Verdict
The clearest difference is in-app purchases: Duostories at none against Kalam's 18. Duostories also leads on rating (5.0 vs 4.7). Kalam's advantage is ratings volume (6.8K vs 1) and chart position (#128 vs unranked). On price, update cadence, ads and device support there is nothing between them.
