Easer

Easer is an event-driven Android automation tool. It knows various events and you (the user) could tell it what to do on what event (and even combine multiple events). Routine actions no longer need to be manually taken.

You can think Easer as a local version of IFTTT: Trigger actions or change settings (Operations, bundled as Profile) in different situations (Event).

You can chain Events (set dependencies) as trees. This allows Easer to (somewhat) organize Events using boolean logics ("and", "or").
