About changes in system requirements for mobile apps and mobile browser

We regularly revise our recommended system requirements to ensure the best user experience and provide users with new features and updates even faster.

Using mobile apps or mobile browsers in an environment that does not meet new recommended system requirements does not immediately restrict all functions. However, some functions may be limited in the Teachme Biz version released on or after December 16, 2021. Any inquiries regarding usability or malfunctions can not be supported.

What should I do?

Please consider upgrading your device’s OS version ahead of time.

From February 2022, it will no longer be possible to install a mobile app on devices running iOS12 or Android 5.0~6.0.

We do not plan to restrict the launching and operating of apps already installed on devices that do not meet new recommended system requirements. However, please be advised that we cannot guarantee or provide support for operating in an unsupported environment.


We will continue working on improving our product quality and providing services that meet our customer’s needs.

If you have any questions or concerns, please feel free to contact us from here.
