Do you really, like realllllllllllllly need those apps? ;-) For me i only need Mezzages Phone calls All the basic tools that it would have And okay u caught me nowadays we use messaging apps like discord ehatsapp inimstagram telegram not just for chatting which can be done at home, but to get updates about something youte involved in andaybe its better to go not the whole day without receving those. But why have so many apps when you can just have beeper! You dont need (music streaming app) get a portable mp3 or/and a self hosted music streaming service! You dont need google maps - use a real life map! Or a lightweight offline map no gps?! You dong need banking app-pay with cash! you dont need uber- bike or take public transport!
