Proton - Icon Pack is a personalization app for Android devices developed by PhunktasticDesigns. The app boasts a mix of multicolored icons with a shadow for depth, making it stand out from the typical flat designs. The developer mentions that the set took two months to create, ensuring that only the icons that meet their personal taste and satisfaction are published.

The app includes over 3,400 HD icons (256x256), 32 matching HD cloud wallpapers, and support for various launchers such as Action, Adw, AdwEX, Apex, Atom, Aviate, GO, Next, Nova, Smart, and Solo. The app also features icon masking for un-themed icons, a dynamic calendar, alternative icons to choose from, and regular updates.
