I was writing a comment about the durability of this app, but you beat me to it. Something tells me that the burden of maintaining this thing through various OS updates, security policy changes (from Apple and Google), new devices, etc. is going to be frustrating for him. It's great that he vibecoded something useful to him in this moment, but I do think these stories are "counting their chickens before they hatch" so to speak.

It's not like you can't write "update this for next round of forced obsolescence " to Claude. Yes, it's unnecessary burden but solvable.
