# E vs Toolbox TREMEC U.S.

The clearest difference is review sentiment: Toolbox TREMEC U.S. at 100% against E's 46%. Toolbox TREMEC U.S. also leads on iOS requirement (13.0 vs 16.0). E's advantage is rating (3.9 vs 3.3) and ratings volume (24 vs 3). On price, ads, in-app purchases and monetization model 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, 3.9 against 3.3. That said, the two scores are not equally well evidenced: E has 24 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 46% of E's written reviews are positive against 100% of Toolbox TREMEC U.S.'s, so the app with the better star average is not the one people write more warmly about.
