# The Data Channel vs DSA Master

The clearest difference is rating: The Data Channel at 5.0 against DSA Master's 4.2. The Data Channel also leads on ads (none vs shown) and device support (4 vs 2). DSA Master's advantage is monetization model (free with in-app purchases vs subscription) and update cadence (weekly vs every 6 weeks). On price and in-app purchases there is nothing between them.

Both are free to download. The Data Channel sells 2 in-app purchases, starting at $14.99 per month and DSA Master sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

The Data Channel 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 2, so its average is the more settled of the two.

The Data Channel ships an update every 6 weeks, DSA Master weekly. The most recent releases landed on September 23, 2026 and September 22, 2026 respectively.
