Verdict

The call

The clearest difference is ads: Light Matter Kit at none against Coverage Map's shown. Light Matter Kit also leads on iOS requirement (12.0 vs 15.0). Coverage Map's advantage is update cadence (fortnightly vs every 9 months). On price, in-app purchases and device support there is nothing between them.
