Useless APP
Read full descriptionHide full description
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.

Verdict
The clearest difference is ads: Useless APP at none against ∞ Sudoku ∞'s shown. Useless APP also leads on update cadence (every 11 days vs every 12 months). ∞ Sudoku ∞'s advantage is iOS requirement (16.6 vs 18.0). On price, in-app purchases and device support there is nothing between them.
