wallpaperOS

wallpaperOS started as a creative outlet, not a product. I wanted to explore generative art and needed a reason to learn the math behind it. The wallpaper format gave the project a clear container - something visual, self-contained, and worth looking at every day.

• The idea came from wanting something alive on my screen between meetings and on the subway - not distracting, just present
• Mies van der Rohe's "less is more" and Steve Jobs' "simplicity is the ultimate sophistication" shaped the entire design philosophy
• Existing wallpaper apps felt bloated with social features, ads, and video loops that drained battery for no reason
• Generative art projects showed what was possible with pure math - I wanted to bring that to a native app experience

I did not set out to build a product. I set out to learn something, and the app gave it shape.

I targeted iOS 26 exclusively because the Liquid Glass and latest SwiftUI Canvas APIs were essential to the vision. Backward compatibility would have meant compromising the rendering.

• Each gallery uses its own generative algorithm - trigonometric waves, vector fields, fractal recursion, and procedural grids
• Getting the math right was the hardest part - a flow field that looks organic instead of random comes down to tweaking one variable at a time until it clicks
• Glass effects and the latest SwiftUI APIs made iOS 26 the minimum - the visual quality would not have been possible on older versions
• The clock overlay supports drag repositioning, multiple fonts, and format options so the wallpaper doubles as a functional lock screen
• Everything stays on-device with no backend, no sync, and no accounts

Each gallery shipped rooted in a different mathematical concept.

The generative algorithms were the biggest challenge. Making them look good on a phone screen meant understanding every parameter. Not just copying code, but learning why sine waves layer the way they do and how fractal branching produces natural-looking trees.

• Early prototypes exposed every parameter - amplitude, frequency, speed, color count - and it felt like a science experiment, not a wallpaper app. Stripping it back to a few presets was the right call
• The galleries draw from art history - Mondrian's grids, Molnar's geometric abstractions, and flow field algorithms
• The clock overlay started as an afterthought but became one of the most-used features during testing
• Building something creative taught me differently than building a utility - there is no conversion metric for "does this feel right when you glance at your phone"

Simplicity is the ultimate sophistication.

I do not collect, store, or transmit any personal data to external servers. Everything stays on your device. wallpaperOS requires no accounts, no registration, and no login. You can start using it immediately without providing any personal information.

I do not collect personal identification information, usage analytics, device identifiers, location data, or any user-generated content. The app uses no third-party services, no analytics platforms, no advertising networks, no social media SDKs, and no crash reporting tools.

All settings are stored locally on your device using Apple's AppStorage framework and protected by platform sandboxing. Your data never leaves your device, is not backed up to any cloud service, and is completely deleted when you uninstall the app.

You have complete control over your data at any time by uninstalling the app. wallpaperOS complies with GDPR, CCPA, and COPPA by design through my no-data-collection architecture. For privacy questions, contact privacy@mlot.ai.
