Rubi: Red Light Therapy

Rubi turns your iPhone or iPad into a calm, deep-red light for the end of your day. One tap starts a 20-minute wind-down ritual: the screen fills with gentle red light, an optional breath pacer keeps you company, and when the timer ends the light fades slowly to black — it will never flash white in a dark room.

WHY RED? Bright, blue-heavy screens in the evening tell your brain it is still daytime. Red sits at the low-energy end of the spectrum and has the smallest alerting effect of any screen color. Rubi swaps the late-night feed for twenty quiet minutes of soft red light.

ONE TAP, THEN NOTHING • Start your ritual with a single tap — no buried accessibility settings, no triple-click hacks • Session timers from ten minutes to open-ended, always ending in a slow fade to black • Rubi raises your screen brightness for the session and always restores it afterwards • The screen stays awake for the whole session, no tapping to keep it alive

MADE FOR REAL NIGHTS • Baby Light: a touch-locked red light for night feeds and checks — the screen ignores every touch until you hold for three seconds, so it can never flash white in the nursery • Five light colors from deep red to warm white, plus a custom color picker • Six gentle sounds — rain, brown noise, ocean, thunderstorm, crickets, soft fan — that mix politely with your music and podcasts instead of muting them • An optional breath pacer (four seconds in, six seconds out) for winding down

BUILD THE HABIT • A quiet log of your evenings: streaks, sessions, and calm minutes • One gentle daily reminder if you want it — the only notification Rubi will ever send • Own a real red light panel? Rubi works just as well as the session timer and consistency tracker beside it

THE HONEST SCIENCE A phone screen cannot replace a red light therapy panel, and Rubi will never pretend it can — no skin, collagen, or pain-relief claims, ever. What your screen can honestly give you: gentler light, a bounded ritual, and a reason to put the feed down. The full, sober explanation lives one tap away inside the app.

A FAIR PRICE AND A QUIET APP • The core ritual is free forever: the 20-minute timer, deep red light, touch lock, and two sounds • Rubi Pro is one price, once — no subscription, no ads • No accounts, no tracking, nothing ever leaves your phone

Wind down tonight.
