It also is available as a widget for iPhone and iPad, and is available in multiple languages. Every 15 minutes watch faces that allow text display (Infograph for example) will show a random response. No need to open the app! Ask a question and glance at your watch face, and the complication will tell you the answer (as long as it has been over 15 minutes since you last tried). • "Schrode, should I download this app?". Schrode says, "Yes". Schrode the Cat is inspired by Schrödinger's Cat – a physics thought experiment devised by physicist Erwin Schrödinger in 1935. You can choose to turn off "zombie mode" to adhere to strict "Schrödinger mode” too if you are a physics nerd, or scared of zombies. • "Would Erwin Schrödinger have approved of Schrode the Cat?". Schrode says, "Certainly”. So what are you waiting for? Download Schrode the Cat now.

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.

Verdict
The clearest difference is update cadence: Useless APP at every 11 days against Schrode the Cat's every 9 months. Schrode the Cat's advantage is device support (5 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.
