Verdict

The call

The clearest difference is review sentiment: D at 100% against OBDeleven's 14%. D also leads on rating (5.0 vs 4.3) and in-app purchases (none vs 13). OBDeleven's advantage is ratings volume (1.6K vs 5) and update cadence (fortnightly vs monthly). On price, ads and device support there is nothing between them.
