## What is Useless APP?

Useless APP is a technology keynote you can actually play.

This release introduces the Off-Work Accelerator, where repeated taps push progress infinitely closer to 100%, and the Holiday Conservation Engine, where every simulated day off creates a later simulated workday. Neither feature changes system time or represents an official holiday schedule.

The museum also includes working local Pomodoro, todo, expense and notes mini apps; an AI subscription cost ledger; DAU One; App 38; the Ransom Alarm; and six classic useless exhibits. Completed interactions create locally stored collection certificates that can be turned into posters and shared through the user-initiated iOS share sheet.

All user counts, revenue, rankings, IQ, luck, awards, calendar dates and acceleration values are fictional exhibit content. The app does not measure or change a person, device, system time or real work schedule and promises no real-world outcome.

All exhibits are free. There are no in-app purchases, accounts, third-party ads, analytics or tracking. The app does not collect or upload personal data. The interface and exhibit content are in Simplified Chinese.
