Verdict
The clearest difference is rating: NozzleCalc at 5.0 against FARMserver's 4.5. NozzleCalc also leads on iOS requirement (11.0 vs 13.0). FARMserver's advantage is update cadence (every 2 months vs every 49 months) and ratings volume (14 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
