Verdict

The call

The clearest difference is rating: Cobalt at 5.0 against Iron Prototype's 3.9. Cobalt also leads on update cadence (every 10 days vs monthly). Iron Prototype's advantage is ratings volume (21 vs 3) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
