Wallper is a macOS app that brings your desktop to life with animated 4K wallpapers.

It started with a simple frustration - coming from Windows and using Wallpaper Engine, we couldn’t find anything even close for macOS. The existing apps were either outdated, overpriced, full of ads, or required some weird workarounds and heavy setup. We wanted something minimal, elegant, and native.

So we built it ourselves.

Wallper lets you apply animated 4K videos as your Mac desktop background - with just one click. No login required. No subscriptions. No hidden processes eating your CPU. Just a clean and simple app that runs quietly in the background.

You can:

• Choose from a curated library of 600+ 4K video wallpapers

• Upload your own videos (private or public)

• Sync across multiple monitors

• Enable a battery-saving mode

• Use “Wallpaper of the Day” for daily inspiration

• Switch to menu bar mode for minimalism

The app is built fully native with Swift and SwiftUI. All video rendering is optimized to minimize resource usage and avoid battery drain.

We also made it open-source, because we believe in transparency and giving users control. Anyone can explore how it works, suggest improvements, or contribute.

We launched recently, and over 3,000 people already installed Wallper in the first few weeks - just by word of mouth. The feedback has been overwhelmingly positive, which motivates us to keep building and adding new features.

If you’re on macOS and like beautiful, peaceful or inspiring desktops - Wallper might be for you.

It’s free to try, with a paid upgrade for more features (but no pressure, the free version is fully functional). We’d love to hear what you think.
