Verdict
The clearest difference is update cadence: KTuner FlexFuel at daily against POWERlink Suite's every 2 weeks. KTuner FlexFuel also leads on rating (5.0 vs 4.8) and iOS requirement (11.0 vs 17.0). POWERlink Suite's advantage is ratings volume (1.7K vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
