Walpium: Lock Wallpapers 4K HD

Walpium is a wallpaper application for iPhone that turns your lock screen and home screen into something personal. Rather than hunting through web galleries, you swipe through one endless, curated feed of more than 10,000 designs covering aesthetic, minimalist, abstract, dark/AMOLED, neon, nature, anime, and 3D art styles. AI-generated and AI-customized pieces sit alongside hand-picked wallpapers, giving the feed a constantly refreshed feel.

What makes it practical is the preview system: every wallpaper can be shown on a lock screen mock-up that displays your own date and time, so you see exactly how it will look before committing. When you like one, you save it to Photos or share it in a tap, with downloads that preserve full 4K quality. The feed loads the next page while you view the current one, and it shows a retry prompt instead of an empty screen if your connection drops.

Walpium is free to use with one wallpaper save per day; the Pro upgrade removes ads and unlocks unlimited saves. Subscriptions are handled through Apple's standard in-app purchase system, with a weekly or yearly option. The app requires iOS 17 or later.
