Madbits have just released its new iPhone photo app, Momentsia. The app’s simple-to-use features are “designed to let creativity flow naturally, allowing iPhoneographers to artfully express their experience through beautiful collage compilations,” the company says. Users simply select one of Momentsia’s colorful “Mondrian”-style collage layouts and snap photos into position by either tapping directly on the screen to capture the current moment or browsing their iPhone Camera Roll library to pair moments from yesterday with those of today. The free app is available now from the iTunes App Store.
