Love this app!

This may very well be the most useful app on my phone. I live in Pawleys Island and I love walking on the beach in the evenings looking for shark’s teeth and shells. I used to google search tidecharts and usually had to search quite awhile to find the information I was looking for. Even then, it was sometimes confusing and hard to read, as most of it was really geared towards fishermen who probably needed a lot more info than I did. With this app, I can pinpoint and save all of my favorite locations, see sunrise/sunset times, and just drag my finger across the screen to find the ideal times to head out. I’ve been using it for a few months now and it has been completely accurate every time- I literally use it every day.

Great but could be better

I am just an ordinary person, not a scientist, but I do have an interest in the tides. We live by the water and it’s cool to see when there’s a high-high or a low-low. It would be awesome to view this info in a chart like someone else suggested, because in the summer especially we love to go out into the Puget sound at a low-low because you can go really far out at Alki in Seattle. Makes for a fun family day. But I need the chart so I can view this info ahead of time to plan better. Would be great to also have with the sunrise/sunset.
Since we are watching the moon and it’s phases, an additional cool feature would be to show which stars/planets we would see on a particular night. There are many other stars apps to use tho. I really am interested in which planets I will see in the sky especially when they are close together (like recently there was Jupiter, Saturn, mars! All within the night sky, big and bright.
Thanks NOAA for amazing info tho on all of your sights/apps. My brother showed me MyRadar (he is a pilot and uses this info). I love the different layers on it.

This APP is all about my Shitzu Timkin.

He lives to put his paws in every
Low tide pool. We use this app daily weekly and monthly to plan ahead. I wish the weather was as easy to predict, but who can tame wild. Here on the Pacific Ocean no water is too cold for Timkin to plunge into. Keep you dogs young take them wild tide pool swimming. Using this cool app And the added benefit is tides are caused by the moon so the moons phases are depicted in a wonderful way. Can I share it by sending it in email? I hope so. Thankyou for this great app. Now if I could find a real-time app for the weather specifically for where I live. Last week the fog gave us more precipitation than the predicted storm. Love this app.
