Verdict
The clearest difference is rating: PhosFilter at 4.4 against Kidney Diet Tracker's 1.5. PhosFilter also leads on review sentiment (36% vs 0%) and ratings volume (172 vs 2). Kidney Diet Tracker's advantage is update cadence (every 3 days vs every 6 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.
