# 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 (1.7M vs 4.5K) and review sentiment (63% vs 46%). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Calculator₊ sells 12 in-app purchases, starting at $0.99 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 — 4.7 for Calculator₊ against 4.6 for Calculator +ㅤ. That said, the two scores are not equally well evidenced: Calculator₊ has 1.7M ratings behind it against 4.5K, so its average is the more settled of the two. Written reviews are what separate them: 63% of Calculator₊'s written reviews are positive against 46% of Calculator +ㅤ's.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on September 25, 2026 and September 23, 2026 respectively.
