Verdict

The call

The clearest difference is review sentiment: GeoQuake at 100% against Japan Alerts's 20%. GeoQuake also leads on ads (none vs shown) and iOS requirement (12 vs 15.1). Japan Alerts's advantage is update cadence (weekly vs every 2 months). On price, in-app purchases, monetization model and device support there is nothing between them.
