Device(s) App Was Tested On:
This app, I have found, is actually quite accessible. There are a few buttons that aren't clearly labeled, but they don't seem that significant to the operation of the app. Also, sometimes the labeling of the interface can be slightly confusing, but, again, nothing major. In the Hearing Test portion, you may want to turn off VoiceOver before doing it because you have to turn the volume all the way up and you need to respond to the sound pretty quickly (the button to press is very near the bottom of the screen and is very easy to activate without VoiceOver). Also, unofrunately, when you turn the aid volume up, VoiceOver volume seems to go up as well, so it might be a good idea at least to turn off speech when using this app.
This app is good for DeafBlind users either with minor hearing loss who don't need a hearing aid all the time or only need it in specific situations. It is also good for DeafBlind people who simply may not have the funds for a traditional hearing aid.
