# Calculator₊ vs The Simple Calculator

The clearest difference is ratings volume: Calculator₊ at 1.7M against The Simple Calculator's 171. Calculator₊ also leads on chart position (#92 vs unranked) and device support (5 vs 3). The Simple Calculator's advantage is review sentiment (77% vs 63%) and update cadence (weekly vs fortnightly). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Calculator₊ sells 12 in-app purchases, starting at $0.99 per month and The Simple Calculator sells 1 one-off in-app purchase. 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 The Simple Calculator. That said, the two scores are not equally well evidenced: Calculator₊ has 1.7M ratings behind it against 171, 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 77% of The Simple Calculator's.

Calculator₊ ships an update fortnightly, The Simple Calculator weekly. The most recent releases landed on September 24, 2026 and September 12, 2026 respectively.
