Verdict

The call

The clearest difference is rating: Know at 5.0 against DSA Master's 4.2. Know also leads on ads (none vs shown) and iOS requirement (13.0 vs 16.2). DSA Master's advantage is ratings volume (35 vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.
