Verdict
The clearest difference is review sentiment: Seismicity at 80% against EYDAPP's 36%. Seismicity also leads on rating (5.0 vs 2.5) and iOS requirement (11.0 vs 14.0). EYDAPP's advantage is update cadence (every 3 months vs every 7 months) and ratings volume (16 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.
