When it comes to Windows 10 and Windows 10 Mobile, the promise of Universal Apps is a big part of the equation for many users. One popular request we have seen is for a wallpaper changer. After all, nothing is more personal than the image on your lock screen, desktop or Start screen.

Brilli Wallpaper Changer is a fascinating app for a few reasons. For one, it is universal. That means the app runs on your Windows 10 PC, tablet, Surface and phone. The other is that it can change your lockscreen, desktop and Start screen automatically every 15 minutes (or more).

The app

Brilli is a free app in the Windows Store although there is an optional $1.49 in-app purchase to unlock some features. Those unlocked features include:

  • Unlimited collections (Free mode is just 2)
  • Up to 200 files per collection (Free is just 30)

Plus, you get that rosy feeling knowing that you are helping a developer.

In terms of size, you are looking at a 62 MB file, which is in line with universal apps these days.

The app's design uses the hamburger button for navigation. However, the developer noted on Reddit they will be adding a swipe option for Phone users in the next update. Otherwise, the app looks very much like a native Windows 10 app akin to Photos.

Features and what it can do

By default, Brilli uses Bing images for its source. You can, of course, create your collection that lets you add your own images from your phone or PC. You can name the collection and depending if you are using the free or paid version, each collection can range from 30 to 200 images.

The app can auto-change your wallpaper for both the lockscreen and desktop/Start screen. Intervals can range from every 15 minutes up to once a day giving you plenty of options in between. There is also a random or sequential choice for each collection to help add some spontaneity.

Finally, you can opt to use the same image for the lock and Start screen to make them match.


Brilli is quite a fantastic app. I've been using it all morning on my Lumia 1520 and Windows 10 PCs. Obviously the best part of the app is the auto-changer that keeps your device looking new each time you turn it on. The default Bing images are very popular and make it a worthy starting point for most users, although those with peculiar tastes will very likely create their own albums.

The $1.49 in-app purchase works well too. I was able to buy the app through the PC version and the app on the phone was unlocked as well. I did have a syncing issue with the name of one of my albums, but I'll chalk that up to an early bug.

If you have been looking for an auto-wallpaper changer, definitely try out Brilli. It works well, has a great design and you can't go wrong with it being universal.
