Chris Gills Phone Apps

Chris Gill describes two phone apps he has created to help in the home workshop. The apps are designed to run on the phone operating systems (Android, Windows) or in a standard desktop browser. The apps are Geometry, which handles several calculations in plane geometry and MetalBender, which makes calculations for using a bending brake.

I may be being a bit thick here but I can't get these to install on my pc, I have tried the distributed files ie the .appx file and instal in Firefox and also rebuilt it on Phonegap. The result is always the same, thus:-

Geometry installation failed
Untrusted App

Access your Internet connection

Either a new certificate must be installed for this app package or you need a new app package with trusted certificates. Your system administrator or the app developer can help. A certificate chain was processed but terminated in a root certificate that isn't trusted (0x800B0109)

Any suggestions?
