I have Ciri on my desktop. Who played "The Witcher. Wild Hunt" and in love, the game from the trilogy, he will understand who I am. Well, in general, I don't use any websites or launchers for a smartphone to find cool wallpapers I'm looking for everything either through communities in VK or through Yandex.Pictures.
Quite a tolerable site with a huge number of photos / art in different categories, from anime to abstract images, often in 4k quality
Go to some beautiful place and take a picture yourself. Or go over old photos. Much more pleasant sensations than when delving into other people's drawings or photos. I now use a frame of the Gorely volcano in Kamchatka, once I took it while there.
For Android OS, I can recommend the following applications that have a nice interface and, in fact, very beautiful wallpapers:
Frame - Wallpapers
Backdrops - Wallpapers
I think it's unnecessary to describe.
Yes, in the same Pinterest you can find wallpapers for a smartphone. One has only to enter keywords and that's it.
For my phone, I'm always looking there ..........
I go to tumblr from time to time, because in my opinion you can sometimes stumble upon amazingly beautiful photographs / art there. And the plus is that you can search for pictures by any tag or word.
For iOS I can recommend WLPPR. This application proposes to use high quality satellite images of the Earth as wallpaper. By the way, this is one of the most beautiful applications on iOS.
No matter how much I tried to find wallpaper on purpose, I never succeeded. Many directories with the same type of images, among which it is difficult to choose something specific. I gave up this stupid idea. In my opinion, it makes sense to view the work of contemporary artists or thematic resources that interest you. Maybe you are fond of films, anime or architecture, you will definitely be hooked on some kind of picture. For example, a couple of years ago, when I was fond of biology, I stumbled upon the work of the artist Eleanor Lutz, during this time I changed two phones, but this image is still with me and still not tired of it)
In good resolution
Recommend Unsplash | Free High Resolution Photos
A large number of unrealistically beautiful photos in modern processing. All photos are in 2k and higher quality, you will not be ashamed to put them as wallpaper on both your phone and your PC.
appstore has an application called "Wallpaper". There are a lot of ads, but the pictures are of high quality and there are a lot of them, categorized.
I like Papers.co, I tried a lot of applications and ended up with this. The catalog is not very convenient, but I like the photos themselves.
