# Algorithms vs Data Structure Display

The clearest difference is review sentiment: Algorithms at 91% against Data Structure Display's 62%. Algorithms also leads on update cadence (every 6 weeks vs every 5 months) and rating (4.7 vs 4.5). Data Structure Display's advantage is ratings volume (676 vs 101). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Algorithms sells 1 one-off in-app purchase and Data Structure Display sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Algorithms holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Data Structure Display has 676 ratings behind it against 101, so its average is the more settled of the two. Written reviews point the same way: 91% of Algorithms's written reviews are positive against 62% of Data Structure Display's.

Algorithms ships an update every 6 weeks, Data Structure Display every 5 months. The most recent releases landed on October 8, 2026 and October 3, 2026 respectively.
