# Reckon vs Eureka

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.

Both are free to download. Reckon sells 1 one-off in-app purchase and Eureka sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Reckon ships an update every 7 months, Eureka every 4 weeks. The most recent releases landed on September 23, 2026 and October 4, 2026 respectively.
