Verdict

The call

The clearest difference is review sentiment: Delta at 67% against DSA Master's 13%. Delta also leads on ads (none vs shown) and device support (4 vs 2). DSA Master's advantage is rating (4.2 vs 3.1) and update cadence (weekly vs monthly). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. Delta sells 3 one-off in-app purchases and DSA Master sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

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: 67% of Delta'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.

UpkeepUpdate frequency

Delta ships an update monthly, DSA Master weekly. The most recent releases landed on September 29, 2026 and September 22, 2026 respectively.
