Verdict

The call

The clearest difference is review sentiment: Calculator + at 85% against Scientific Calculator Pro's 0%. Calculator + also leads on ratings volume (10K vs 1). Scientific Calculator Pro's advantage is in-app purchases (none vs 10) and ads (none vs shown). On price, update cadence and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Scientific Calculator Pro holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Calculator + has 10K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 85% of Calculator +'s written reviews are positive against 0% of Scientific Calculator Pro's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Calculator + ships an update every 5 days, Scientific Calculator Pro every 6 days. The most recent releases landed on November 5, 2026 and November 2, 2026 respectively.
