In this research project an independent case study on the new contactless 3D body measuring native mobile applications has been carried out. The presented approach allows combination of three different measurement methods: the manual body measuring with the help of traditional instruments, 3D full body scanning technology and the contactless body measuring via smartphone applications. This paper discusses results of the investigation of usability of the measurement process via 3D body scanning apps on the Gage R&R methodology and the examination of their measuring accuracy. The current research provides analysis of body data obtained by the mobile scanning apps with the help of various methods.
