Verdict

The call

The clearest difference is review sentiment: Seismicity at 80% against Nova's 30%. Seismicity also leads on rating (5.0 vs 4.6) and monetization model (free vs ad-supported). Nova's advantage is update cadence (fortnightly vs every 7 months) and ratings volume (404 vs 2). On price, ads, in-app purchases and device support there is nothing between them.
