Doctor Who: EyeStalk ($2) is an iOS app that will exterminate photo boredom and transform your iPhone, iPad, or iPod Touch into the Doctor's oldest archenemy, an evil breed of cyborg known as Dalek. To celebrate the return of season seven, the official BBC-licensed app got an update that includes even more authentic Dalek effects.
EyeStalk comes with seven different Dalek filters based on the long-running British science-fiction series, including a blue monochromatic "Doomsday" lens and the most recently added "Asylum" gray monochromatic style. Take a photo from the app or choose from the Camera Roll and change Dalek effects by swiping left and right. Then share your "doctored" image to Facebook, Twitter, Flickr, Evernote, email, or SMS.
There's also video mode, which will transpose Dalek vision over your mini motion picture — just like the show! Give EyeStalk a download and don't worry about Daleks taking over your phone (it's the WiFi you have to worry about).
