Verdict
The clearest difference is in-app purchases: Wonderous at none against Currency's 3. Wonderous also leads on ads (none vs shown) and review sentiment (100% vs 80%). Currency's advantage is ratings volume (79K vs 20) and chart position (#88 vs unranked). On price, rating and device support there is nothing between them.
