Verdict

The call

The clearest difference is in-app purchases: Ultra Boost at none against OBD JScan's 8. Ultra Boost also leads on rating (5.0 vs 4.7) and review sentiment (100% vs 80%). OBD JScan's advantage is ratings volume (1.3K vs 4) and update cadence (every 3 weeks vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.
