Verdict
The clearest difference is monetization model: xade roast at freemium against Nelko's subscription. Nelko's advantage is ratings volume (21K vs 1) and chart position (#152 vs unranked). On price, rating, update cadence and ads there is nothing between them.

On the App Store both sit at effectively the same score — 5.0 for xade roast against 4.9 for Nelko. That said, the two scores are not equally well evidenced: Nelko has 21K ratings behind it against 1, so its average is the more settled of the two.
