I can't say I buy a ton of apps either. I do use a lot of apps though. Most for services or products I otherwise own or use. My sprinklers, my bank, brokerage, and credits cards, Zoom, iRobot, etc. I do also buy a few apps. Not a ton, but a few here and there. A few calculator apps, a few random games. Things like Pixelmator and Linea Sketch I use quite a bit.

I think I've bought more apps on my iPad than on my Mac. My phone not quite so many, but I've bought a few. Mostly not many because I don't use my phone as much as my iPad or my Mac.
