# Calculator⁼ vs Calculator +ㅤ

The clearest difference is monetization model: Calculator⁼ at free with in-app purchases against Calculator +ㅤ's subscription. Calculator⁼ also leads on ratings volume (358K vs 4.5K). Calculator +ㅤ's advantage is update cadence (fortnightly vs monthly) and review sentiment (46% vs 36%). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Calculator⁼ sells 8 in-app purchases, starting at $0.49 per 7 days and Calculator +ㅤ sells 6 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for Calculator⁼ against 4.6 for Calculator +ㅤ. That said, the two scores are not equally well evidenced: Calculator⁼ has 358K ratings behind it against 4.5K, so its average is the more settled of the two. Written reviews are what separate them: 36% of Calculator⁼'s written reviews are positive against 46% of Calculator +ㅤ's.

Calculator⁼ ships an update monthly, Calculator +ㅤ fortnightly. The most recent releases landed on September 25, 2026 and September 23, 2026 respectively.
