Yesterday we shared with you a newly discounted app that turns your iPad into a professional drawing tablet for Mac and now we have another app deal that’ll help you get even more use out of your Apple tablet. Duet Display, the iOS app that allows you to use your iPad as an extra display for your Mac or PC, has just dropped down to $7.99. That’s 50% below its typical price and a match for the lowest we’ve seen. The companion Mac app is available for free. Full setup instructions can be found here.

Mount your iPad to the side of your MacBook, fire up Duet Display and you’ve got yourself a killer mobile workstation.

Duet Display allows you to use your iPad or iPhone as an extra display. Developed by a team of ex-Apple engineers, duet is the first high performance solution that has zero lag.

Work more effectively with duet. An additional display can increase productivity for engineers, musicians, designers, and artists by up to 48%.

To setup, download and open duet on your Mac or PC (for free) and on iOS. Connect your iDevice to your Mac using a lightning or 30 pin cable. Done.

No need to worry about firewall settings, Wi-Fi speed or your 802.11n network. Duet is secure, simple, and allows you to use your iOS and OS X devices in harmony.

And feel free to use your touch screen for interaction with your new display.
