The clearest difference is review sentiment: Carmin at 55% against AnaHertz's 0%. Carmin also leads on rating (4.3 vs 3.3) and ratings volume (234 vs 7). AnaHertz's advantage is ads (none vs shown) and iOS requirement (10.2 vs 12). On price, update cadence, in-app purchases and monetization model there is nothing between them.
