Tide Now CR

Tide Now CR is a tide and currents calculator for the Columbia River, Willipa Bay, and Grays Harbor. It now supports current stations as well as tide stations. It displays tide/currents tables and graph. See example displays. See the region names, each one states either tide or currents in addition to the area. Self Contained - Offline OperationThis app does not use the internet to get its results. It performs its function purely by calculation. Quick Simple and CleanPredictions 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 (283 KB).User OptionsControls for the user are provided by three action bar icons and seven items in the settings menu. The action bar controls are Set Location, Set Date, and Refresh. The settings controls are Add Station to Favorites, GMap Station (internet), Change Color Scheme (Bright/Dark/ 3 others), Sun and Moon Info (3 levels available), Mark Height (lets you specify a height and the times are given on the display), About Gestures, and Overlay Waveform (lets you compare two different location graphs). Phone or TabletThe app works on any Android device at level 3.0.3 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 PredictionsThis 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 heights and tidal current tables. It uses the "Harmonic Prediction of Tides" methodology in long use for tide elevation predictions.Designed for On The Spot UseThe 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 black on white text choice is easily read on the bright sun.200 Year CalendarIn addition to todays 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.Tide Regions and Stations (note: "Tides" or "Currents for each grouping)Region Bar to Bridge TidesNorth JettyJetty A IlwacoChinookHammondWarrentonAstoria Port DocksAstoria Youngs BayCathcart LandingRegion Bar to Bridge CurrentsBaker Bay entrance, E of Sand Island TowerSand Island Tower, 0.9nm SE of (north channel)Sand Island Tower, 1nm SE of (midchannel) Clatsop Spit, NNE ofSand Island, SSE ofChinook Point, WSW ofPoint Adams, NNE OFMcGowan, SSW ofHammond, northeast of ship channelYoungs Bay BridgeRegion Bridge to Wauna TidesHungry HarborAstoria Tongue PointSettlers PointHarrington PointKnappaSkamokawaWaunaRegion Bridge to Longview CurrentsPoint Ellice, east ofTongue Point, northwest of Woody Island ChannelWoody Island Channel (off Seal Island)Quinn Island, Prairie ChannelClifton ChannelHunting Island, south ofCathlamet Channel, SE of Nassa PointWalker Island, south ofRegion Longview Upriver TidesLongviewKalamaSaint HelensRocky PointVancouverPortlandWashougalBeacon RockRegion Willipa BayNahcottaParadise PointBay CenterSouth Bend South Bend, Willipa River CurrentRaymond Toke PointRegion Grays Harbor TidesWestport Ocean Shores Point BrownBay CityMarkham AberdeenCosmopolis, Chehalis RiverMontesano, Chehalis RiverRegion Grays Harbor CurrentsGrays Harbor EntranceEntrance, 0.2 mile south of north jettyEntrance, Point Chehalis RangeEntrance, 1.1 miles NW of WestportEntrance, 0.6 mile WNW of WestportWestport, channel 0.4 mile NE ofChannel, 1.5 miles north of WestportChannel, 2.1 miles NNE of WestportMajor Update-Added Current Stations, added Grays Harbor, updated Tide Now Internals, checked with Android 10.
