Verdict
The clearest difference is review sentiment: BitSet at 100% against DSA Master's 13%. BitSet also leads on rating (5.0 vs 4.2) and ads (none vs shown). DSA Master's advantage is ratings volume (35 vs 1). On price, in-app purchases, monetization model 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 and BitSet sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
BitSet holds the better App Store score, 5.0 against 4.2. 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: 13% of DSA Master's written reviews are positive against 100% of BitSet's.
DSA Master ships an update weekly, BitSet every 3 days. The most recent releases landed on September 7, 2026 and June 6, 2026 respectively.
