# 微差事 vs CTR众拍

The clearest difference is ads: CTR众拍 at none against 微差事's shown. CTR众拍 also leads on update cadence (every 3 weeks vs every 2 months) and iOS requirement (8.0 vs 11.0). 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.

微差事 ships an update every 2 months, CTR众拍 every 3 weeks. The most recent releases landed on September 27, 2026 and October 1, 2026 respectively.
