Verdict

The call

The clearest difference is ads: DieselCalcs at none against Compound Interest Calc's shown. DieselCalcs also leads on monetization model (free vs free with in-app purchases). Compound Interest Calc's advantage is ratings volume (6.7K vs 3) and iOS requirement (15.6 vs 18.4). On price, rating, update cadence and in-app purchases there is nothing between them.
