Mint Wave: Sound Therapy

Mint Wave — moonlight ripples on your mind.

Mint Wave weaves emotion, sleep, and breath into one calm ritual. Whether you can't fall asleep at night or anxiety rushes in during the day, every layer of this app is designed to bring your body back to stillness.

REAL NATURE SOUNDS

The 25 soundscapes we curated aren't synthetic loops. Deep in the forest, at the shore, high in the mountains — each track is a real field recording by our sound designers.

Small waves brushing over rocks. Dawn birds and insects in the rainforest. The actual crackle of firewood. A howling snowstorm at polar latitudes. The gentle murmur beside a cafe counter —

Let real nature flow through your room. These true sounds lower your cortisol, restore heart rate variability (HRV), and gently trigger natural melatonin release.
