# Calculator vs Calculator +ㅤ

The clearest difference is price: Calculator +ㅤ at Free against Calculator's $1.99. Calculator +ㅤ also leads on rating (4.6 vs 4.0) and update cadence (fortnightly vs every 11 months). Calculator's advantage is in-app purchases (none vs 6) and ads (none vs shown). On device support and iOS requirement there is nothing between them.

Calculator +ㅤ is free to download; Calculator costs $1.99 up front. Calculator +ㅤ sells 6 in-app purchases, starting at $2.99 per 7 days. Calculator asks for nothing beyond the download.

Calculator +ㅤ holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Calculator +ㅤ has 4.5K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 60% of Calculator's written reviews are positive against 46% of Calculator +ㅤ's, so the app with the better star average is not the one people write more warmly about.

Calculator ships an update every 11 months, Calculator +ㅤ fortnightly. The most recent releases landed on September 18, 2026 and September 23, 2026 respectively.
