# Calculator + vs Calculator Smart

Calculator + and Calculator Smart both sit at 4.6 stars, but that hides the real split: 85% of Calculator +'s written reviews are positive against 36% of Calculator Smart's. Calculator + also leads on update cadence (every 4 days vs every 4 months) and ratings volume (10K vs 494). Calculator Smart's advantage is device support (6 vs 2) and iOS requirement (13.0 vs 16.4). 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 $4.99 per month and Calculator Smart sells 3 one-off in-app purchases. 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 4.7 for Calculator Smart. That said, the two scores are not equally well evidenced: Calculator + has 10K ratings behind it against 494, so its average is the more settled of the two. Written reviews are what separate them: 85% of Calculator +'s written reviews are positive against 36% of Calculator Smart's.

Calculator + ships an update every 4 days, Calculator Smart every 4 months. The most recent releases landed on September 24, 2026 and September 12, 2026 respectively.
