# 侦探推理 vs C++程序设计

The clearest difference is in-app purchases: 侦探推理 at none against C++程序设计's 1. C++程序设计's advantage is update cadence (every 3 months vs every 52 months) and iOS requirement (12.0 vs 14.0). On price, ads and device support there is nothing between them.

Both are free to download. C++程序设计 sells 1 one-off in-app purchase. 侦探推理 asks for nothing beyond the download.

侦探推理 ships an update every 52 months, C++程序设计 every 3 months. The most recent releases landed on October 7, 2026 and October 22, 2026 respectively.
