# Scientific Calculator vs DataCentral

The clearest difference is update cadence: DataCentral at every 3 days against Scientific Calculator's monthly. DataCentral also leads on rating (5.0 vs 4.8) and review sentiment (100% vs 89%). Scientific Calculator's advantage is ratings volume (17 vs 2) and iOS requirement (13.0 vs 17.6). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Scientific Calculator sells 4 in-app purchases, starting at $0.99 per month and DataCentral sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

DataCentral holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Scientific Calculator has 17 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 89% of Scientific Calculator's written reviews are positive against 100% of DataCentral's.

Scientific Calculator ships an update monthly, DataCentral every 3 days. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
