Verdict
The clearest difference is rating: EarthWatch at 5.0 against CIRSS's 1.8. EarthWatch also leads on update cadence (every 2 weeks vs every 4 months). CIRSS's advantage is ratings volume (5 vs 1) and iOS requirement (12.0 vs 26.2). On price, ads, in-app purchases and device support there is nothing between them.
