Using ONYAKU with mobile devices

Onyaku can also be used on smartphones. Please note that some features differ from the PC browser version and the Windows app.
On iPhone, you can use the iPhone app or a browser (Safari, Chrome). On Android, you can use a browser (Chrome).

Please download the iPhone app from the App Store. (For usage instructions, please refer to this article.)
For browser use on smartphones, the Login, Home, and Room screens are optimized for mobile devices. However, other features are not optimized for mobile screens, so we recommend using a PC for those features.
* As of June 20, 2025, we have stopped accepting new downloads of the Android app.
