# Prokom vs 大夏书系

The clearest difference is update cadence: 大夏书系 at monthly against Prokom's every 4 months. Prokom's advantage is iOS requirement (12.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Prokom sells 5 one-off in-app purchases and 大夏书系 sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Prokom ships an update every 4 months, 大夏书系 monthly. The most recent releases landed on September 19, 2026 and September 25, 2026 respectively.
