One of the applications that has proven to be useful to me is the Audionote app. I'm very happy of this purchase. I use it when I attend conferences or meetings. When I attend meetings, I just leave it recording. It allows me to freely listen without worrying of missing any information. It frees me from writing while listening. It also frees me from overthinking too much. What I like about it most is the fact that I can upload my notes to Dropbox or my iCloud Drive. That way, I am not limited with my iPad device's memory.
