Great AP for Great Lakes Sailors

This is very cool. Give a great summary relevant to boaters by touching your location in the screen. You can see wave height for the bouts near you. When I wasn’t sure what wave period was I emailed a question and Will wrote me back within a few minutes with a detailed article from surfology. Buy it, definitely a good AP, especially for the money.

Excellent and reliable weather and buoy reports

I like this app for four main reasons:
1. The text forecast is concise, simple, and accurate. It tells me wind, temperature, and general conditions.
2. NWS alerts are posted every time the app launches.
3. The buoy data provides near-real-time sea conditions. This let’s me know ahead of time if I should venture outside of the Buffalo, NY breakwater.
4. The discussion tab gives great and accurate insight into forces causing weather conditions over the next 72-96 hours.

This is the best weather app I have used so far. I rely on it daily during the summer.

Updated review

I reviewed this app when it was brand new and didn’t have anything that wasn’t available on other apps. It just keeps adding features and now I use only this and Windy. Great job with the updates!
