# TopGuru vs OBD2 Car Scanner

The clearest difference is ads: TopGuru at none against OBD2 Car Scanner's shown. TopGuru also leads on review sentiment (29% vs 4%) and update cadence (every 3 weeks vs every 2 months). OBD2 Car Scanner's advantage is rating (3.8 vs 3.5) and ratings volume (1.5K vs 413). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. TopGuru sells 9 in-app purchases, starting at $9.99 per month and OBD2 Car Scanner sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

OBD2 Car Scanner holds the better App Store score, 3.8 against 3.5. Both are backed by a comparable volume of ratings — 413 and 1.5K respectively. Written reviews complicate that: 29% of TopGuru's written reviews are positive against 4% of OBD2 Car Scanner's, so the app with the better star average is not the one people write more warmly about.

TopGuru ships an update every 3 weeks, OBD2 Car Scanner every 2 months. The most recent releases landed on November 3, 2026 and November 4, 2026 respectively.
