Everything in the app

Nell 4K Wallpaper is a single product. These are the functions you will find in the current Android build — described as they actually work.

Discover

The Discover tab is a category browser. Swipe between collections, scroll a two-column grid, and load more pages as you go. The catalog travels with the app; images load when you look at them.

Seventeen collections

Wallpapers are grouped into Animal, Food, Art, Makeup, Exercise, Health, Travel, Plant, Building, Others, Life, Fashion, Car, Cutepet, News, Fishing, and Emotion. Each collection is its own list you can page through independently.

Full-screen preview

Tap a thumbnail to open it edge to edge. Swipe left or right for the next wallpaper in that collection. Tap the picture to hide or show the toolbar. A first-run hint explains the swipe.

Set as wallpaper

From preview, choose Home screen, Lock screen, or Home and lock screen, then confirm. Nell 4K Wallpaper applies the image through Android’s wallpaper service. A success screen appears when it is done.

Favorites

Heart a wallpaper to keep it in the Favorites tab. Open the list later, jump back into preview, or select several items and delete them. Favorites live only on your device.

Save to gallery

Download writes a JPEG into your Photos album named “Nell 4K Wallpaper”. The same item appears in the Downloads tab so you can review or remove the in-app record. On older Android versions, saving asks for storage permission.

Share hands a JPEG to Android’s system share sheet so you can send it with Messages, Drive, or any app you pick. Nell 4K Wallpaper does not post on your behalf.

Recommended for you

When Favorites or Downloads are empty, and again after you set a wallpaper, the app shows a short recommended row drawn from the catalog so you can keep browsing.

About

The About tab shows the Nell 4K Wallpaper icon, app name, and version. Privacy Policy opens as a second screen inside the app. There is no overflow menu of extra settings.

Private by design

No account, no ads, no analytics SDK. Local lists and preferences stay on the device. See the Privacy Policy for how image requests and gallery saves work.

Three steps from the home grid to a new Home or Lock screen.

Step 1

Choose a collection

Start in Discover, swipe to a category, and scroll the grid.

Step 2

Preview full screen

Tap a still, swipe for more in the same list, tap to hide the chrome.

Step 3

Set, save, or share

Apply to Home, Lock, or both — or favorite, download, or share the JPEG.
