As answered by people managing Project Euler and Walyro.
Walyro's answer:
Most Mac wallpaper apps hand you a gallery to browse. Walyro starts from your own footage instead. You point it at your MP4 or MOV clips and it plays them as live wallpapers up to 4K, with a different one on each display. The whole library stays on your Mac, with no online catalog, no account, and no tracking. It's a native Swift and SwiftUI app, so it pauses on fullscreen and eases off on battery to stay light on the CPU.
Walyro's answer:
Choose Walyro if you want your own videos on your desktop rather than a prebuilt gallery, and if you'd rather keep everything on your Mac. Nothing uploads, there's no account, and there's no subscription: you download it free and pay once to unlock the full app. It still covers what the others are known for, per-display wallpapers, up to 4K, and playlists that rotate on their own, while staying native and light on the CPU. If what you want is a large online catalog of ready-made wallpapers, a gallery-first app may suit you better. Walyro is for people who want to use their own clips.
Walyro's answer:
Mac users who want their desktop to feel personal and who care about keeping files on their own machine. That includes people coming from Wallpaper Engine on Windows who want a native Mac option, multi-monitor setups that want a different scene on each screen, and anyone with their own clips (footage they shot, renders, or edits) who would rather use those than pick from a stock library. The common thread is wanting control over the wallpaper without sending anything to the cloud.
Walyro's answer:
I wanted my own videos living on my desktop without uploading them to someone's cloud or making yet another account. The Mac apps I tried were built around their own galleries, and Wallpaper Engine, the app people always point to, doesn't run on Mac at all. So I built the one I wanted: point it at your own clips, keep the whole library on the device, and make it feel native instead of a web wrapper. That starting point shaped the rest, from previewing each display before you apply a wallpaper to pausing playback the moment you go fullscreen or switch to battery.
Walyro's answer:
Walyro is a fully native macOS app, with no Electron or other cross-platform runtime. It's written in Swift with SwiftUI and AppKit for the interface, Combine for state, and AVFoundation and AVKit for video playback. In-app purchases use StoreKit 2, and launch-at-login uses ServiceManagement.
Walyro's answer:
Walyro is a consumer app used by individual Mac users, so there are no named business customers to list.
