Awful app
If you want to find yourself in a stressful situation, download this app. First, they offer a free trial, but they require you to unlock it and don't give you the opportunity to start the classes. When you are finally ready to pay and start, they only let you watch a video describing the chosen course a week later. They don't answer in the support chat. In general, the app is not automated, and I wasted a lot of nerves on it. Maybe it's a glitch? It seems like everything should be automatic? At least, I haven't encountered such idiocy in other apps.
