# SpeedBox App vs e

The clearest difference is rating: e at 5.0 against SpeedBox App's 3.6. SpeedBox App's advantage is update cadence (monthly vs every 3 months) and ratings volume (11 vs 1). On price, review sentiment, ads and in-app purchases there is nothing between them.

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

e holds the better App Store score, 5.0 against 3.6. That said, the two scores are not equally well evidenced: SpeedBox App has 11 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 20% of SpeedBox App's written reviews are positive against 17% of e's, so the app with the better star average is not the one people write more warmly about.

SpeedBox App ships an update monthly, e every 3 months. The most recent releases landed on September 21, 2026 and June 1, 2026 respectively.
