This Android application calculates and presents the tide
for a given day, time, and location.
It does not require internet service, because it operates
with built-in formulas and data.
It first shows the location for which the tide is being
calculated. It displays the day of the week and the date and time zone for which the tides shown below are calculated.
Next it displays the present tidal status. This is a
snapshot in time, including the present height of the tide,
the direction is it flowing, and how fast the tide
level is changing. These items are presented along with the time for which they were calculated.
It then displays the times and times of the tidal extremes, the high tides and low tides. There are usually three or four highs and lows in a day.
Finally it displays a plot of the tide heights for the day.
The green dots are the hourly heights. The white cursor-
line marks the present time. The red dots show the high and
low tides. A quick glance shows you what you need to know.
This graph is presented on a fixed 2 foot and 2 hour grid.
You can change the text size to trade off display space
between the graph and the tables above it.
Tide Now supports three touch-screen gestures. The display
can be changed to the next day or the previous day by swiping left or right. The display can be refreshed by using a long press. This causes an updated display to be presented.
Tide Now has no advertising and does not access phone
features except the touch screen.
