# Data Structures vs DSA Master

The clearest difference is review sentiment: Data Structures at 86% against DSA Master's 13%. Data Structures also leads on in-app purchases (none vs 1) and ads (none vs shown). DSA Master's advantage is rating (4.2 vs 3.1) and update cadence (weekly vs every 3 months). On price and device support there is nothing between them.

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

DSA Master holds the better App Store score, 4.2 against 3.1. That said, the two scores are not equally well evidenced: DSA Master has 35 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 13% of DSA Master'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, DSA Master weekly. The most recent releases landed on September 23, 2026 and September 22, 2026 respectively.
