Finally a beautiful and simple way to view tides on your mobile device! In addition to worldwide tidal estimates at tide stations, you can see the lunar data, weather forecast, and current radar making your next outdoor adventure as easy to plan as possible. By default, the application will pick the closest tide station to you, but picking a different tide or weather station is as easy as viewing a map of your current location. You can also setup and quickly switch between many stored favorite stations if you need to. No internet access while outdoors? No problem. This app has been designed to give you tidal and lunar predictions without internet access!

Verdict
The clearest difference is in-app purchases: SargView at none against Tide Charts's 1. SargView also leads on ads (none vs shown) and iOS requirement (13.4 vs 15.1). Tide Charts's advantage is update cadence (every 3 weeks vs every 15 months) and chart position (#33 vs unranked). On price there is nothing between them.
