Mobile Trading apps

Hi everyone, I’m new to trading and am wondering what the hype is about mt4 and mt5 trading on their charts is very difficult for me I am successful in trading view but I am with pu prime and can not connect my acc. with trading view what should I do? I scavenge trade mainly metals but I do GBPJPY and ethereum aswell so getting in and out with trading view is nice but I want to know a good reliable app with pu prime that I can link or should I just change my broker?
