Verdict

The call

The clearest difference is price: Calculator # at Free against Scientific Calculator++'s $2.99. Calculator # also leads on update cadence (every 2 months vs every 38 months) and ratings volume (36K vs 21). Scientific Calculator++'s advantage is in-app purchases (none vs 6) and ads (none vs shown). On review sentiment and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Scientific Calculator++ holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Calculator # has 36K ratings behind it against 21, so its average is the more settled of the two. Written reviews complicate that: 71% of Calculator #'s written reviews are positive against 67% of Scientific Calculator++'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 2 months, Scientific Calculator++ every 38 months. The most recent releases landed on November 8, 2026 and November 1, 2026 respectively.
