I use both the website and the app simultaneously (the latter is very well done). It's convenient, fast, and the courses are quite reasonable (I compared them with exchanges). Additionally, the wallet itself essentially acts as a mini-exchange where you can try trading. I've done this a few times and successfully, although I wish there were oscillators. It's nice that there's an option to exchange for fiat and withdraw to a card. As for downsides, I can mention the withdrawal limits per day, but I haven't exceeded them yet, so it's not significant.
