Authenticon

Authenticon is now free. Sync with a friend on a video call, read the matching code out loud, and keep the neon running. New: call mode, private notes, six languages.

A neon scene that never repeats, and a small ritual you do with another person.

Authenticon draws everything on screen from the clock. At the same moment, the scene looks the same on every phone in the world. That one fact makes the ritual work.

THE RITUAL On a video call, you both open Authenticon. Count down out loud: three, two, one. Then you both hold SYNC for two seconds. From that moment both phones run the same scene and show the same short code, like NEON · TIGER · 42. Read yours out loud. If the codes match, you really did sync together.

A video recorded yesterday cannot join a countdown that happens today. That is what the ritual is good for: it rules out replayed videos and lazy fakes, and it gives two people a shared moment of "we are both here right now".

To be clear about the limits: this is not a security product. It does not check who someone is, and anyone with the app who hears your countdown can sync too. Matching codes mean "we did this together", nothing more. We think that is still worth having, and we would rather say it plainly.

WHAT'S INSIDE • The sync ritual with spoken codes. • Call mode: one big shape and a giant code, built to survive webcams and video compression. Hold your phone up to the camera. • Private notes: a small notepad behind a PIN. Notes stay on your phone and are never uploaded anywhere. • A living vaporwave scene: a warped neon grid, a slowly turning triangle, scrolling poems, sparks that follow your finger. • Six languages: English, German, Spanish, French, Italian, Polish. Switch right inside the app. • Reduce Motion support for people who want the scene calm.

FREE AND OFFLINE The app is free. It works completely offline, sends nothing anywhere, and has no accounts, no ads and no tracking. There is one optional purchase: the Midnight theme, a darker blood-red look with its own set of poems. That is the only thing money buys here.

Try the ritual on your next call. It takes ten seconds, and it is a nice thing to stare at while you talk.
