# Scientific Calculator Pro vs Calculator +ㅤ

The clearest difference is review sentiment: Calculator +ㅤ at 47% against Scientific Calculator Pro's 0%. Calculator +ㅤ also leads on ratings volume (4.6K vs 1). Scientific Calculator Pro's advantage is in-app purchases (none vs 6) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. Calculator +ㅤ sells 6 in-app purchases, starting at $2.99 per 7 days. Scientific Calculator Pro asks for nothing beyond the download.

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 +ㅤ has 4.6K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of Scientific Calculator Pro's written reviews are positive against 47% of Calculator +ㅤ's, so the app with the better star average is not the one people write more warmly about.

Scientific Calculator Pro ships an update every 6 days, Calculator +ㅤ fortnightly. Both last shipped on October 30, 2026.
