Trash. I trusted this app for a month until I was halfway through my python core course (After my Golang course that had no problems at all) Then It just told me to give them $4 a month! That's 48 dollars a year! This is more expensive than a music distribution subscription! Do not get this. Whoever made this App please make sololearn full courses free, and just make Sololearn pro just a tiny upgrade. This has been a good experience, but Sololearn pro just ruined all of it. Edit: You Should also Make the Try It Yourself free.
