PeriZen: Invisible Focus Ring

PeriZen is a quiet focus timer with subtle ambient light and gentle posture prompts.

Choose your own pace
Swipe to set a focus duration, start a solo session, and review your session history on this device.

Gentle posture prompts
When you choose to use posture tracking, the front camera and device motion help estimate changes from your calibrated position. Camera frames are processed on device and are not recorded or uploaded. Tracking quality depends on positioning, lighting and visibility.

Companion rooms
Join a public room or share a six-digit private room code. The online service relays an anonymous connection identifier, a companion label, current focus state and elapsed focus time. Room codes are shared access codes, so give a private code only to your intended companions. Internet is required for online rooms; camera images are not sent to the room service.

Respect your display
PeriZen temporarily changes screen brightness and auto-lock during an active session, then restores the previous settings when you leave or the app moves to the background.
