This article explains how to install & use TDUK App Killer on FireStick. The instructions in this guide apply to all Amazon Fire TV devices, such as FireStick, FireTV, FireStick Lite, FireStick 4K, and 4K Max.
What’s TDUK App Killer?
TDUK App Killer is an official app designed to help you kill the apps running in the background. This includes programs you don’t shut down to access again quickly and applications automatically launched by the device.
These apps hog internal storage, cause excessive cache, and can eventually affect the processing speed of your device. This application is available for $1.99 on the Google Play and Amazon App Store. It allows you to shut down unnecessary background apps with just one click.
The app is similar to Fast Task Killer. However, TDUK is on Amazon Store and paid, while Fast Task Killer is a third-party app and free.
