One of the apps I use a lot on my Nokia Lumia 900 Windows Phone smartphone is Toggle, which adds easy shortcuts to settings directly on my homescreen with a live tile.
Toggle offers the option to add Live Tiles for a range of different settings shortcuts, including:
Each live tile will update in the background showing off the current state of that particular service and tapping on the live tile takes you directly to that option (i.e. clicking on the Wi-Fi live tile takes you to the Wi-Fi menu).
The only complaint I have with this app is the size of the tiles; as they don’t display a lot of information, the tile often looks too big and thankfully, this will change with the upcoming Windows Phone 7.8 update, which is built on the Windows Phone 8 platform.
Overall, Toggle for Windows Phone is a must have on my Nokia Lumia as it adds vital functionality with very little fuss and an easy to use user interface. The live tile updates accurately in the background and I’d definitely recommend Toggle for Windows Phone.
