# Carista OBD2 vs BWT RC

The clearest difference is rating: Carista OBD2 at 4.6 against BWT RC's 3.0. Carista OBD2 also leads on ratings volume (4.3K vs 2) and chart position (#189 vs unranked). BWT RC's advantage is in-app purchases (none vs 14) and ads (none vs shown). On price, review sentiment and device support there is nothing between them.

Both are free to download. Carista OBD2 sells 6 in-app purchases, starting at $19.99 per month. BWT RC asks for nothing beyond the download.
