The service is free if you just want basic scans after every workout. You only have to subscribe ($5 per month or $40 per year) if you want advanced data.

The technology will mainly appeal to dedicated gym rats, but mPort tells TechCrunch that the data could also be useful when shopping for well-fitted clothes, especially if you need something custom-tailored. It adds that the scans are particularly helpful for self-conscious newcomers -- you can get an analysis of your body in a private space, without the need for measurements from a trainer. The machines could get the ball rolling on regular gym exercise for people who'd otherwise be tempted to stay at home.
