ReceptionRating · Positive reviews · Number of ratings

CalcKey holds the better App Store score, 4.0 against 3.4. Both are backed by a comparable volume of ratings — 5 and 10 respectively. Written reviews complicate that: 50% of CalKeyboard's written reviews are positive against 33% of CalcKey's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

CalKeyboard ships an update every 8 months, CalcKey every 3 weeks. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
