Verdict
The clearest difference is in-app purchases: Auto101 Pro at none against OBD JScan's 8. Auto101 Pro also leads on review sentiment (100% vs 80%) and rating (5.0 vs 4.7). OBD JScan's advantage is ratings volume (1.3K vs 5) and iOS requirement (13.0 vs 16.0). On price, update cadence, ads and device support there is nothing between them.
