This is it!
Look no further for a hearing test app for audiogram and data! If you're in for OTC hearing aids etc etc then JacotiHearingCentre (JHC) app is it (and free too)! The app integrates with Apple's Health app for data storage and retrieval (also via the web by the way). The ability of the thorough app to test my poor hearing is useful to me, and recommended it to friends. Pure tone tests span 125Hz through to 12000Hz noting that from 8000Hz I get the value 85dBHL, meaning I am deaf there. The app gave me urgent advice to see my Audiologist soon (done that years ago)! The app is not difficult to use. Try and you get the hang of it soon. Use a quiet room testing it with the free NIOSH app "as-is" (I aim at 30-33dBA). The JHC app needs registering, with email confirmation - no problem. A small price for excellent info. My equipment is iPhone SE 2022, and AirPods 2nd Gen. Search for Jacoti on WWW for info about app's background and company credentials. Impressive.
