Ratings and reviews

This has been very helpful., I've used this for years sailing between islands. Much easier using this than the current charts and trying to figure out what it will be like at the time of crossing. Made great time going to and from Sucia from Anacortes. Would love to see more detail to determine best paths for where current is strongest other than guessing in the center.

makes planning trips through the San Juans so much easier. the Canadian current charts (that this app is based on) are invaluable but cumbersome to use. this is top value!

Exceptional and Simple. The app does exactly what it's supposed to - and that isn't much. What it is supposed to do though, providing tide charts for the Salish Sea, it does perfectly. While it's rudimentary, it doesn't need to be anything more than what it currently is. The only point I can comment on is that I am excited to see more areas available, considering the cost, and maybe the ability to see tide times at specific locations. Perfect for quickly planning kayaking and sailing.
