# CalKeyboard vs CalcKey

The clearest difference is rating: CalcKey at 4.0 against CalKeyboard's 3.4. CalcKey also leads on update cadence (every 3 weeks vs every 8 months). CalKeyboard's advantage is review sentiment (50% vs 33%). 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 CalcKey sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

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.

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.
