ReceptionRating · Positive reviews · Number of ratings

FastCalc holds the better App Store score, 4.8 against 4.5. Both are backed by a comparable volume of ratings — 4 and 15 respectively. Written reviews complicate that: 80% of FastCalc's written reviews are positive against 100% of Pro Note's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

FastCalc ships an update every 5 months, Pro Note monthly. The most recent releases landed on October 7, 2026 and September 30, 2026 respectively.
