Features of Tide Now App

Self Contained This app does not use the internet to get its results. It performs its function purely by calculation. It will work on a phone or a tablet in or out of range of communications.
Quick Simple and Clean Predictions are quick and the app is simple to use and understand. Gestures are supported for looking at the next and prior day tides. There are no ads and app cannot access phone features. The app is small, under 200 KB.
Simple User Options There are controls for the user, provided by the settings menu, to set it up as desired.
Phone or Tablet The app works on any Android device at level 2.3.3 or above, most phones and tablets are supported. Depending on the nature of your android device, the landscape or portrait mode display may present a more useful size.
Accurate Predictions This app was written using well-known tidal prediction algorithms and publicly available location data. It can be expected to match very closely to federally-published tide tables. It uses the "Harmonic Prediction of Tides" methodology in long use for tide elevation predictions.
Designed for On The Spot Use The tidal status presentation gives an immediate snapshot of the tide situation, more useful than just a standard list of highs and lows. The display can be refreshed at any time to update this status. This app is designed for use while actively out and about along the waterfront. It uses large text and the white on black text choice is easily read on the bright sun.

200 Year Calendar

In addition to today's tides, a date picker is available to choose any date from 1901 to 2100. The app does not have to be refreshed on the new year.
Next Day, Prior Day Swipes Gestures are supported to go to "next day" and "past day" to step day by day through a range of dates. These operate like turning the page of a book. You can quickly swipe through a range of dates to look for good clam digging days.
Favorites The selected station can be added to a set of eight favorites. These can be accessed by a down-swipe.
Adjustable Colors There are five color schemes, good for situations ranging from bright sun to night use. Try each one out depending in which conditions you use the app you can find one that works best.
Numerous Tide Stations There are locations available around the inland waterway as well as the coastal areas.


Disclaimer/Scope of Tide Now App

The application is built for either Washington, Oregon, or California. There are three apps, Tide Now WA, Tide Now OR, and Tide Now CA.

The tide predictions, being made on the client's phone or tablet, are impossible to guarantee as correct.

Each display contains a station number on the upper right corner of the graph. This number can be used to refer to the NOAA tide tables for that station if there is any concern. Please contact me with any concern, question, or suggestion; I actively support these apps with email or phone as necessary.


Set Up Options (Settings Menu)

NEW NOTE: Galaxy S5 users. See http://www.androidcentral.com/samsung-galaxy-s5-menu-button-hidden.

The set up menu is accessed in one of two ways depending on your phone. On older generation Android devices, there is a dedicated button used for a settings key.
In newer designs, there is the menu symbol on the screen display, in the soft buttons area. This type is shown above, it is the three dots or dashes..

In either case, choosing the options menu and settings follows the same procedure. Display above shows what is seen when the settings button is used.

The table below describes the six settings items.


Show Now, Today For use when you have been looking at other dates, it brings the tide display back to today/now. Note: The "long press" gesture can be used for this purpose also.
Pick Date A calendar entry dialog is displayed, you can choose a month day and year, for which that day's tides will then be displayed. Note: Dates other than "today" will have the highs and lows and the hourly heights displayed, but will not have the tidal status display. The tidal status display is not possible for this situation because there is no particular time to reference. Note: you can pick any year between 1901 and 2100.
Select Region and Station Depending on the state, there are a variety of numbers of tide stations available. These are organized by regions.
First you pick the region then the place within that region, called the "tide station". There are eighty stations in Washington, forty in Oregon, and about 150 in California.
Add Station to Favorites There is a favorites menu, and you can add place the presently selected station into any of the eight favorites.
Change Text Color There are five color schemes available, for various situations. See display below.
About Gestures The four gestures supported are listed, and each can also be directly activated by using the menu item.
