# Essential Calculator vs Simple Calculator.

The clearest difference is rating: Simple Calculator. at 4.6 against Essential Calculator's 4.0. Simple Calculator. also leads on ratings volume (1.6K vs 8). Essential Calculator's advantage is ads (none vs shown) and monetization model (free vs ad-supported). On price, update cadence, in-app purchases and device support there is nothing between them.

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

Simple Calculator. holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: Simple Calculator. has 1.6K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 75% of Essential Calculator's written reviews are positive against 65% of Simple Calculator.'s, so the app with the better star average is not the one people write more warmly about.

Essential Calculator ships an update every 4 months, Simple Calculator. every 3 months. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
