Here’s something ultra-useful for all those Mac laptop owners who need numeric keypad from time to time. It’s an iPhone app called NumberKey, which will display a numeric keypad and wirelessly connect (via Bonjour) to your Mac to allow input of numbers much faster.

As you can see from the image above, the app is designed to follow the look of Mac’s keyboard, meaning when you put your iPhone near your laptop it will look like they were made one for the other. Four skins are available - black, white, silver and classic.

NumberKey works with both PowerPC and Intel CPU-based Macs and you can grab it for $1.99 from the AppStore.
