# CPA vs Tro

The clearest difference is ads: Tro at none against CPA's shown. Tro also leads on update cadence (every 6 weeks vs every 8 months) and iOS requirement (9.0 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.

CPA ships an update every 8 months, Tro every 6 weeks. The most recent releases landed on October 16, 2026 and October 26, 2026 respectively.
