# Calculator # vs Calculator M+

The clearest difference is ads: Calculator M+ at none against Calculator #'s shown. Calculator M+ also leads on update cadence (fortnightly vs every 2 months). Calculator #'s advantage is ratings volume (36K vs 110). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. Calculator # sells 6 in-app purchases, starting at $1.49 per month and Calculator M+ sells 1 in-app purchase, starting at $6.99 per year. 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 4.5 for Calculator M+. That said, the two scores are not equally well evidenced: Calculator # has 36K ratings behind it against 110, so its average is the more settled of the two. Written reviews are what separate them: 60% of Calculator #'s written reviews are positive against 64% of Calculator M+'s.

Calculator # ships an update every 2 months, Calculator M+ fortnightly. The most recent releases landed on September 29, 2026 and September 22, 2026 respectively.
