# DSA Master vs LeetCards

The clearest difference is rating: DSA Master at 4.2 against LeetCards's 1.0. DSA Master also leads on update cadence (weekly vs every 3 weeks) and ratings volume (35 vs 4). LeetCards's advantage is ads (none vs shown) and iOS requirement (13.4 vs 16.2). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. DSA Master sells 1 one-off in-app purchase and LeetCards sells 3 in-app purchases, starting at $9.00 per month. Whichever you choose, the download price is not the number that matters.

DSA Master holds the better App Store score, 4.2 against 1.0. That said, the two scores are not equally well evidenced: DSA Master has 35 ratings behind it against 4, so its average is the more settled of the two.

DSA Master ships an update weekly, LeetCards every 3 weeks. The most recent releases landed on September 7, 2026 and September 17, 2026 respectively.
