Verdict

The call

The clearest difference is price: Crazy Math Game at Free against Flashnote Derby's $4.99. Crazy Math Game also leads on rating (5.0 vs 3.8) and iOS requirement (7 vs 16.6). Flashnote Derby's advantage is ratings volume (105 vs 1) and chart position (#103 vs unranked). On ads, in-app purchases, monetization model and device support there is nothing between them.
