Ranked in these QuestionsQuestion Ranking
Pro Infinitely tweakable
Tasker has an impressive amount of triggers, actions, and parameters that can be used together in an incredible variety of ways. It can even accept scripts to follow instructions.
Pro Create powerful custom applications
Tasker has the ability to create custom applications, effectively replacing multiple installed apps in your phone with tasks that are triggered automatically. What's even better is that they will be custom tailored to fit your specific needs.
Pro Can adjust system software
With Root access it can also dabble with system software which other apps are not likely to achieve at the moment.
Pro Awesome plugin support
Tasker has awesome plugin support to connect with hardware that usually requires installing specific apps. For example, it has a plugin for Pebble smartwatch so that you can automate tasks that require using Pebble.
Pro Export tasks as standalone apps
Tasker allows exporting workflows you've created as standalone applications that can then be shared or even put on the Google Play store.
Pro Purchase only once
The dev does not keep bringing out revised apps expecting you to pay each and every time; the same app has been developed consistently for nearly a decade.
Con Awful user interface
While it's incredibly powerful, Tasker's user interface is counter-intuitive, confusing, and just plain clunky at every turn.
Con Steep learning curve
Tasker lacks good documentation or tutorials, which is important as the learning curve is very high if you want to use its advance features where this app actually shines.
