## What is Serena?

Breathwork for people that just want the protocol, not the ceremony. 

Choose a goal, start a session and follow clear visual cues with optional audio and haptic feedback. 

Serena pairs each breathing technique with research outcomes, protocol steps, and sources, so the session feels practical instead of mystical.

Breathing techniques included:
- Diaphragmatic Breathing
- Cyclic Hyperventilation
- 4-7-8 Breathing
- Coherent Breathing
- Box Breathing
- Physiological Sigh
