# 白噪音 vs AI经期

The clearest difference is ads: AI经期 at none against 白噪音's shown. 白噪音's advantage is update cadence (every 3 days vs monthly) 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. Neither carries in-app purchases, so what you see is what you pay.

白噪音 ships an update every 3 days, AI经期 monthly. Both last shipped on October 27, 2026.
