This app is perfect for audiophiles. Adjusting the variables for each frequency can be tedious and time consuming but once it’s done, my AirPods sound insanely good. I’m a classical music kind of guy and Apple’s algorithm doesn't seem like it’s designed for classical music. The one downside is that you can’t play music while adjusting the frequencies because Apple doesn’t allow that. I talked to the developer and he can’t do anything until Apple allows that kind of integration. Oh well.

I was thrilled to find a way to enter my audiogram data into the Health app but kind of sad that I couldn’t back-date my entries on the version that I originally downloaded. (New entries would only post to the date that I entered them.) I took a chance and emailed the developer, Tom, to ask if this feature could be added. He emailed me within a day and said that he would look into adding this feature. Today, less than a week later, Tom has posted an update with the date functionality that I asked for! Thank you, Tom!, I appreciate your fast response and quick work! :)

This app allows you to enter your own audiogram in HealthKit, thereby customizing the sound of AirPods. This is the only app that allows direct input like this. Even if you don’t have hearing loss, this app will allow sophisticated custom equalization of your AirPods. Want your AirPods to have a bit more mids, or just tweak on frequency? This is your app and as far as I know the only way to do this.
