Verdict
The clearest difference is price: Debit & Credit at Free against Adding Machine 10Key iPhone's $2.99. Debit & Credit also leads on ratings volume (2.3K vs 130) and rating (4.8 vs 4.6). Adding Machine 10Key iPhone's advantage is in-app purchases (none vs 3) and chart position (#66 vs unranked). On review sentiment, update cadence and ads there is nothing between them.

Written reviews complicate that: 95% of Adding Machine 10Key iPhone's written reviews are positive against 89% of Debit & Credit's, so the app with the better star average is not the one people write more warmly about.
