Universal TV Remote is an iPhone/iPad app developed by Nilu Technologies that allows you to control your Smart TV from your mobile device. The app mimics the functions of a real TV remote and eliminates the need for external hardware. To use the remote, your iPhone/iPad must be connected to the same wifi network as your Smart TV and you must accept the message that appears on your TV screen.

The app comes with a range of features including power on/off, mute/unmute, volume up/down, channel up/down, menu button with up/down and left/right, video control (play/pause/stop), touch bar for easy navigation, and the ability to cast photos and videos. The app is free to download, but there are auto-renewing subscription options available for unlimited use.

If you choose to subscribe to any of the available options, you can enjoy all the features of the app. Payment will be charged to your iTunes account upon confirmation of purchase. The subscription automatically renews unless you turn off auto-renewal at least 24-hours before the end of the current period. You can manage your subscriptions and turn off auto-renewal by going to your account settings after purchase.

Overall, Universal TV Remote is a useful and convenient app for anyone looking to control their Smart TV from their mobile device.
