# 择吉程序 vs 一体化系统

The clearest difference is in-app purchases: 一体化系统 at none against 择吉程序's 1. 一体化系统 also leads on iOS requirement (9.0 vs 16). On price, ads and device support there is nothing between them.

Both are free to download. 择吉程序 sells 1 one-off in-app purchase. 一体化系统 asks for nothing beyond the download.
