Horagai: Japanese Conch

Blow well, make a good sound.

Horagai turns your iPhone into a playful take on the Japanese conch horn.

Point the mouthpiece toward your iPhone's microphone, keep a little distance, and send a steady, moderate breath. Breath strength changes the volume. Tilt or quickly shake your iPhone to move between lower and higher pitches.

It will not always respond in exactly the same way. The satisfying moments when it sounds—and the funny moments when it does not—are both part of the experience.

What you can do • Change the volume with your breath • Tilt or shake your iPhone to change the pitch • Drag, resize, and rotate the horagai on screen • Gently tap your iPhone while you are not playing to hear a muted, hand-drum-like sound • Reopen the help screen at any time to review playing tips and safety notes

Ads The free version shows ads in Settings and while caring for your horagai. A one-time Remove Ads purchase hides all ads. Previous purchases can be restored. The App Store displays the actual price for your region.

Privacy Horagai uses the microphone to detect breath strength, but it does not record, save, or transmit raw audio. Version 1 has no recording, account, or cloud-storage features.

Play safely Keep a little distance from your iPhone and do not blow excessively hard into it. Take care to keep moisture from your breath out of the microphone and charging port. Please be considerate of the people around you, the place, and the time when playing loudly.
