how to create a password, but this app won’t allow me. It says password requires 6-16 digits and……. You can’t read the entire message. I have tried several different passwords. -- Zorba1213, 2023-03-17 ### ***-- "Getting there" I just started using your app and product. Could you get app to calculate the % range and know where you are per info you enter. Also a graph of the data would be great. -- poodlememe, 2022-10-12 [View all ePEF reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Apps Similar to ePEF - [NuWave Connect](https://apptail.io/app/nuwave-connect-NnN/united-states) - [BP Doctor](https://apptail.io/app/bp-doctor-Ksqc/united-states) - [PillCalendar](https://apptail.io/app/pillcalendar-ITmi/united-states) - [Meraw Health](https://apptail.io/app/meraw-health-jczj/united-states) - [TireMinder Lite](https://apptail.io/app/tireminder-lite-aonm/united-states) - [Air Oasis Home](https://apptail.io/app/air-oasis-home-VBcn/united-states) - [GMCMap](https://apptail.io/app/gmcmap-nGMn/united-states) - [eRMT](https://apptail.io/app/ermt-mamp/united-states) - [SereniBrain](https://apptail.io/app/serenibrain-ZTyt/united-states) - [Kanary: Safeguard your privacy](https://apptail.io/app/kanary-safeguard-your-privacy-AdWv/united-states) ## ePEF Available In - [Germany](https://apptail.io/app/epef-JXte/germany) - [United States](https://apptail.io/app/epef-JXte/united-states) - [Russia](https://apptail.io/app/epef-JXte/russia) - [Australia](https://apptail.io/app/epef-JXte/australia) - [United Kingdom](https://apptail.io/app/epef-JXte/united-kingdom) - [Netherlands](https://apptail.io/app/epef-JXte/netherlands) - [Dominican Republic](https://apptail.io/app/epef-JXte/dominican-republic) - [Algeria](https://apptail.io/app/epef-JXte/algeria) - [Ecuador](https://apptail.io/app/epef-JXte/ecuador) - [Spain](https://apptail.io/app/epef-JXte/spain) - [France](https://apptail.io/app/epef-JXte/france) - [Hong Kong SAR China](https://apptail.io/app/epef-JXte/hong-kong) - [Ireland](https://apptail.io/app/epef-JXte/ireland) - [Israel](https://apptail.io/app/epef-JXte/israel) - [India](https://apptail.io/app/epef-JXte/india) - [Italy](https://apptail.io/app/epef-JXte/italy) - [Kazakhstan](https://apptail.io/app/epef-JXte/kazakhstan) - [Mexico](https://apptail.io/app/epef-JXte/mexico) - [Nigeria](https://apptail.io/app/epef-JXte/nigeria) - [Norway](https://apptail.io/app/epef-JXte/norway) - [New Zealand](https://apptail.io/app/epef-JXte/new-zealand) - [Peru](https://apptail.io/app/epef-JXte/peru) - [Saudi Arabia](https://apptail.io/app/epef-JXte/saudi-arabia) - [South Africa](https://apptail.io/app/epef-JXte/south-africa) - [Canada](https://apptail.io/app/epef-JXte/canada) - [Switzerland](https://apptail.io/app/epef-JXte/switzerland) - [Chile](https://apptail.io/app/epef-JXte/chile) - [Czechia](https://apptail.io/app/epef-JXte/czechia) - [Denmark](https://apptail.io/app/epef-JXte/denmark) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
