Aeolian: Breath Field Manual

Aeolian is a field manual of the breath: a calm, offline guide to breathing techniques and the real evidence behind them. Breathing is a dial you can turn. Fast, sharp breaths tilt you toward alert; slow breathing and long exhales tilt you toward calm. Aeolian helps you steer, with a real-time pacer that shows you exactly when to breathe in, hold, and breathe out. FREE TO START Three techniques are yours free, with the full guided pacer: Physiological Sigh, Box Breathing, and Diaphragmatic Breathing. No account, no sign-in, no trial clock. ONE UNLOCK, THAT'S IT A single purchase of $9.99 opens the rest of the manual: every technique with the guided pacer, the full evidence library, and extra theme presets. It is a one-time purchase, not a subscription. Buy it once and it is yours to keep. WHAT'S INSIDE - A real-time breathing pacer with gentle haptic cues at each phase - Techniques for winding down, finding balance, and gently energizing - Plain-language explainers grounded in published research, with honest strength ratings - Guided multi-day journeys and quick routines - Ten themes, from parchment daylight to deep midnight - 42 languages PRIVATE BY DESIGN Aeolian works fully offline.

WORKS WITH APPLE HEALTH Optionally log your completed sessions to Apple Health as Mindful Minutes, or read your recent heart rate and HRV to see how a session landed. All of it stays on your device. SAFETY FIRST Aeolian is a wellness and education tool, not medical software, and it does not diagnose or treat anything. It leads with clear safety guidance and per-technique cautions, and those are always free and never locked. The techniques here are for exploring how breathing can shift how you feel; they are not a treatment for any condition. If you have a health concern, talk with a qualified clinician. Breathe, remember.
