Verdict
The clearest difference is in-app purchases: Fabrication Helper at none against OBD Scan Pro's 1. Fabrication Helper also leads on ads (none vs shown) and iOS requirement (15.0 vs 17.6). OBD Scan Pro's advantage is update cadence (every 2 weeks vs every 2 months). On price and device support there is nothing between them.
