MMD ArLive is a character dance app that allows users to experience augmented reality while watching their favorite characters dance. The app uses the camera to track the character's movements and display them on the user's screen, creating the illusion that the character is right there with them. What's great about this app is that it doesn't require any specific markers, making it easy and accessible to use.

In addition to its AR features, MMD ArLive is also compatible with Mikumikudansu, a popular Windows free software for character animation. This means that users can freely customize their characters and dances according to their preferences. Overall, MMD ArLive is an entertaining app for those who love character dance and want to experience it in a unique and immersive way.
