# Ultra Boost vs OBD2 Scanner

The clearest difference is review sentiment: Ultra Boost at 100% against OBD2 Scanner's 23%. Ultra Boost also leads on in-app purchases (none vs 6) and ads (none vs shown). OBD2 Scanner's advantage is ratings volume (1.1K vs 4) and update cadence (monthly vs every 2 months). On price and device support there is nothing between them.

Both are free to download. OBD2 Scanner sells 6 in-app purchases, starting at $6.99 per 7 days. Ultra Boost asks for nothing beyond the download.

Ultra Boost holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: OBD2 Scanner has 1.1K ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 100% of Ultra Boost's written reviews are positive against 23% of OBD2 Scanner's.
