Microsoft has started delivering rapidly on the promise of Universal apps on Windows Phone 8.1, with a number of cross-platform apps already showing up.
The apps, which are labelled “Made for Windows Phones and Windows PCs”, allows users to pay once and install on both platforms.
This can already be seen in one app, Halo: Spartan Assault, which if you purchased it for the phone can be installed on your PC and vice versa.
Other apps with early support include Shazam, Hexic, Microsoft Mahjong, Microsoft Solitaire Collection, Wordament.
The feature will increase the value of apps for Windows Phone and Windows 8 users, and make them more likely to pay for them, which should ultimately help developers make more money.
