## What is motion2?

It's beautiful when the movements such as dance performance are synchronized. This app is an app that can quantify the degree of synchronization (matching) by comparing the acceleration data of two smartphones. Install the app on the smartphone that evaluates the movement, and try the matching movement for the teacher role (standard) and the student role (compared side). Acceleration data from two smartphones are compared and synchronicity is evaluated. In addition, detailed data such as translational acceleration, rotational acceleration, and posture can be confirmed as acceleration data, so it is possible to check the part where the movement is out of alignment and utilize it for the next performance. You can save comments for each performance and see your partner's comments. You can save up to 10 performance data for free. If you want to store more data, we also offer a subscription service.
