What's the best Android app to use as a backup remote for a Roku TV?

TV Remote Control for RokuTV is a practical and functional solution for users who need a dependable backup control for their Roku-powered television. The app's primary strength is its straightforward setup; it typically connects to a Roku device on the same Wi-Fi network within seconds, requiring no complex pairing process. This makes it ideal for real-world scenarios like a lost physical remote under the couch cushions or a sudden battery failure right before a movie starts. The interface replicates a standard Roku remote layout with directional pad, playback controls, home and back buttons, and even includes a dedicated keyboard for text entry, which is often faster than navigating an on-screen keyboard with a physical remote. Reviews indicate users appreciate the app's reliability, with many specifically mentioning they purchased the lifetime ad-free version as a permanent insurance policy against a lost remote. However, the free version is supported by banner ads, which can be obtrusive. Some users on forums outside the Play Store have noted occasional connectivity hiccups if the phone's Wi-Fi is unstable, but overall, it provides a comprehensive and convenient remote experience directly from an Android device.
