I know why everyone is making to-do lists and expense trackers
This is the screen for creating a new app in Android Studio:

They literally just click a button and viola, the app is ready! Then they make some LLM generate the typical "So I built my own..." post.
I'm not being critical. I'm just saying, well, if you ever wondered why 10 new to-do list apps are being posted here everyday, well, this is why.
