About

Bindu

Read full description

Bindu is a minimalist iOS app for guided coherent breathing exercises. Choose a pattern - Relax, Balance, Energize, or Reset - hold the start anchor, and follow the slow rise and fall of the orb on screen. A session runs about six minutes by default. The orb expands as you inhale and contracts as you exhale, with subtle haptic feedback that fades into the background. Listen mode When you want the calm without the structure, switch to Listen Mode for a generative ambient soundscape. Slow tones drift over a deep bowl pulse. Transport controls appear on the lock screen and in Control Center, so it keeps playing when the screen is off. Open-ended or with a timer (15, 30, 60 minutes). Yours alone No accounts. No logins. No analytics. No ads. Nothing leaves your device. Crafted between the ocean and the forest of les Landes, France.

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 โ€” Floozy, Nacho, and No-No! โ€” 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 โ€” Three real cats, three distinct purrs โ€” Per-cat haptic profiles drawn from each recording โ€” Sleep timer: 10, 20, 30 minutes, or โˆž โ€” Audio continues when the screen locks; haptics resume when you wake โ€” No subscription. No account. No analytics. No servers. Free. FOR Floozy, Nacho, and No-No!, and those who love them.
