Verdict
The clearest difference is rating: NozzleCalc at 5.0 against ShurLink's 3.9. NozzleCalc also leads on iOS requirement (11.0 vs 15.0). ShurLink's advantage is update cadence (every 4 months vs every 49 months) and ratings volume (7 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
