# 学信网 vs 安全员练题狗

The clearest difference is review sentiment: 安全员练题狗 at 90% against 学信网's 6%. 安全员练题狗 also leads on rating (5.0 vs 3.9) and iOS requirement (10.0 vs 13.0). 学信网's advantage is in-app purchases (none vs 9) and update cadence (every 4 weeks vs every 6 months). On price, ads and device support there is nothing between them.

Both are free to download. 安全员练题狗 sells 9 one-off in-app purchases. 学信网 asks for nothing beyond the download.
