Verdict
The clearest difference is rating: LumiSource at 4.7 against AP Test Ready's 3.4. LumiSource also leads on ratings volume (46 vs 9) and iOS requirement (14.0 vs 18.2). AP Test Ready's advantage is update cadence (fortnightly vs every 3 months). On price, ads, in-app purchases and monetization model there is nothing between them.
