Verdict
The clearest difference is price: Calculator for iPad₊ at Free against Calculator's $1.99. Calculator for iPad₊ also leads on rating (4.5 vs 4.0) and update cadence (monthly vs every 11 months). Calculator's advantage is in-app purchases (none vs 7) and ads (none vs shown). On device support and iOS requirement there is nothing between them.
