Sazameki turns the music in the room into light on your screen. Each phone listens through
its own microphone and responds to the beat on the device, so phones in the same room respond to
the same music without sharing any audio.

Getting started
- Read the flashing-lights notice, then allow the microphone when asked.
- Play music through a nearby speaker, or another phone. The picture moves with the beat.
- Tap the screen to show the controls for a few seconds: scenes, colours, and Internal / Mic. Double-tap to enter full-screen mode.
- In a quiet room, choose Internal: the app plays its own tones and the picture follows them.
At a live event
Scan the QR code at the venue to join its room. The host chooses the scene and the colours,
and every phone in the room follows. In a live room, you can see the scene the host selects,
even if you haven't purchased it; some scenes appear only when a host plays them.
Scenes and purchases
Ori, Hamon and Kushi are free. Nagare is a one-time purchase that lets you select it
yourself.
To restore a purchase on a new or reset device, open Settings (the gear at the top left) and
tap Restore Purchases, or tap Nagare and choose Restore Purchases. Use the same
Apple Account you bought with. To request a refund, visit
reportaproblem.apple.com; Apple reviews refund requests.
If the picture does not move
- Play the music through a speaker. Sound in your earphones does not reach the microphone.
- If you refused the microphone, turn it on in the iOS Settings app (Sazameki → Microphone), or choose Internal.
- A room link opened in a browser shows the web version. Install Sazameki and open the link again to use the app.
Flashing light
Sazameki shows light that flashes with the music, at times close to full white. If you are
sensitive to flashing light, take care, and stop at once if you feel unwell.
Requirements
iPhone or iPad with iOS 17 or later. Portrait or landscape on iPhone; any orientation on
iPad.

会場の音楽を、それぞれのスマホが自分のマイクで聴いて光ります。最初に光の点滅の注意を読み、マイクを許可して、
音楽をスピーカーから流してください（イヤホンの音はマイクに届きません）。静かな場所では Internal を選ぶと、
アプリ内で音が再生されます。会場では QR コードを読み込むと、その場の部屋に入ります。
Ori・Hamon・Kushi は無料、Nagare は買い切りで、買うと自分で選べるようになります（会場の部屋では、ホストが流せば買っていなくても見られます）。機種変更した場合などは、設定（左上の歯車）の
「Restore Purchases」で購入を復元できます（購入したときと同じ Apple Account で）。返金を希望する場合は Apple の「問題を報告」から申請できます。返金の可否は Apple が判断します。
光の点滅に敏感な方はご注意ください。気分が悪くなったらすぐに使用をやめてください。
iOS 17 以降の iPhone・iPad に対応しています。iPhone は縦でも横でも、iPad はどの向きでも使えます。
