Abstruct is an app that was developed by Hampus Olsson, the artist who creates the OnePlus official wallpapers. Abstruct gives you access to more than 300 exclusive wallpapers that are only available in this app.
The wallpapers that are included in Abstruct are divided into nine different categories, although all of them share a common style (which is obvious). Four of these categories are free, but you'll have to pay if you want to access the other five. There are more than 300 different wallpapers in total (between the free and premium options).
In order to apply any of the wallpapers, all you have to do is tap on the corresponding button. When you do that, you can choose whether you want to use it as a lock screen, wallpaper or both.
Abstruct is an excellent wallpaper app that helps you customize your Android smartphone using high-quality images. The best part is that more free and premium wallpapers are added every time the app is updated.
