We're almost at the end of the list – it's time to reward those power users who are looking for a way to really get the most out of their devices. If you don't mind a fairly steep learning curve (and a $6.49 price tag), the Tasker app is the best way to make your smart phone smarter. The program uses "states" and "tasks" to automatically respond to all sorts of situations. So, for example, you could tell the phone to automatically mute its ringer when it's turned facedown. Or you could have it turn on GPS when certain applications (like Google Maps or Navigation) are active, then turn it back off when those apps close to save juice. Or you could have the phone's screen automatically dim to a preset level after 10 p.m., so you don't blind yourself if you have to take a call in the middle of the night. Or you could automatically bring up a list of music apps when you insert headphones into your phone or tablet. Or you could automatically mark your GPS location when you get out of your car, so you don't forget where you parked later. The possibilities are pretty much endless. Check out this video of a Lifehacker blogger using Tasker to create the ultimate alarm clock, complete with fading music and a personalized greeting.
