Verdict
The clearest difference is price: Calculator at Free against Big Button Calculator Pro's $9.99. Big Button Calculator Pro's advantage is ads (none vs shown) and update cadence (every 2 months vs every 13 months). On review sentiment, ratings volume, in-app purchases and device support there is nothing between them.
