Tweetium is a Windows Universal app. This means that it is an app that has been tweaked to work across Windows desktops, laptops, tablets, and phones. The other side of a universal app is that you get to purchase it only once, and can download it on other devices.
For example, two days ago, I purchased the base app for $2.99 in Windows Phone Store on my Lumia 930. I was billed 480 NGN:
Yesterday, I logged into Windows Store on my laptop and browsed to the app. There were two buttons – “Buy” and “Try”. I clicked the “Buy” button, and it simply downloaded and installed the app without billing me or requesting for payment afresh.
Furthermore, when I launched it on PC, it carried over the Twitter account that I had set up on my phone. Nice touch. Same app; less hassles.
If you ask me, this sort of thing is a big deal. For this sort of seamless experience across Windows devices alone, I am quite excited about Windows 10 and look forward to using it on smartphone and PC. Tablet maybe.
