Verdict
The clearest difference is ads: Eventsential at none against COST Events's shown. Eventsential also leads on update cadence (every 5 weeks vs every 5 months) and ratings volume (25 vs 1). COST Events's advantage is rating (4.0 vs 3.5). On price, in-app purchases, monetization model and device support there is nothing between them.
