I logged into Binance with my iPhone and iPad and it just does not fully work no matter what I do.
When I used to fool around with trading on Yobit (not recommended these days), I would often place orders while out for a walk in my neighborhood, and it was very easy to do it. Then again, I had no use for a lot of the graphical trading tools, which wouldn't look so hot on a tiny smartphone. Ultimately, whatever you choose should work just fine for you. My computer eventually bit the dust because it was old, but Binance was still fully functional when I used that PC to access their site. Good luck.
