What's the best Android app to use as a TV remote when the real one is lost?

Remote Control App For All TVs is a straightforward utility designed to replace a lost or broken television remote. Its primary function is to emulate infrared remote signals, allowing compatible Android phones with built-in IR blasters to control a wide range of TVs, set-top boxes, and air conditioners. The interface replicates a standard remote layout with essential buttons for power, volume, channel control, and numeric input, making it immediately familiar. For someone whose physical remote has vanished behind the couch, this app provides an instant, no-cost solution without requiring a Wi-Fi connection or complicated setup with the TV itself.

However, its utility is entirely dependent on hardware. The app cannot function on devices lacking an IR blaster, which excludes many modern phones. The developer, HOOHUA, supports the app through advertisements, which appear as full-screen ads between switching device profiles or occasionally when opening the app. Some users note in reviews that the ad frequency is understandable for a free tool. While it won't replace advanced smart TV apps that offer keyboards and touchpads, it serves its core purpose reliably. For basic channel surfing and power control on IR-compatible devices, it remains a practical stopgap while searching for the original hardware.
