This app uses AR technology to make your fave hololiver appear right in front of you~ You can even make them do the preset poses in the app.
As of now, the characters are: Sora, Roboco, Mel, Aki, Haato, Matsuri, Aqua, Shion, Choco, AZKi, Miko, Okayu, Marine, Kanata, Watame, Lamy, Nene, Botan, Polka, and Ankimo.
I will try to update this review whenever they add or remove someone.
Really cool app to be honest. Of course, you'd need to have a phone capable of supporting AR for the full experience, but even without, you can use the app with the default background.
