Verdict

The call

The clearest difference is ads: PredictWind at none against Tide Charts's shown. PredictWind also leads on review sentiment (84% vs 69%) and update cadence (every 9 days vs every 3 weeks). Tide Charts's advantage is device support (4 vs 2) and ratings volume (115K vs 33K). On price, rating, in-app purchases and monetization model there is nothing between them.
