What's the story behind your product?

Wallper's answer

Wallper started as a weekend project. After switching from Windows, we couldn’t believe how limited macOS was when it came to live wallpapers — there just wasn’t a clean, native solution like Wallpaper Engine. We built the first version just for ourselves, to bring our desktops to life again. But as we shared it with friends and online communities, it quickly turned into something much bigger. What began as a personal fix is now a fully featured app used by thousands of Mac users around the world.

Which are the primary technologies used for building your product?

Wallper is built entirely in Swift & SwiftUI. Everything is optimized for macOS with no Electron or cross-platform layers.
