# BT vs Car

The clearest difference is rating: Car at 1.6 against BT's 1.0. Car also leads on ratings volume (129 vs 5). BT's advantage is update cadence (every 3 months vs every 7 months) and review sentiment (20% vs 9%). 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.

Car holds the better App Store score, 1.6 against 1.0. That said, the two scores are not equally well evidenced: Car has 129 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 20% of BT's written reviews are positive against 9% of Car's, so the app with the better star average is not the one people write more warmly about.

BT ships an update every 3 months, Car every 7 months. The most recent releases landed on October 3, 2026 and October 23, 2026 respectively.
