A breathing trainer inspired by the Wim Hof method, reborn as a living, adaptive rhythm engine.

BreathForge is an open-source project dedicated to the art of intentional breathing. It began as a meditation on the original wimhof concept — a breathing trainer built around the well-known Wim Hof breathing cycles — and evolved into something more: a personal respiratory rhythm coach that listens, adapts, and guides you through controlled hyperventilation, retention, and recovery phases without ever shouting at you like a drill sergeant.

If the original wimhof repo is a metronome, BreathForge is a conductor. It watches your cadence, adjusts the tempo, and composes a session that fits the shape of your day.

Breathing is the only autonomic process we can consciously hijack. That tiny loophole — the ability to override our own rhythm — is where BreathForge lives.

The project was born from a simple frustration: most breathing apps treat every human lung the same way. They play a chime, they count to four, they move on. But breathing is deeply personal. Your capacity shifts with sleep, stress, altitude, caffeine, and the weather outside your window. A trainer that ignores those variables is just a timer wearing a costume.

BreathForge was designed around a different premise: the rhythm should bend to the breather, not the other way around.

Instead of a rigid schedule, BreathForge uses an adaptive pacing model. It observes how long you comfortably hold, how quickly you recover, and how steady your inhale-exhale symmetry remains. Then it reshapes the next round accordingly. Over time, the app builds a quiet portrait of your respiratory signature.

This is not a medical device. It is not a cure. It is a companion — a gentle, thoughtful one — for people who want to explore the frontier between calm and control.

Three ideas anchor the project:

1. Rhythm is a language. Breathing patterns communicate something to your nervous system. BreathForge treats each session as a sentence rather than a checklist.
2. Adaptation beats prescription. A fixed 30-breath cycle works for some bodies and not others. BreathForge prefers to ask questions with pacing rather than dictate answers.
3. Silence is a feature. Most of the interface disappears mid-session. What remains is a fading gradient and a soft pulse — nothing that demands attention.

The result is a trainer that feels less like a workout video and more like sitting beside a calm instructor who knows when to speak and when to simply breathe with you.

BreathForge ships with a deliberately curated set of capabilities. Each one exists because a real testing session demanded it.

• Adaptive cycle pacing — inhale, hold, exhale, and recovery durations shift based on your own measured comfort envelope.
• Guided retention windows — retention timers that lengthen only when your recovery heart-rate estimate is stable.
• Round-by-round progression — structured multi-round sessions inspired by classic controlled hyperventilation protocols.
• Ambient audio cues — subtle tonal markers that guide without interrupting.
• Haptic rhythm support — vibration patterns for devices that whisper instead of chime.
• Session journal — a lightweight log of completed rounds, longest holds, and recovery trends.
• Custom program builder — define your own sequence of cycles and save it as a reusable routine.
• Dark and light visual modes — a night palette engineered for low-light rooms.
• Offline-first operation — the core session engine runs without a network connection.
• Cross-device continuity — continue a session on a different screen when you move rooms.

Every feature is optional. Every feature is quiet. Nothing nags.

A BreathForge session unfolds in four movements:

1. Calibration. The first thirty seconds measure your natural resting cadence. No prompts, no expectations — just observation.

2. Power breaths. A sequence of deep inhales and relaxed exhales, paced slightly faster than your measured baseline. The goal is controlled, not frantic.

3. Retention. After the final exhale, a hold begins. A soft indicator swells gently to show elapsed time. You are never told how long to hold — only offered the space to find out.

4. Recovery breath. A single deep inhale, held briefly, then released. The cycle repeats according to your chosen program.

Between rounds, a short reflection panel appears — a moment to note how you felt, if you wish. This reflection feeds the adaptation engine for the next session.

BreathForge renders fluidly from a wrist-sized wearable screen to a wide desktop monitor. The layout strategy favors a single breathing canvas that scales proportionally, with control surfaces collapsing into a floating tray on smaller viewports.

Key responsive behaviors:

• Adaptive typography that grows for glanceable reading during a hold.
• Gesture-first navigation on touch devices — swipe to skip, long-press to pause.
• Keyboard navigation with full tab-order support on desktop.
• Reduced-motion mode for users sensitive to pulsing animations.
• Landscape and portrait parity so rotating your device never breaks the rhythm.

The interface is designed to be interrupted. If you look away, nothing is lost.

Breathing is universal; language is not. BreathForge ships with a localization layer that supports right-to-left scripts, locale-aware number formatting, and duration phrasing that adapts to cultural conventions.

Currently available interface languages include English, Spanish, French, German, Portuguese, Italian, Dutch, Polish, Ukrainian, Japanese, Korean, Simplified Chinese, and Arabic — with community translations continuously expanding.

The localization system is intentionally permissive: adding a new language requires only a single translation file and no code changes. Voice cue scripts are stored separately from UI strings, so voice packs can be translated independently of the interface.

