Verdict
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).

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
