And (2) Today, I received an interstitial ad with uninitiated audio, which means that music started to play for an ad as I open the app without any ability to control to stop it for a period of time. The survey itself was strongly biased toward one particular point of view, and wasn’t really a scientific survey or poll intended to get true public sentiment, so I found it annoying to go through, knowing the results would not be used fairly. Two recent examples come to mind: (1) I received a survey invitation in the app to weigh in on building the wall between the US and Mexico. I don’t really mind ads in general, as I know they need to make money, but the way they are implementing advertising on this app results in an unacceptable use experience. This was a very simple and useful app for a long time until recently, when I started to receive a lot of annoying and unprofessional advertising on it. I used to like this app until it got spammy
#Tide tables free
When I am not working and have free time, I probably use my tide app about four times or more and that is nearly everyday. I still use my paper tide calendar to see future tides more than a week or two out, yet if need be, I can scroll over to see future tides on the app as well. This helps me plan my walks and swims so I do not get clobbered with waves crashing against cliffs or rocks while walking, and can float over rocks while swimming, and to plan for sunlight or starlight. I love how clear the graph is, showing me how the tide will be rising and falling throughout the day and night, and clearly showing me sunrise and sunset as well. I love that it tells me the exact feet and inches at the moment with a little arrow pointing up or down for rising or falling tide. This app is more useful than my paper tide calendar for daily use. Before the use of digital computers tide tables were often generated by the use of a special-purpose calculating machine, the tide-predicting machine.I use this app to plan my 8-mile beach walks and to plan when I will swim in the ocean. Tide prediction was long beset by the problem of laborious calculations.
#Tide tables full
On the Atlantic coast of northwest Europe, the interval between each low and high tide averages about 6 hours and 10 minutes, giving two high tides and two low tides each day, with the highest tides about 2 days after full moon. However, successive (semidiurnal) tides are linked to the Moon's orbital period, thus they are approximately 24/27.3 hours later each day or about 50 minutes but many other observations and considerations are required to develop accurate tide tables. This cycle of tides is linked to the phases of the moon, with the highest tides (spring tides) occurring near full moon and new moon. The dates of spring tides and neap tides, approximately seven days apart, can be determined by the heights of the tides on the classic tide tables: a small range indicates neaps and large indicates springs.
The tide times for a minor port are estimated by the tide-table user manually calculating using the published time and height differences between a standard port and the minor port. Most tide tables are calculated and published only for major ports, called "standard ports", and only for one year - standard ports can be relatively close together or hundreds of kilometers apart. Tide tables are published in various forms, such as paper-based tables and tables available on the Internet.
