An app that looks like the regular calculator, but all the operations work in a modulus. Powers and inverses in a modulus are also supported (division is done by multiplying by the inverse). Tap the handy "mod" indicator to switch the modulus.

Verdict
The clearest difference is in-app purchases: Modulus Calculator at none against Calculator +'s 12. Modulus Calculator also leads on ads (none vs shown) and review sentiment (100% vs 85%). Calculator +'s advantage is ratings volume (10K vs 8). On price and device support there is nothing between them.

Both are free to download. Calculator + sells 12 in-app purchases, starting at $4.99 per month. Modulus Calculator asks for nothing beyond the download.
Modulus Calculator holds the better App Store score, 4.8 against 4.6.

Written reviews point the same way: 85% of Calculator +'s written reviews are positive against 100% of Modulus Calculator's.
