VisiMarks holds the better App Store score, 4.5 against 3.8. That said, the two scores are not equally well evidenced: VisiMarks has 359 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 63% of Classicalc calculator's written reviews are positive against 60% of VisiMarks's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Classicalc calculator ships an update every 20 months, VisiMarks every 2 months. Both last shipped on November 6, 2026.
