Verdict

The call

The clearest difference is review sentiment: C at 51% against EarthScope's 5%. C also leads on rating (4.5 vs 3.8) and ads (none vs shown). EarthScope's advantage is in-app purchases (none vs 11) and update cadence (fortnightly vs every 6 weeks). On price, device support and iOS requirement there is nothing between them.
