Prism

Prism is a beautiful open-source wallpapers app for Android. It is built with Dart on top of Google's Flutter Framework.

Prism offers an exclusive collection of wallpapers that are beautifully hand-crafted for your very specific device. This exclusive collection is hand-picked from all around the world to give you the best illustration, graphics, and photographs that look amazing in any setup that you want. Now Prism also offers an exclusive range of home screen setups, that you can simply apply. Each setup includes a wallpaper, an icon pack and a widget.

Prism relies on its Community and WallHaven and Pexels APIs as its source of beautiful and large collection of Wallpapers. By utilizing their API, it provides the user with a fast and smooth experience filled with subtle animations and minimal design. The main goal of Prism is to make the smartphone customization experience, smooth and easy, yet giving the users amazing wallpapers, and features like downloading infinite (as much your storage allows) wallpapers or sharing the ones they like with others.

Now users can upload wallpapers, which will be shown in the Community section. They can also view the wallpapers they uploaded in the Profile section. We generally take upto 24 hours for reviewing every wallpaper, but premium users get their wallpapers reviewed instantly.

Prism offers a never-ending feed of wallpapers on its home screen. It also has a Curated section that is filled with the best photos/wallpapers updated every day. It also features categories like Abstract, Nature, 4K, Art, Landscape, Minimal, Space, Neon, etc. if you are into these. Then it allows one to find wallpapers based on colors, i.e. you can find wallpapers with a color that matches your icons or home screen setup. Not even that, it also shows you a palette of colors from any wallpaper in the app, on clicking which you can find wallpapers of that specific color.

Main features like finding, downloading and setting up wallpapers don't require Google Sign In, while features like Favourites require you to sign up using Google. This signup is facilitated by Google Firebase, so it is secure and we only get your name, email, and profile photo for identification purposes. The app also has Dark Mode, if you want to save your phone's battery while getting in love with those wallpapers. The app also allows users to share wallpapers with others by giving them a unique link for every wallpaper, using Firebase Dynamic Links so that anyone can directly view the wallpaper.
