# OLEDX vs Pika! Wallpaper

The clearest difference is ads: OLEDX at none against Pika! Wallpaper's shown. Pika! Wallpaper's advantage is update cadence (every 2 months vs every 10 months) and iOS requirement (10.0 vs 13.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. OLEDX sells 1 one-off in-app purchase and Pika! Wallpaper sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

OLEDX ships an update every 10 months, Pika! Wallpaper every 2 months. The most recent releases landed on September 25, 2026 and September 20, 2026 respectively.
