Neoline

Beautiful, geometric wallpaper. The paid version of this app is highly configurable with multiple options for color, speed, layout, etc. One of the best features is the camera tracking option which will turn the display in to a very convincing 3D image with a level of depth and clarity that is very impressive. When I occasionally hand my phone over to a friend they will always ooh and aah over the display, asking "how does your phone do that!?!". App needs at least 8gb of RAM.

Absolutely love this wallpaper, but while the paid version is super cheap ($1 USD!), it does gatekeep most of the app's features if you have the free version. Also, while the app does have 37 gradients to work with (if you have the paid version), you can't make custom ones, and the one I liked from the previous update seems to have disappeared. The lines in the background also look terrible if you have the background color set to anything higher than black or something really dark.

I really like this wallpaper. I tend to prefer mostly dark backgrounds with some colors moving around and this is a great one for that. The parallax effect when you tilt your phone is really neat, but I didn't find it overly distracting either. You are likely going to want a set of minimalist line icons or at least semi transparent ones with this go keep the illusion at it's best. I paid for it because I plan to use it regularly. I'll likely swap it with the one I was using before occasionally just for variety.
