A deep computer vision powered backyard predator detection turret that would auto target deer in the garden, raccoons by the chicken coop, etc and spray them with water (think super soaker). Would have auto mode or be able to move and target it with your app for fun.

I'd pay for a "Digital Life Concierge" app.

Something that audits all my subscriptions, passwords, cloud accounts, and digital footprints. And flags forgotten paid services, broken data sharing, or security risks. Lets me clean up or close accounts with one click.

An app like this could be the Marie Kondo of the internet age. If it existed, I’d pay for it today.

I'd pay for an app that was able to block time-wasters, play music and nag me. Apple's "Screen Time" is the 311-dad of this kind of thing, constantly approving extensions or letting you bypass outright, perhaps if the rules were more fine-grained (you can access off-limits sites only when you're out of the house on weekends) or if I could set up context sensitive nags like a full screen takeover to take a bike ride when it's sunny and nice out and not yet the hottest part of the day. It would also be nice to have context sensitive ambient music almost like you have in a video game where for example one could tune it to play light guitar music when you're just checking emails and fooling about, then some dnb during deep work. All the muddling about tldr I wish there was a kind of rule making system for self management
