Verdict
The clearest difference is rating: PolyTrak at 5.0 against Byki Mobile's 2.5. PolyTrak also leads on update cadence (every 5 days vs every 5 months). Byki Mobile's advantage is ratings volume (19 vs 1) and iOS requirement (12.0 vs 17.6). On price, ads, in-app purchases and monetization model there is nothing between them.
