# Tide Charts vs Swift Warning

The clearest difference is update cadence: Swift Warning at every 2 days against Tide Charts's every 3 weeks. Swift Warning also leads on rating (5.0 vs 4.8). Tide Charts's advantage is ratings volume (114K vs 1) and chart position (#24 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.
