Verdict

The call

The clearest difference is ads: Going Blue at none against Mountain's shown. Going Blue also leads on update cadence (every 8 days vs every 2 months) and monetization model (free vs free with in-app purchases). Mountain's advantage is ratings volume (845 vs 4) and chart position (#60 vs unranked). On price, rating, in-app purchases and iOS requirement there is nothing between them.
