The clearest difference is update cadence: Calvis at weekly against Nation Link Plus's every 11 months. Calvis also leads on ratings volume (13 vs 1). Nation Link Plus's advantage is rating (5.0 vs 4.7) and iOS requirement (15.6 vs 17.2). On price, ads, in-app purchases and monetization model there is nothing between them.
