I've used Navionics for tides all over the world. It's great because I don't have to open another app for tide OR wind
information. It's all right there overlaid on your chart.
To access tides and/or wind
just click on menu at the bottom, click Weather
and tides when the menu pops up.
then you'll see a box with 4 quadrants pop up. (YOu can set the location of that by clicking "edit" in the upper right corner... you can add multiple locations for easy access.)
Then click on the bottom left quadrant where tide information is and you'll see tide information graph on the bottom of the screen
. You can scroll through it and get detailed info by clicking Details in the bottom left.
If you want to do a wind overlay just click on the top right quadrant where you see the wind vector.
