About Purr & Relax

Purr & Relax is a calm, companion-style app designed to help you unwind, settle your thoughts, and ease into rest.

The experience is built around a simple idea: the quiet comfort of a cat purring nearby. Each session begins with a single tap and a gentle, living sound — created in real time on your device so it never feels mechanical or repetitive. Like a real animal settling in, the rhythm changes just enough to feel present and alive.

There’s nothing to set up and nothing to manage. You start a purr, choose how long it should last, and let it fade away naturally as you rest.

A gentle nightly ritual

Living purrs, created on-device. Every purr is generated locally and evolves over time, creating a natural, organic texture rather than a repeating loop.

Fade-out controls — ‘About 28 minutes Remaining’ with ‘Long Press to Add Five Minutes’ hint, plus a fluffy cat illustration and a Purr button set to 30 minutes, under ‘set a fade-out that knows when to end’

A soft fade-out for rest and sleep. Sessions end gradually instead of stopping abruptly. If you need a little more comfort, a single tap extends the purr without breaking the calm.

Distinct purrsonalities. Each cat has its own temperament, pacing, and sound character — subtle differences that change how the purr feels and settles into the room.

Quiet visuals that stay out of the way. Slow, minimal motion supports relaxation without drawing attention or demanding interaction.

Designed for background and lock-screen listening. Let the purr continue while your phone rests on the nightstand, in your pocket, or with the screen locked.

Free and optional premium access

One purrsonality is fully available for free, so the app is immediately useful the first time you open it. Additional purrsonalities can be explored through short previews, with full access available via an optional subscription.

The experience remains calm and complete either way — premium access simply adds more ways to find what feels right for you.
