Verdict
The clearest difference is in-app purchases: Decision Tool at none against CarQR App's 4. Decision Tool also leads on iOS requirement (13.0 vs 15.0). CarQR App's advantage is ads (none vs shown) and update cadence (every 2 days vs fortnightly). On price and device support there is nothing between them.
