# Algorithms HQ vs DSA Master

The clearest difference is review sentiment: Algorithms HQ at 100% against DSA Master's 13%. Algorithms HQ also leads on in-app purchases (none vs 1) and ads (none vs shown). DSA Master's advantage is update cadence (weekly vs every 16 months) and ratings volume (35 vs 1). On price, device support and iOS requirement there is nothing between them.

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

DSA Master holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: DSA Master has 35 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Algorithms HQ'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.

Algorithms HQ ships an update every 16 months, DSA Master weekly. The most recent releases landed on September 8, 2026 and September 7, 2026 respectively.
