# Dauntless OBD vs OBD Quest

The clearest difference is in-app purchases: Dauntless OBD at none against OBD Quest's 3. Dauntless OBD also leads on ads (none vs shown) and ratings volume (11 vs 1). On price, rating, update cadence and device support there is nothing between them.

Both are free to download. OBD Quest sells 3 in-app purchases, starting at $9.99 per month. Dauntless OBD asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Dauntless OBD against 5.0 for OBD Quest. That said, the two scores are not equally well evidenced: Dauntless OBD has 11 ratings behind it against 1, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on October 13, 2026 and October 2, 2026 respectively.
