Verdict

The call

The clearest difference is review sentiment: Coverage Map at 68% against aeris's 2%. Coverage Map also leads on rating (4.7 vs 1.3) and update cadence (fortnightly vs monthly). aeris's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases and device support there is nothing between them.
