AutomateIt for Android Does What it Says
"Using triggers and actions, you can save your battery from itself, make setting up your phone in your car far more convenient, and otherwise nit-pick things you wish your phone could do."
If Tasker is a bit too fussy (and expensive) for you, maybe AutomateIt will work better for you. All you need to do is set up a trigger which will launch an action and your in business. Easy automation of tasks like notifying you of events like loss of Wi-Fi signal, SMS-based triggers, battery-level triggers, and so on. It looks easy and useful and is free in the Market and works wherever you find our favorite little green guy.
I use Toggle Settings which has both a free and paid version, but I'd like to hear what you like to use? One of the above or something I haven't mentioned? Let us know at the "Discuss" link.
