# OBD2 Scanner vs CodigosDTC

The clearest difference is ads: CodigosDTC at none against OBD2 Scanner's shown. CodigosDTC also leads on rating (5.0 vs 4.6) and update cadence (every 2 days vs monthly). OBD2 Scanner's advantage is ratings volume (1.1K vs 2). On price, in-app purchases, monetization model 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 and CodigosDTC sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

CodigosDTC 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 2, so its average is the more settled of the two.

OBD2 Scanner ships an update monthly, CodigosDTC every 2 days. The most recent releases landed on November 8, 2026 and October 31, 2026 respectively.
