Using an app like Excel might feel too cumbersome and heavy for such tasks. Now, with Note Calculator, there's no need to worry.

Your work is saved as text, which can be stored as a file and shared with any program that supports text. It couldn't be easier! Additionally, it supports variables, enabling you to perform calculations similar to simple programming: a = 3 b = 2 c = a + b Is it hard to remember or input variables?

ReceptionRating · Positive reviews · Number of ratings

Note Calculator holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: ChatX has 482 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 86% of Note Calculator's written reviews are positive against 88% of ChatX's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
