Verdict

The call

The clearest difference is review sentiment: Our engines at 100% against e's 31%. Our engines also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.0). e's advantage is rating (4.8 vs 4.5) and update cadence (every 2 months vs every 7 months). On price, ratings volume, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

e holds the better App Store score, 4.8 against 4.5. Both are backed by a comparable volume of ratings — 2 and 5 respectively. Written reviews complicate that: 100% of Our engines's written reviews are positive against 31% of e's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Our engines ships an update every 7 months, e every 2 months. Both last shipped on October 5, 2026.
