# 准省 vs 触联

The clearest difference is ads: 触联 at none against 准省's shown. 触联 also leads on update cadence (every 3 weeks vs every 7 months). 准省's advantage is iOS requirement (12.0 vs 15.1). 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.

准省 ships an update every 7 months, 触联 every 3 weeks. The most recent releases landed on October 19, 2026 and October 5, 2026 respectively.
