## What is Simuii?

Simuii turns your iPhone into a responsive touch instrument for calm. Press, glide, or hold to shape a living field of color, spatial tones, paced breathing, and gentle haptics.

CHOOSE HOW YOU WANT TO ARRIVE
Select Calm, Sleep, Focus, or Release. Simuii adapts the session arc, energy, musical register, and breathing cadence to your intention.

AN INSTRUMENT, NOT ANOTHER FEED
There is no score to chase and nothing to scroll. Every touch sends a wave through the surface and releases a tone shaped by where and how you press. Each session is responsive and never exactly the same twice.

TUNED TO YOU
Optionally add your age, approximate location, or a short Sound DNA sample to personalize the musical tuning. Permissions are requested only when you choose a related feature.

YOUR PRIVATE JOURNEY
Optional before-and-after mood check-ins help you notice what genuinely settles you. Journey entries stay on your iPhone and can be exported only when you choose.
