Tests & Toys
Typing, reaction and click tests; mic, webcam, keyboard and screen checks; timers, metronomes, spinners and honest randomness.
Half diagnostics, half delight: the device tests tell you the truth about your microphone, camera, keyboard and screen before the meeting or the return window; the self-tests measure typing, reaction and clicking with honest bands; and the toys — wheels, timers, tempo tools, the 8-ball — bring ceremony to small decisions. Everything runs on your device.

How URSY.io approaches tests & toys
Device tests use browser APIs locally and never record or transmit — several state on the page that no capture code exists. Randomness is cryptographic and says so. Timing tools state their precision honestly, including where browser throttling or screen latency bounds what a webpage can measure.
