The largely popular Appearance Miku augmented reality app, Mikuture, has recently been updated to version 2 for iOS devices. The update brings all the same features added to the recent Android version update, which includes a new UI, and 5 new models: Snow Miku, Sakura Miku, Tda Miku, Yuzuki Yukari, and vFlower.
Additionally, both versions received an update to add a second Yuzuki Yukari model featuring her VOCALOID4 outfit. Simply update your apps to gain access to the new model. The developer, Sorasu, seems to always be working on interesting ideas for the app, and you can find various image tweets on the Mikuture twitter.
