# Calculator+ vs Calculator 17

The clearest difference is review sentiment: Calculator+ at 100% against Calculator 17's 22%. Calculator+ also leads on iOS requirement (13.0 vs 16.0). Calculator 17's advantage is rating (4.6 vs 4.0) and update cadence (every 4 days vs every 5 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Calculator 17 holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Calculator 17 has 971 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Calculator+'s written reviews are positive against 22% of Calculator 17's, so the app with the better star average is not the one people write more warmly about.

Calculator+ ships an update every 5 months, Calculator 17 every 4 days. The most recent releases landed on August 11, 2026 and September 17, 2026 respectively.
