The clearest difference is price: Calculator₊ at Free against Calculator!'s $0.99. Calculator₊ also leads on ratings volume (1.7M vs 4.3K) and update cadence (every 3 weeks vs every 3 months). Calculator!'s advantage is ads (none vs shown) and review sentiment (86% vs 63%). On rating, in-app purchases and monetization model there is nothing between them.
