# 答案之书 vs Matrix Alarm

The clearest difference is rating: Matrix Alarm at 5.0 against 答案之书's 4.1. Matrix Alarm also leads on ads (none vs shown). 答案之书's advantage is ratings volume (11 vs 2). On price, review sentiment, update cadence and in-app purchases there is nothing between them.

Both are free to download. 答案之书 sells 1 one-off in-app purchase and Matrix Alarm sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Matrix Alarm holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: 答案之书 has 11 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
