# Data Structure Display vs 数据结构与算法

The clearest difference is review sentiment: 数据结构与算法 at 100% against Data Structure Display's 62%. 数据结构与算法 also leads on rating (5.0 vs 4.5) and iOS requirement (9.0 vs 13.0). Data Structure Display's advantage is ads (none vs shown) and ratings volume (676 vs 1). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Data Structure Display sells 1 one-off in-app purchase and 数据结构与算法 sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

数据结构与算法 holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Data Structure Display has 676 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 62% of Data Structure Display's written reviews are positive against 100% of 数据结构与算法's.
