# Car Matrix vs QDI

The clearest difference is rating: Car Matrix at 3.3 against QDI's 3.0. Car Matrix also leads on iOS requirement (9.0 vs 17.0). QDI's advantage is review sentiment (23% vs 9%) and ratings volume (56 vs 18). On price, update cadence, 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.

Car Matrix holds the better App Store score, 3.3 against 3.0. Both are backed by a comparable volume of ratings — 18 and 56 respectively. Written reviews complicate that: 9% of Car Matrix's written reviews are positive against 23% of QDI's, so the app with the better star average is not the one people write more warmly about.
