Verdict

The call

The clearest difference is ads: Reckon at none against Eureka's shown. Reckon also leads on review sentiment (100% vs 77%). Eureka's advantage is update cadence (every 4 weeks vs every 7 months). On price, in-app purchases, monetization model and device support there is nothing between them.
