## What is Rainbow Noise?

When the nap has to happen in the car, Rainbow Noise plays the right color of noise through CarPlay.

At home, seven colors cover the rest of the day. White for masking. Red and Pink for sleep. Green and Blue for focus. Violet for staying awake. Grey for long sessions.

One purchase. No subscription. The whole family shares it.


PLUS

White is free. The other six colors and the reverse alarm are in Plus.

The reverse alarm sets a stop time. The noise fades to silence at the moment you choose.

Plus is one purchase. No subscription. No ads. No data tracking. Buy it once, get every update.


THE SEVEN COLORS

White. Every frequency at equal weight. For masking traffic, neighbors, or the office hum.

Pink. Warm and steady. Good for falling asleep, napping, or sleeping all night.

Red. The lowest, heaviest end of the rainbow. The one people leave on through the night.

Green. The middle of the rainbow. Good for reading, writing, or thinking something through.

Blue. The bright, awake half of the rainbow. Good for careful reading, writing, and detail work.

Violet. The sharpest end of the rainbow. Good for road trips, big projects, or late-day energy.

Grey. Even across your whole hearing range. The kind you forget is on.


BUILT FOR iOS

Liquid Glass design throughout. Native CarPlay. Home Screen and Lock Screen widgets. Siri shortcuts for every color.


WHAT'S NOT HERE

No subscription. No auto-billing trial. No ads. No data brokers. No social features. No engagement streaks. No AI.

Just noise, in colors, and the right one for every moment.
