Now that the iPhone is also a phablet, there's probably no phone small enough you can use with just one hand. That means, your thumb isn't going to be able to reach the end of the screen now. The solution: the thumb extender.
Apple's latest models come in two sizes: 4.7" and 5.5" which means only one thing: too big for just one hand.
Enter the Thumb Extender.
Now you can reach anywhere on the screen. Rejoice now!
Made by Thanko, you can use it on the iPhone 6 Plus or Galaxy Note line.
