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. ### 1/5 — FEV1 is where graphed? *2025-08-28, version 2.2.4* Download record FEV1 each reading but does not chart. Having COPD FEV1 is more relevant than PEF ALSO NO INFO as to where to get a download that includes charting FEV1 so far therefore no reason to be pleased with purchade ### 5/5 — Works perfectly *2024-03-30* Connected from my iPhone to the sonmol PEF easily. It records any data since the last recording and appears to be accurate. ### 1/5 — Useless app, useless device *2024-03-11* Does not sync with device. Device also does not save date (which could also be done by sync). Is it even accurate? Who knows! ### 2/5 — Not on iPhone health app *2024-01-05* Information does not sink to health app ### 1/5 — Quit working on third day *2023-11-01* Seemed ok for first two days. Then it seemed unable to sync with peak flow meter. It has become useless ### 3/5 — Could be better. *2023-06-30, version 1.1.6* A good app could be great if you included read/write access to Apple Health. There’s not much point in having an electronic peak flow meter, with its own app, when you then have to manually add the data into the Health app. ### 5/5 — This helped me to view how my lung works in the last month *2023-05-30* This is the only application that I used for free and in the same time, shows me a diary of my peak flow in both picture and form. It’s great for me. ### 1/5 — No iOS Health Integration *2023-05-10* I have never used something like this to track breathing. I wish this app would integrate with the Apple Health app. ### 1/5 — Can’t create password *2023-03-17* 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. ## Frequently asked questions about ePEF ### Does ePEF require a peak flow meter? Yes, ePEF is exclusively designed to work with a Digital Peak Flow Meter.
