Vianium apps are native and signed by us, not by the Microsoft Store (which no longer accepts new Windows Phone 8.1 apps). To install them, your phone just needs to trust our certificate once. One step, on the phone, no PC.
step 01
Download and install Vianium's signing certificate. You only do this once per phone.

With the certificate installed, you can open each app's .appx package and it installs directly: no Store, no unlocking the phone with weird tools. Packages are coming soon.
If the phone says the certificate is not trusted, open the .cer file again and choose install. The certificate is self-signed by Vianium; check that the SHA-1 thumbprint matches the one above before trusting it.
