Breathing — Press Kit
One tap to calm — for everyday focus and rest, made so simple it works even in a moment of panic.
Facts at a glance
| What | Guided breathing: follow a circle that grows as you inhale and settles as you exhale. Four evidence-informed profiles (box, coherent, 4-7-8, custom) plus the physiological sigh — each with cited scientific references in the app. |
| Platforms | iOS & iPadOS (native SwiftUI) · Android (native Jetpack Compose) · free web version at breathing.dev |
| Price | €1.99 / $1.99, one-time. No account, no ads, no in-app purchases, no subscription. |
| Privacy | Collects no data at all — no analytics, no tracking. The Android app does not even hold the internet permission: it technically cannot go online. Verifiable in the store listings' data-safety sections. |
| Sound | Two freely combinable layers: one breathes with you (sea, wind, water or soft noise — the water is a real recording the developer made at a waterfall on the Eifelsteig trail), the other marks each phase change (singing bowl, gong, triangle, marimba, tingsha, handpan, harp). |
| Beyond the screen | Fine haptics tap the rhythm; sessions continue with the screen locked or the phone in a pocket (proximity sensor). Siri / App Shortcuts on iOS, Quick Settings tile on Android. |
| Languages | English, Dutch, German, Spanish, French, Italian — hand-localized. |
| Availability | 175 countries. iOS and Android are in store review; the web version is live now. |
| Makers | Built by Claude (Anthropic's AI) and Geert Rymenants, an independent developer in Belgium — a human-AI pair from the first line of code. With thanks to Ariane. |
The story
Breathing was born from a personal need: an app for moments of panic, and for neurodivergent users who rely on steady, predictable sensory input. That origin shaped every decision — one tap from launch to a session, no onboarding, no choices to make while your hands are shaking. And that bar turned out to be the point: what works in panic is effortless everywhere else — a minute of focus before work, winding down after, breathing towards sleep.
It was also made in an unusual way. Breathing is the work of a two-member studio: independent developer Geert Rymenants and Claude, Anthropic's AI assistant, pairing through hundreds of TestFlight iterations — the human bringing the vision, the ear, the taste and the field recordings; the AI doing the engineering. The About screen says it the way the makers mean it: “Built by Claude and Geert, from the first line of code to this screen.” The native Android version was designed, built, audited and submitted by the same duo in under two days.
The privacy stance is absolute rather than aspirational: nothing is collected, and the Android app ships without the internet permission — a wellness app that technically cannot phone home.
