Verdict

The call

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.
