森呼吸

For tired days and sleepless nights. Open the app, tap Start, and a forest surrounds you. Breathe for 3 minutes, then a soft bell ends it. No settings, no accounts.

Shinkokyu is an app for breathing deeply, as if you were standing in the middle of nature.

When you're worn out, stressed, or your focus is gone. On restless nights, too. Open the app and tap "Start" — a forest fills the screen, and the sound of a stream, birds, and wind quietly gathers around you.

When the circle swells, breathe in through your nose. When it shrinks, breathe out slowly through your mouth. In for 4 seconds, out for 8. Just repeat it for 3 minutes.

After 3 minutes, a soft bell rings and it quietly ends. It never cuts off mid-breath — it waits until you've breathed all the way out.

◯ Lose yourself in nature Photos of forests, waterfalls, and lakes from across Japan, with the sounds recorded there. The screen and sound alone open up the outdoors in front of you. The view drifts to a new place every 30 seconds, slowly zooming, layered with water, birdsong, and night insects. As your attention settles on the nature in front of you, the noise in your head loosens, and you slip into three minutes of simply breathing.

◯ Nothing to choose No courses, no background music to pick. Just open and tap. So you don't waste time deciding, the app chooses the scenery for you.

◯ Asks nothing of you No account, no notifications, no goals. If you can't keep it up, nothing blames you.

◯ No connection, no records We collect nothing about you, and never go online. The only thing kept is "how many times you opened it this week" — quietly visible in the home-screen widget.
