The purrfect decision maker! Ask Schrode your yes/no question, tap the box, and Schrode will answer. Is Schrode alive, dead, or perhaps the undead?! Use Schrode the Cat to make decisions in your life: • "Should I eat pizza for dinner tonight?” • "Is bubble tea the best drink ever made?” • "Should I go to the movies tomorrow?” You can even use Schrode to answer your friend's questions in Messages. Just reply with Schrode for Messages. Let Schrode make the decision for you! Schrode the Cat works on Mac, iPhone, iPad, Apple Watch, Apple TV and even Messages on your iPhone and iPad. 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. And don’t forget to download it for Apple TV and Mac too, so you can ask Schrode questions from the comfort of your living room! *Please note that the answers Schrode supplies are for entertainment purposes only.

Copy some short text to your clipboard, and in messages hold 1 finger on the closed box in the messages app and wait a few seconds!

About

Useless APP

Features
Read 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.
