Store listing
By David Jacobson, from the App StoreDescription by David Jacobson Written by the developer, not by AppBrain. Click to read.
Around the canon are five larger surfaces:
• The Invitation: a 60-second cinematic opening that introduces the framework on first launch and can be replayed at any time.
• The Seven Shadows: a darker companion teaching for each principle — the loud mind, the false pattern, the restless body, the split self, the stuck current, the haunted cause, the transactional exchange — paired so the Seven becomes a fuller spine.
• The Symphony: a ten-minute journey through all seven principles in sequence, culminating in a lit heptagon finale.
• The Codex: a written book mode that extends each teaching with longer-form prose.
• The Measurements: science cards citing peer-reviewed work on the Schumann resonance, heart coherence, vagal tone, neuroplasticity, and the body's own biophotons. Educational, not clinical.
Tonos runs on iPhone and iPad, offline-first. There is no account, no network activity at runtime, and no tracking. The app is designed for daily tuning, a single minute between the noise, and it treats the user as intelligent rather than fragile.
