# e vs MultiiCalc

The clearest difference is rating: MultiiCalc at 5.0 against e's 3.0. MultiiCalc also leads on update cadence (monthly vs every 5 months) and ratings volume (9 vs 1). e's advantage is in-app purchases (none vs 3) and iOS requirement (6.1 vs 14.0). On price, review sentiment, ads and device support there is nothing between them.

Both are free to download. MultiiCalc sells 3 one-off in-app purchases. e asks for nothing beyond the download.

MultiiCalc holds the better App Store score, 5.0 against 3.0. That said, the two scores are not equally well evidenced: MultiiCalc has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 56% of e's written reviews are positive against 50% of MultiiCalc's, so the app with the better star average is not the one people write more warmly about.

e ships an update every 5 months, MultiiCalc monthly. The most recent releases landed on October 5, 2026 and October 3, 2026 respectively.
