# 1DayS vs 壁纸

The clearest difference is ads: 1DayS at none against 壁纸's shown. 壁纸's advantage is update cadence (every 2 weeks vs every 3 weeks) and iOS requirement (10.0 vs 12.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

1DayS ships an update every 3 weeks, 壁纸 every 2 weeks. The most recent releases landed on September 14, 2026 and September 30, 2026 respectively.
