Questions & Answers

As answered by people managing LeetCode and Wallper.

What makes your product unique?

Wallper's answer:

Wallper combines beautiful live wallpapers with native macOS performance. No clunky wrappers, no subscriptions. It just works smoothly and with complete control for every screen.

Why should a person choose your product over its competitors?

Most alternatives are either outdated, heavy on resources, or require a login. Wallper is fast, lightweight, fully local, and respects your privacy. Plus, it’s designed specifically for macOS.

How would you describe the primary audience of your product?

Wallper's answer:

Mac users who care about aesthetics, productivity, and simplicity. Creatives, developers, designers - anyone who wants their desktop to feel alive and personal.

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's answer:

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

Who are some of the biggest customers of your product?

Wallper's answer:

Used by teams at indie studios and design agencies
