You work with numbers all day long, your Macbook lacks the numeric keypad... Frustrated much? I'm sure that can be very inconvenient, that is until now.
Balmuda has just released their solution to your dilemma, Numberkey. [iTunes Link] The price to this solution is a small price to pay, coming in at $1.99. For that you get your ever so priceless numeric keypad. And for all of your who have OCD like myself, it will match your style of keyboard on your Mac. Whether it's white, black, or silver - Numberkey has you are covered.
To get set up you first need to download and install Balmuda's Mac software. Then head to the App Store and download Numberkey, turn on WiFi on both your Macbook and iPhone, and you are good to go.
It is also important to note, this is for Macs only, sorry Windows faithful!
