The app can be used to control Fujitsu air conditioners.

Despite the fact that this isn't the official Fujitsu air conditioner app, you can still control it using this remote control app.

Based on what device you have, you can choose from a variety of remote models using the app.

For Fujitsu air conditioners, we developed a remote control app that lets you operate the unit without a remote control!
This app does require an IR sensor on the phone, though.
