Hand a task to someone in the house. Pesterpop reminds them, then reminds them harder, timed to a deadline only you can see. You get to stay the nice one.
It is exhausting, it makes you the bad guy, and it never actually gets the shelf up. Pesterpop takes the job.
Nudges land on their phone halfway to the deadline, at 80%, on the day itself and every day after. Quiet hours from 22:00 to 08:00, and no nudge is ever sent twice. Tap the ladder to hear the tone change.
Every task carries points. Finish it, send a photo, get approved. The scoreboard settles arguments that used to take a whole evening.
One photo settles it. The person who assigned the task gets 48 hours to be reasonable, then it auto-approves.
Free to use. Six digits, no email, no password. Your household is set up before the kettle boils.
