# Calculator vs Calculator +ㅤ

The clearest difference is monetization model: Calculator at freemium against Calculator +ㅤ's subscription. Calculator also leads on review sentiment (80% vs 46%). Calculator +ㅤ's advantage is update cadence (fortnightly vs every 2 months) and ratings volume (4.5K vs 200). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Calculator sells 4 in-app purchases, starting at $2.49 per month 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 +ㅤ has 4.5K ratings behind it against 200, so its average is the more settled of the two. Written reviews are what separate them: 80% of Calculator's written reviews are positive against 46% of Calculator +ㅤ's.

Calculator ships an update every 2 months, Calculator +ㅤ fortnightly. The most recent releases landed on September 14, 2026 and September 23, 2026 respectively.
