Tasker is an Android app that allows users to automate various tasks on their devices. With over 130 states and events to choose from, users can create automations based on factors such as the app being used, time of day, location, Wi-Fi network, received SMS or calls, and more. This means that users can set their phone to automatically change settings or perform actions without having to manually do so. Tasker also offers over 350 actions, allowing users to customize their phone in ways they never thought possible. These actions include sending SMS, creating notifications, changing system settings, controlling music playback, and much more. While some actions may require root access, the majority of functions can be performed without it.

In addition to automations and actions, Tasker also offers features such as automatic file backups and the ability to download and install APKs directly. Users can set up Tasker to automatically back up their files to a specific folder on their device, SD card, USB key, or even Google Drive. Tasker can also check websites for updated APKs, receive those APKs, and initiate their installation. Other triggers for Tasker actions include launcher shortcuts, quick setting tiles, widgets, volume buttons, media buttons, Bixby button, navigation bar, and notifications. Tasker can even be used in conjunction with Join to trigger tasks from another Android device or PC.

Tasker is developer-friendly, allowing third-party developers to integrate their apps with Tasker and allowing users to call most Web APIs from Tasker using HTTP Auth and HTTP Request actions. The app also offers the ability to create custom user interfaces, standalone apps, and share or sell them using the Tasker App Factory. Tasker provides a 7-day trial period, after which users can make a one-time payment to unlock the full version. It is important to note that Tasker uses certain permissions, such as BIND_DEVICE_ADMIN and accessibility service, to provide its functionality. Users are encouraged to report any issues they encounter using the "Report Issue To Developer" option within the app.
