Verdict

The clearest difference is ads: Crazy John at none against BlamBlam.io's shown. Crazy John also leads on iOS requirement (3.0 vs 15.0). BlamBlam.io's advantage is review sentiment (100% vs 66%) and update cadence (every 2 days vs every 4 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.
