Some moments need a different kind of company. Binaural Purrs is an audio app built around four cat companions — each one designed for a different state of mind. Mio is for the slow, lo-fi moments when the day's been loud and you need quiet without explanation. Piper is for the working hours, when you need a desk cat who'll keep you company while the work gets done. Juniper is for the daydreaming hours, the ones that don't quite belong to the calendar. Mona is for rest. The deep kind. The kind that doesn't ask anything of you. Each cat comes with original audio scored to a specific brainwave state — alpha, beta, theta, and delta — designed using binaural beat principles to gently support the mood you're already in. This isn't a meditation app. It's not a productivity app. It's not a sleep tracker. It's something quieter — a small, character-driven space where the audio meets you where you are, and a cat sits with you while you're there. Press play. The right cat is already waiting. Features: — Four cat companions, each with original audio — Binaural beats engineered for calm, focus, meditation, and rest — Personalized character matching based on your current state — Designed for use with headphones for full binaural effect — Original artwork and sound design throughout Designed and developed by a two-person team who genuinely love cats and the way certain sounds change a room.
