This seems cool. How does it work?

It's simple, really. PurpleStore uses the iOS app deployment (usually used in business environments) web protocol itms-services:// to download apps via .plist files.
On Windows 10 Mobile, PurpleStore uses the App Installer web protocol ms-appinstaller:// with .appx/.appxbundle files.

You pretty much just need an iDevice (iOS 6.0.1 to iOS 12, iOS 4 does not work and iOS 5 is untested.) or a Windows 10 Mobile compatible Windows Phone.

Requirements!

iDevices

You'll need to jailbreak. If not, this won't work. You can find a guide here.
Once you have Cydia, go search for AppSync Unified.
If you can't find it, just do some Googling.
After you have that installed, it's finally time to get into PurpleStore!

Windows Phones

You just need Windows 10 Mobile installed. Not sure about anything else. It should just work right away.

PurpleStore time!
