Seriously? I have a custom Android app that I use. It's mostly vibe coded now, which I'm a bit embarrassed about, but demonstrates that the bar for custom software is very low at the moment and getting lower.

I considered getting an iPhone to replace my S-series Samsung, the only reason I stayed with Samsung is for the S-Pen. Had I gone with iPhone I would not be able to write and run my own software? That's absolutely ridiculous.
