# Simple Calculator. vs T

The clearest difference is ads: T at none against Simple Calculator.'s shown. T also leads on update cadence (weekly vs every 3 months) and rating (5.0 vs 4.6). Simple Calculator.'s advantage is ratings volume (1.6K vs 2) and review sentiment (65% vs 43%). On price, in-app purchases, device support and iOS requirement there is nothing between them.

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

T holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Simple Calculator. has 1.6K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 65% of Simple Calculator.'s written reviews are positive against 43% of T's, so the app with the better star average is not the one people write more warmly about.

Simple Calculator. ships an update every 3 months, T weekly. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
