Really great app
I work with a blindness non-profit. There were discussions recently about creating an app with this exact functionality for people who are discovering VoiceOver for the first time and needing a lot of practice with feedback. I was thrilled to find out that such an app already exists. There were some small challenges in getting the app to recognise four-finger gestures, as most of the time only three fingers would get recorded. But apart from this, the app worked flawlessly for me.
