I think I've only bought one or two apps my whole life. I don't remember them but I think it was to unlock my phone and to scan Chinese letters with my camera.

Most apps are free. There's really no reason to buy apps and I don't want my money going to corporations. Another annoying thing is everyone wants to charge subscription example, 10usd a month. That's too expensive for an app but most of all. Can't pay with lightning.
