Just upgraded from a iphone 4 to 5 and kaw is sooooo slow. Anyone else outthere with same problem??

If it's a android I recommend deleting apps you don't need and going into the Settings and into the Apps tab. Tap on any app such as Facebook or something of the sort and tap clear cache, do that for several apps to free up memory.

If new phone check version
swipe app needs version ios 7.0 or higher

- There are two ways to upgrade the iOS version of your iPhone, iPad, or iPod Touch - via connecting the device to iTunes on a computer
- or directly from within the device, but only since iOS 5, it is possible to upgrade the iOS version without the need to connect the iOS device to a computer (over-the-air update)
just go to: settings - general - software update
