Smartphone and smart computer

You can use smart computer in mirror mode or sensor direct mode depending on your preferences or the situation.

  • What is Mirror Mode?

    Mirror Mode refers to syncing smart computer with Cateye's smartphone app, Cateye Cyling™. By using smart computer with Cateye Cycling™, you can connect smart computer and optional/third party sensors (speed, cadence, heart rate, and power) with the Cateye Cycling™ app, and record log information including your smartphone's GPS function while you measure. In this case smart computer becomes a monitor that displays smartphone measurement data in real time.

    By mounting a smart computer on your handlebars, in addition to being able to operate the Cateye Cycling™ smartphone app when your smartphone is in your bag or pocket, you can also view measurement data and check if you have received any phone calls or emails.

    This feature reduces smartphone battery consumption and reduce the risk of dropping your smartphone.
