# Wallpapers 4K vs Backdrop

The clearest difference is update cadence: Backdrop at every 3 days against Wallpapers 4K's every 3 weeks. Backdrop also leads on review sentiment (100% vs 88%). Wallpapers 4K's advantage is monetization model (free vs freemium) and ratings volume (137 vs 5). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Wallpapers 4K sells 1 in-app purchase, starting at $0.99 per 7 days and Backdrop sells 1 in-app purchase, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for Wallpapers 4K against 4.6 for Backdrop. That said, the two scores are not equally well evidenced: Wallpapers 4K has 137 ratings behind it against 5, so its average is the more settled of the two. Written reviews are what separate them: 88% of Wallpapers 4K's written reviews are positive against 100% of Backdrop's.

Wallpapers 4K ships an update every 3 weeks, Backdrop every 3 days. The most recent releases landed on October 16, 2026 and October 4, 2026 respectively.
