The app enables you to operate your TCL TV via your smartphone.
Please be aware that this remote control app is not the official TCL TV app, but it gives you the ability to control it.

The app has a wide variety of remote models, so you can find the one that suits your device.

The app was created so you could use your TCL TV device even if you couldn't find your remote. However, please note that the app requires your phone to have an infrared sensor.
