Verdict
The clearest difference is rating: DSA Master at 4.2 against Learn Java's 2.0. DSA Master also leads on update cadence (weekly vs every 3 months) and ratings volume (35 vs 1). Learn Java's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. DSA Master sells 1 one-off in-app purchase. Learn Java asks for nothing beyond the download.
DSA Master holds the better App Store score, 4.2 against 2.0. 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 point the same way: 0% of Learn Java's written reviews are positive against 13% of DSA Master's.
Learn Java ships an update every 3 months, DSA Master weekly. The most recent releases landed on June 1, 2026 and September 7, 2026 respectively.
