I built WallTune to fix multi-monitor wallpapers and lock screens. (Native, Shortcuts integration) + 5 Licenses Giveaway!

Hey guys! I’m a solo indie developer, and I’ve been working on a project that I’m really excited (and a bit nervous) to share with you all: WallTune. It’s an app I designed specifically to make multi-monitor setups look amazing without the headache. Here is a quick breakdown: 🚨 The Problem If you use multiple monitors, you probably know the struggle. Setting up your wallpapers and lock screens across different displays is surprisingly clunky. You get everything looking perfect, then you unplug a monitor, plug it back in, and suddenly your whole setup is messed up. The old trial-and-error method of applying a lock screen, locking the Mac to see if it looked right, unlocking it, tweaking it, and repeating was driving me crazy. 🆚 The Comparison Most apps out there force you to choose: they either manage static images, or they manage videos (like Wallper, Wallspace, or Backdrop). WallTune handles both JPG and video wallpapers flawlessly in one place. You don't need to juggle different apps depending on the aesthetic you want today. Additionally, the built-in gallery features hand-curated wallpapers. They are specifically tested to ensure they look stunning in high-resolution, even when stretched across a dual-monitor setup—instead of just pulling unverified random content from the web. Also, unlike other video wallpaper apps that need to run constantly in the background eating RAM, WallTune integrates directly with the native macOS engine—meaning once you set it, you can completely close the app. 🌟 Key Features Match what’s actually on your desk Live editing your lock screen. Adjust how your video looks across all your displays in real-time With WallTune’s Live Editing, you can adjust your monitor settings, crop, and position your media, and see exactly how everything aligns across your entire multi-monitor setup live. Find something that fits your setup Browse image and video wallpapers without leaving the app WallTune includes a Gallery for discovering image and video wallpapers. You can open an item, check its details, preview it on your monitor layout, download it, or add it to a playlist. You can also add your own folders and browse your local files. Wallpapers that follow your Focus Mode Connect a WallTune playlist to a macOS Focus Mode. WallTune can connect playlists to macOS Focus Modes. For example, your desktop can use one playlist while you are working and switch to another when your Personal Focus becomes active. Independent Playlists Need different vibes on different screens? You can set up completely independent playlists. This means your main display can cycle through your work wallpapers while your secondary monitor plays a relaxing background video, giving you total control over each screen individually. Make it part of your Shortcuts Use WallTune actions inside Apple Shortcuts to create your own automations. Use WallTune actions inside Apple Shortcuts to create your own automations. WallTune works with Apple Shortcuts, so you can include your wallpapers in larger routines and personal automations (pick random, next/previous, activate playlist, etc.). And yes, the Lock Screen too Native Lock Screen wallpapers that keep working even when WallTune is closed. Video wallpapers can also be applied to the Mac Lock Screen natively. With multiple displays, you can repeat the same video on each screen or use one composition across the entire setup on spanned mode. You do not need to keep WallTune open in the background! Send wallpapers straight from the web There is no need to manually download files to your Mac and move them around. I've recently built a companion Safari Extension for WallTune (and Chrome / Edge support is coming very soon!). Whenever you find a cool image or video while browsing the web, you can send it directly to your WallTune library or even set it as your current wallpaper in just one click. 💳 Pricing, Link & 🎁 GIVEAWAY!
