Elixir is the app you need anytime you're looking for information about your device. Both on the hardware and software side, Elixir tells you everything (and I mean everything) you'll ever want to know about things like your battery status, signal strength, build configuration and sensors. If having all this information at the ready when you open the app isn't enough, there are 16 different size and configuration widgets, which are completely customizable with access to all the app information as well as a full set of toggles for radios, sync, orientation, and screen lock. Anyone who wants to hack away at their device should give Elixir a try, and it's invaluable when you're evaluating a new device. It's free on the Android Market for devices running Android 1.6 and higher.
