i purchased this app for my apple watch primarily because in the app store it shows that the watch will display a tide graph when using modular face. unfortunately this is not true. all that is displayed is name of location ,high tide, low tide, times etc. i know that $4 is not much at all, but money is money. i could have used the other 50 tide apps with 1k+ positive reviews for free, but chose this because of the way it claims to display the tide chart.
If the app has any problem they solve ASAP
Used the app for many years. Great technical support. Highly recommended.
Does not find cities in major areas like Alexandria or Norfolk in Virginia. Waste of money in my opinion.