The companion guidance service runs around the clock. Whether it is 3 a.m. in one hemisphere or midday in another, the BreathForge assistant remains reachable for session questions, program suggestions, and gentle encouragement.

Support channels include:

• In-app contextual help that appears only when you ask for it.
• An asynchronous message queue for questions that do not need immediate answers.
• A curated knowledge base covering pacing, retention safety, and recovery.
• A human-supported response desk operating across all time zones, seven days a week.

No question about breathing is too small to ask.

BreathForge is built to be discovered by people searching for terms like breathing trainer app, guided breathwork companion, respiratory rhythm coach, controlled hyperventilation timer, retention training tool, and adaptive breathing exercises. Rather than scattering these phrases arbitrarily, they are woven naturally into documentation, help articles, and this README.

The goal is simple: when someone searches for an alternative breathing trainer, a guided breathwork companion, or an adaptive respiratory rhythm application, BreathForge should be findable — and, more importantly, worth finding.

Additional discoverable topics the project addresses include breath pacing for focus, recovery-breath timing, round-based breathing routines, mindful breathing journals, and privacy-respecting wellness tools.

Accessibility is not an add-on here; it is a design constraint from the first line of code.

• Screen-reader labels accompany every interactive element.
• Every audio cue has a visual equivalent, and every visual cue has an audio or haptic equivalent.
• Contrast ratios meet or exceed WCAG 2.2 AA thresholds in both themes.
• Session timers support pause, extend, and skip without penalty.
• Text scaling is respected up to 200% without layout breakage.

Breathing should be reachable by everyone, regardless of how they perceive the world.

BreathForge is composed of four loosely coupled layers:

1. The Rhythm Engine — a deterministic state machine that produces pacing instructions.
2. The Adaptation Module — a lightweight statistical layer that adjusts pacing based on session history.
3. The Presentation Layer — a rendering-agnostic view system that supports multiple front-ends.
4. The Persistence Layer — local-first storage with optional encrypted synchronization.

Communication between layers happens through a documented event bus, which makes it straightforward to swap out any single component without rewriting the others.

Everything that can be tuned, can be tuned. A sample configuration block (in YAML-like syntax) might look like this:

session: rounds: 4 base_pace_seconds: 2.0 adaptation_strength: medium retention_mode: gentle_growth audio: ambient_tone: soft_bell volume: 0.4 haptics: enabled: true intensity: low

Configuration files live beside the session journal, so a single backup preserves both your preferences and your history.

Your breathing data belongs to you. BreathForge stores session history on-device by default. Optional synchronization is end-to-end encrypted, and no telemetry leaves your machine unless you explicitly opt in.

There are no advertising identifiers. There are no third-party analytics scripts. There is no shadow profile quietly accumulating in a distant data center.

If you delete the app, the data goes with it — cleanly, completely, and without ceremony.

The 2026 roadmap focuses on deepening the adaptation engine and broadening device reach:

• Q1 2026 — Introduce mood-aware session suggestions based on journal reflections.
• Q2 2026 — Expand wearable integrations and refine haptic vocabulary.
• Q3 2026 — Release a plugin interface for community-built pacing programs.
• Q4 2026 — Publish a formal white paper describing the adaptation model.

Community priorities shift this schedule. If something matters to you, say so.

Contributions are welcome in many forms: code, translation, documentation, testing, and design critique. Before opening a large pull request, consider starting a discussion so the shape of the change can be agreed upon early.

Guidelines in brief:

• Keep pull requests focused; one idea per request.
• Include tests for behavioral changes.
• Prefer clarity over cleverness in code and comments.
• Be kind in review. Everyone here is learning to breathe.

The project maintains discussion spaces for questions, feature proposals, and shared session notes. Whether you are a first-time breather or a seasoned practitioner, there is a place for your perspective.

Guidance is available at any hour, and responses from maintainers typically arrive within a day. Community moderators help keep conversations grounded and welcoming.

Is BreathForge a replacement for medical advice? No. It is a wellness companion, not a clinical tool. Consult a qualified professional for medical concerns.

Does it require an account? No account is needed for core functionality. Synchronization is optional.

Can I use it without sound? Yes. Haptic and visual cues fully replace audio when sound is disabled.

Is my data shared with anyone? Only if you explicitly enable synchronization. Otherwise, everything stays local.

Can I create my own breathing programs? Yes — the custom program builder supports arbitrary cycle sequences.

Breathing exercises involving breath retention can be physically demanding. Practice in a safe environment, seated or lying down, and never in or near water. Discontinue immediately if you feel dizzy, lightheaded, or unwell. Consult a healthcare professional before beginning any new breathing regimen, particularly if you have cardiovascular, respiratory, or neurological conditions. BreathForge is provided as-is, without warranty, and is not a substitute for professional medical guidance. Sessions should always remain within a range that feels comfortable and controlled.
