Meet One-Handed Keyboard, the first (obviously) one-handed keyboard for the iPhone 6 Plus. It will help you type a little bit easier, but the only thing is, it won't make your big-arse phone any easier to balance in just one smallish hand.
The concept is simple: The One-Handed Keyboard is a replacement keyboard that's smaller than the phone's default keyboard so you can type more easily across a smaller surface area of letters with a single thumb. You can orient it to the right or the left, depending on which hand you use to type. Above, you can see me typing with One-Handed Keyboard on the iPhone 6 Plus. Below, I'm typing with the default iOS keyboard.
It's definitely helpful, but it's not a panacea for folks accustomed to using their phone with one hand but would otherwise appreciate the bigger size. It's not making your phone any smaller — I still had to try and hold a 5.5-inch device in one hand, which feels like some kind of balancing act.
This is a good start for keyboard alternatives for the big guy. But just a start; it's worth noting the app doesn't have predictive text in this build. But even with small keyboards out there, remember: The iPhone 6 Plus still is the big guy, and no tiny hand-friendly keyboard is going to make the actual hardware heft easier to handle.
