Just occasionally someone points out an application to you, and you go wow, that’s really useful; Tasker seems to be one of those such applications. Designed along similar lines to Locale (which has so many plugins from different people now, and all charge for them, it’s difficult to see the good and bads ones anymore), it offers the ability to create rules and control a whole raft of different functions on your Android phone. It’s not free (it costs £3.99), but this seems well worth given the range of controls it has.
I particularly like the ability to make system changes when you run particular apps, so, for example, you can keep the GPS generally turned off (to preserve battery life), but then when you run Google Maps you can turn on the GPS, and turn it off again when you exit. In fact, the range of triggers is fascinating; Application, Time, Day, Location, State or Event.
LifeHacker here has a tutorial on how to set up the auto GPS function, how to create an alarm in the morning (that also fires up your favourite apps), and to create a “Face Down” task which shuts off GPS, WiFi and Bluetooth, and makes the ringer quieter.
For even more options, this LifeHacker post goes further and discusses the following options: reading out SMS messages (for when you are driving), limited data usage overnight, pop up a menu of music apps when headphones plugged in, mark and find your parking place, and most importantly, it links to the Tasker Wiki, where a whole range of users have added information on their suggested profiles.
There’s also lots of information about the application, including a tour of some of the features on the Tasker website here, which is well worth a look too.
This is one very comprehensive application, which looks like it has the power to really customise the way you use your Android phone.
