Udemy itself is a great service, and I watch videos on my laptop nearly every day. However, I've found the app to be fairly inconvenient to use compared with the website, and, most of the time, I need a computer handy anyway. But the app keeps sending out annoying reminders. Today's alert read, "Did you go off track?" I couldn't find a way to turn this feature off, so I finally uninstalled the app.
