# Data Structures vs Data Structure Display

The clearest difference is rating: Data Structure Display at 4.5 against Data Structures's 3.1. Data Structure Display also leads on ratings volume (676 vs 7). Data Structures's advantage is in-app purchases (none vs 1) and review sentiment (86% vs 62%). On price, ads and device support there is nothing between them.

Both are free to download. Data Structure Display sells 1 one-off in-app purchase. Data Structures asks for nothing beyond the download.

Data Structure Display holds the better App Store score, 4.5 against 3.1. That said, the two scores are not equally well evidenced: Data Structure Display has 676 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 86% of Data Structures's written reviews are positive against 62% of Data Structure Display's, so the app with the better star average is not the one people write more warmly about.

Data Structures ships an update every 3 months, Data Structure Display every 5 months. The most recent releases landed on September 23, 2026 and October 3, 2026 respectively.
