Verdict
The clearest difference is rating: BlueDriver OBD2 Scan Tool at 4.6 against Walabot DIY's 4.2. BlueDriver OBD2 Scan Tool also leads on ratings volume (14K vs 320). Walabot DIY's advantage is monetization model (free vs free with in-app purchases) and review sentiment (78% vs 57%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
BlueDriver OBD2 Scan Tool holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: BlueDriver OBD2 Scan Tool has 14K ratings behind it against 320, so its average is the more settled of the two. Written reviews complicate that: 57% of BlueDriver OBD2 Scan Tool's written reviews are positive against 78% of Walabot DIY's, so the app with the better star average is not the one people write more warmly about.
BlueDriver OBD2 Scan Tool ships an update fortnightly, Walabot DIY every 3 weeks. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
