About

Purr Machine

Features
Read full description

Purr Machine simulates the physical comfort of a cat purring on your chest. Lie down. Put the phone on your chest. Close your eyes. Three real cats — Floozy, Nacho, and No-No! — and their actual recordings. Every breath, every bell jingle. THE HAPTIC IS THE POINT Each cat's haptic pulses at the breath cycle measured from their own recording. A continuous purr modulated by breath, with a subtle heartbeat underneath. Two patterns running simultaneously on the iPhone's Taptic engine. Nacho's rhythm is Nacho's. Floozy's is Floozy's. WHAT'S IN IT — Three real cats, three distinct purrs — Per-cat haptic profiles drawn from each recording — Sleep timer: 10, 20, 30 minutes, or āˆž — Audio continues when the screen locks; haptics resume when you wake — No subscription. No account. No analytics. No servers. Free. FOR Floozy, Nacho, and No-No!, and those who love them.
