Breathing — Press Kit
One tap to breathe — for everyday focus and rest, with a simple, predictable interface.
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. |
| Haptics | The distinguishing feature of the native apps: a firm haptic tap at every change of phase and lighter taps on the seconds in between, so the rhythm can be followed with the eyes closed. With sound on, a session continues while the screen is locked; on iPhone the vibration then switches to simple system pulses and returns to its fine-grained patterns after unlocking. Browsers allow little or no vibration, so the free web version cannot reproduce this — a technical limit, not a product decision. |
| Platforms | iOS & iPadOS (native SwiftUI) · Android (native Jetpack Compose) · free web version at breathing.dev |
| Price | One-time price: €1.99 / $1.99. No account, no ads, no in-app purchases, no subscription. |
| Privacy | The native apps collect no usage data — no analytics, no tracking. The Android app does not even hold the internet permission: it technically cannot go online. Messages sent voluntarily to feedback@breathing.dev are handled as described in the privacy policy. |
| 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 | On supported devices, optional gentle haptics tap the rhythm while the phone is unlocked. With sound enabled, audio continues when the screen locks; if haptics are also enabled on iPhone, the rhythm switches to short system taps while locked and returns to its fine-grained patterns after unlocking. On supported phones, slip the phone unlocked into a pocket and the proximity sensor darkens the screen while the session continues. Siri / App Shortcuts on iOS, Quick Settings tile on Android. |
| Languages | Localized in eight languages: English, Dutch, German, Spanish, French, Italian, Japanese and Korean. |
| Availability | Available on the App Store for iOS and iPadOS, on Google Play for Android, and as a free web version at breathing.dev/app/ — no account, no installation. |
| Makers | Developed by Geert Rymenants, an independent developer in Belgium, in collaboration with Claude, Anthropic’s AI assistant. With thanks to Ariane. |
The story
Breathing was born from a personal need for an app with steady, predictable sensory input, including when feeling overwhelmed. That origin shaped every decision — one tap from launch to a session, no onboarding, and few choices at the point of use. The same low-friction design also suits a minute of focus before work, winding down after, or breathing towards sleep.
Breathing was developed by independent developer Geert Rymenants in collaboration with Claude, Anthropic’s AI assistant. Geert provided the product direction, design decisions, testing, sound choices and the waterfall recording; Claude supported the engineering and documentation. The About screen credits both: “Built by Claude and Geert, from the first line of code to this screen.” The native Android version came from the same collaboration.
The privacy stance is concrete rather than aspirational: the native apps collect no usage data, and the Android app ships without the internet permission — a wellness app that technically cannot phone home. Email feedback is the one voluntary data flow and is documented separately in the privacy policy.
