Here are only some of the things you could do with Tasker.
Its real power is the flexibility to combine contexts and tasks
however you wish: https://tasker.joaoapps.com/exampleuses.html

☑ Automations
Make your phone a true smart phone! Why remember to change
the volume every day when you leave home when your phone can do it
for you?
Automate stuff based on the app you’re in the time of
day your location your Wi-Fi network Received
SMS or Calls the currently playing song and many other
(130+) states and events!

☑ Actions
350+ actions allow you to truly customize your phone like never
before! Send SMS create notifications change almost any system
setting like Wifi Tether Dark Mode Always On Display change any
volume control Do Not Disturb open apps file manipulation control
music playback get your location… you get the idea. If you can
think of it Tasker can probably do it for you!
Note: root is NOT (I repeat NOT) required for majority of the
functions. However a few of the actions (like the Kill App and
Mobile Data action on some devices) require root. This is because
of Android security policies that developers cannot work
around.

☑ Automatic File Backups
If you set it up to do so Tasker can automatically backup your
files to a specific folder on the device SD card USB key or even
Google Drive! This is useful if you want to keep your files safe
even if you lose your phone.

☑ Download and Install APKs directly
By your request (if you set up a task to do so) Tasker can
automatically check a website for updated APKs receive those APKs
from said websites and initiate installation of any files!

☑ Other Triggers
Manually trigger your actions via launcher shortcuts quick setting
tiles widgets long-pressing volume buttons media buttons (like the
ones on your BT headsets or headphones) Bixby button Navigation Bar
Notifications and more!

It’s not possible to fix problems reported via Play Store Comments
so please use the “Report Issue To Developer” option in the app
> Menu to do so.

Note 1: Tasker uses the BIND_DEVICE_ADMIN permission in
order to provide the System Lock functionality

Note 2: Tasker uses an accessibility service for some of its
features like closing the notification tray checking which app is
currently opened and more.
