Verdict
The clearest difference is ads: AlphaCast at none against Tide Charts's shown. AlphaCast also leads on review sentiment (100% vs 69%) and rating (5.0 vs 4.8). Tide Charts's advantage is ratings volume (115K vs 11) and chart position (#34 vs unranked). On price, in-app purchases and monetization model there is nothing between them.
