How to use mocopi application on PC

The mocopi PC application is now available.
The mocopi PC app makes motion recording and live-streaming in a PC environment easier than ever.


Since 6 sensors cannot be connected to a Windows PC at the same time, a separate smartphone and a dedicated mobile application (mocopi link) are required when using the mocopi application on PC.
There are two ways to send data from a smartphone to a PC: a wired connection using a USB cable or a wireless connection.

  1. STEP1: Preparation
  2. STEP2: PC-smartphone connection
  3. STEP3: Tracking mode selection・Putting sensors・Calibration
  4. STEP4: Motion tracking
