If you tend to type a lot on your iPhone 6, and not just texting your buddies for dinner plans, then you could probably use an external keyboard to help speed things up.
Fosmon makes a portable mini keyboard that is about as small as an iPhone 6 and comes with a trackpad and arrow keys. While the track pad is only useful for non-iOS products, the arrow keys provide a movable cursor while you type.
They keyboard is made from lightweight plastic materials and features backlit keys for typing in the dark. On the right side of the keyboard, there sits a trackpad and four directional arrow keys. The iOS operating system isn’t compatible with trackpads. However, the arrow keys make it possible for you to move your cursor around on text easily. So, if you notice a mistake in the sentence above, you can just arrow-up and fix it.
The device is designed for universal use and even has a software setup where you can choose which operating system you are using. This assigns specific functions to certain keys based on whether you are using iOS, Android, or Windows. Function keys provide actions for your iPhone, like the Home button, volume controls, and more.
Fosmon’s mini Bluetooth keyboard is available on Amazon for $22.
