Touchscreens aren't the easiest to handle, especially when you are unfamiliar with the device, so the iDigiTip was invented to make navigation a lot easier.
The iDigiTip is a stylus specifically designed to help typing on screen with fingers a lot easier. The item is basically a ring with a pointed tip that makes clicking on icons much easier and accurate. The other benefit is that users will no longer have to deal with nasty smudge marks and fingerprints. The iDigiTip is one-fit only, but it's large enough that it should fit the other digits on a person's hand.
For those who aren't 100% comfortable dealing with touchscreens, but don't want to trade in their devices, the iDigiTip is the solution.
