I want to make my smart phone smarter and I try AutomateIt because it is free. However, I don't know how to make it run a task when the task needs multiple conditions trigger. Thanks
Multiple triggers are supported on AutomateIt Pro: http://automateitapp.com/index.php/user-guide-2/composite-triggers-actions-pro-version-only/
As of version 3.0.54 (released on Feb 2013), you can unlock Pro features from within the free version.
