Gizmoot Player allows Android TV or Fire TV devices to be controlled from a smart phone or tablet.
The smart phone or tablet must be connected to the same WiFi network as the TV.
Install and run the Gizmoot App on the smart phone or tablet, which will find the TV running the Gizmoot Player App. Use the Gizmoot App to browse movies, photos, podcasts and internet radio to play on the TV.
Gizmoot Player is available as a free app on the Google Play and Amazon online stores.
