Verdict

The call

The clearest difference is price: Dev Calc at Free against Pascal's $2.99. Dev Calc also leads on iOS requirement (13.0 vs 17.6). Pascal's advantage is rating (4.0 vs 2.0) and ads (none vs shown). On in-app purchases, monetization model and device support there is nothing between them.
