Type on your iphone using one hand

Install IOS 11 and you can benefit from Apple’s onehanded keyboard which allows for easier typing

It is near-impossible to type one-handed on an iphone Plus – the 5.5-inch screen stretches the keyboard a tad too far. With the same problem facing iphone X users, Apple has introduced a new feature: you can now shift the keyboard left and right. While it only works in portrait mode (and not on the ipad at all), it effectively creates an iphone Se-sized keyboard. You’ll still need to reach for functions at the top of the screen (we yearn for a URL bar at the bottom of Safari). But you can still doubletap the Home button to lower the screen and put the top half in reach (unless you have an iphone X where it’s been dropped).
