Verdict
The clearest difference is review sentiment: CalKeyboard at 50% against Calculator's 0%. Calculator's advantage is rating (4.3 vs 3.4) and update cadence (every 4 days vs every 8 months). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. CalKeyboard sells 1 one-off in-app purchase and Calculator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Calculator holds the better App Store score, 4.3 against 3.4. Both are backed by a comparable volume of ratings — 5 and 9 respectively. Written reviews complicate that: 50% of CalKeyboard's written reviews are positive against 0% of Calculator's, so the app with the better star average is not the one people write more warmly about.
CalKeyboard ships an update every 8 months, Calculator every 4 days. The most recent releases landed on September 9, 2026 and July 5, 2026 respectively.
