Verdict

The call

The clearest difference is in-app purchases: Our Interview at none against DSA Master's 1. Our Interview also leads on ads (none vs shown) and iOS requirement (12.0 vs 16.2). DSA Master's advantage is update cadence (weekly vs every 7 months). On price and device support there is nothing between them.
