Verdict
The clearest difference is rating: CASpire at 5.0 against Konstella's 4.6. CASpire also leads on device support (3 vs 1) and iOS requirement (13.0 vs 18.0). Konstella's advantage is update cadence (every 3 days vs every 3 weeks) and ratings volume (1.2K vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
