MUUM: Body Echo
Your State in Color
Free · In-App Purchases · Designed for iPhone
Your body detects stress before your mind does.
MUUM makes it visible in real time through a living, color-shifting sphere that reflects your physiological state - then adapts your breathwork instantly based on what your body actually needs.
Not generic meditation.
Data-driven self-regulation.
MUUM selects and adapts breathing patterns based on:
* Stress level
* Energy level
* Recovery state
You don’t guess what to do.
Your body decides.
Train your regulation system
Stress
Downshift in seconds when your system is overloaded.
Energy
Recharge when you feel drained or unfocused.
Recovery
Return to baseline after mental or physical strain.
Research links structured breathing with:
* Improved heart rate variability (HRV)
* Lower resting heart rate
* Better stress resilience
* Improved sleep quality
Privacy
Your body data stays yours. MUUM only accesses health data with your permission and never sells personal data.
Important note
MUUM is not a medical device and does not provide medical diagnosis or treatment.
It is designed for self-regulation and awareness, not for crisis situations.
If you are in distress or crisis, please seek professional help.
