Whats your favourite apps on your phone?

Yeh I like to play on pubg it is the only game I have on my phone the rest are either social media or business related apart from that tho pubg does require the use of mobile data but its not so intense as fortnite I do like pubg mobile but I do find it very easy as every game I have played I get around 15-25 kills and allways come first and mobile players are not as good as pc and console players.
