# Data Structure Display vs AlgoCode Learn

The clearest difference is rating: Data Structure Display at 4.5 against AlgoCode Learn's 3.4. Data Structure Display also leads on ratings volume (676 vs 7) and iOS requirement (13.0 vs 15.1). AlgoCode Learn's advantage is in-app purchases (none vs 1) and update cadence (every 6 days vs every 5 months). On price, review sentiment, ads and device support there is nothing between them.

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

Data Structure Display holds the better App Store score, 4.5 against 3.4. 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 point the same way: 62% of Data Structure Display's written reviews are positive against 60% of AlgoCode Learn's.

Data Structure Display ships an update every 5 months, AlgoCode Learn every 6 days. The most recent releases landed on September 24, 2026 and June 1, 2026 respectively.
