# NVH vs Toolbox TREMEC U.S.

The clearest difference is price: Toolbox TREMEC U.S. at Free against NVH's $99.99. Toolbox TREMEC U.S. also leads on review sentiment (100% vs 81%) and iOS requirement (13.0 vs 17.0). NVH's advantage is rating (4.2 vs 3.3) and chart position (#196 vs unranked). On ads, in-app purchases and device support there is nothing between them.

Toolbox TREMEC U.S. is free to download; NVH costs $99.99 up front. Neither carries in-app purchases, so what you see is what you pay.

NVH holds the better App Store score, 4.2 against 3.3. That said, the two scores are not equally well evidenced: NVH has 24 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 81% of NVH'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.
