Verdict
The clearest difference is rating: Mini LAB at 4.7 against COSA's 3.7. Mini LAB also leads on ratings volume (60 vs 3). COSA's advantage is update cadence (every 3 months vs every 24 months) and iOS requirement (11.0 vs 18). On price, ads, in-app purchases and monetization model there is nothing between them.
