Verdict

The call

The clearest difference is update cadence: iPulsaret at every 3 weeks against Classic FX's every 2 months. iPulsaret also leads on rating (4.8 vs 4.6) and price ($9.99 vs $12.99). Classic FX's advantage is review sentiment (87% vs 78%) and iOS requirement (13.4 vs 15.6). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
