Verdict

The call

The clearest difference is update cadence: Kulmo at every 3 days against Rost's every 24 months. Kulmo also leads on ratings volume (19 vs 1). Rost's advantage is monetization model (free vs freemium) and review sentiment (100% vs 80%). On price, rating, ads and in-app purchases there is nothing between them.
