Verdict

The call

The clearest difference is rating: Luwi at 5.0 against Byki Mobile's 2.5. Luwi also leads on update cadence (every 10 days vs every 5 months) and monetization model (free vs free with in-app purchases). Byki Mobile's advantage is ratings volume (19 vs 3) and iOS requirement (12.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
