Tide Prediction works completely OFFLINE (except Google Maps integration) - meaning no costs for data traffic - and is ultra-fast.
The graphical tide chart also nicely indicates the daylight distribution. An event view shows the times for ebb and flood.
* tides for over 3000 tide and current stations world-wide (therefore, the app takes considerable space on your phone)
* uses your GPS and/or network provider to support location search
Please mail any issues and improvements. Thanks!
NOT FOR NAVIGATION. NO WARRANTY OF ANY KIND.
PLEASE NOTE: due to the underlying dataset, tide location coverage is limited to the following countries: USA, Canada, Mexico UK, Germany, Netherlands, South Africa, Japan, Australia, New Zealand
for all you boating people out there.
1. Navigation screen compass , GPS , time , speed knots
2. Weather screen shows nearest inland weather or shipping.
3. Add a way point screen
4. Tides nearest first,click for next 7 days.
Lots of tides mainly England,france,spain,portugal,
The app will get location from Cell or GPS and display closest
10 tides in distance order, also the weather is sorted with
closest location first.
You can select UK inshore or shipping forecast
from the menu feature.
Menu update-tides will down load the latest tides
and weather, when in new location always do a
update when you can.
The upgrade will allow you to make a small donation
to remove the adds.
Tides are GMT so add 1 hour for British summer time.
Always have another source of data to check with,
as data can be damaged during download.
All tide data is downloaded from www.ukho.gov.uk
with there permission.
No adds or dubious permission requirements, this is truly FREE.
Tide Guide calculates the Tides, Sun/Moon rise and set times, Lunar phases for any date.
Easily select any date past or future with the simple calendar widget.
Simply select from 2517 ports.
I am sorry but because of legal reasons many ports have been removed.
If anyone has legal, free access to harmonics for other ports I will gladly incorporate them into the program.
But if you live in a country where this is not available then talk to your countries tidal authority.
I have not done much in the way of Help.
However the way program works should be pretty obvious.
The program uses hot spots on the screen to move days viewed.
Check out the menu.
Initially there is an overlay to show the hot areas and what they do (this overlay can easily be turned off in the help menu).
The code is based on work I started in 1994. I began using the Admiralty Manual of Tides Australia and adapted various algorithms from Meus later I have incorporated some of the algorithms from XTide code (basically some code for calculating astronomical arguments). Unlike XTide and it's derivatives, the code calculates all astronomical positions on the fly.
It is difficult to know if this makes it more or less accurate as the original calculations for all port constituents have been based on Almanacs and speeds over a 12 month period. However tide prediction without incorporating atmospheric pressure levels specifically can only ever be a guide at best.
This program is not for navigation or to be used in any way where life or property is at risk.
I wrote this program primarily for myself.
If it is useful to you wonderful (then I also wrote this for you, and will help you improve your experience with it, if I can).
If the program is not useful just uninstall it it didn't cost you anything (I am not really interested in your negative opinions).
Provide query and analysis of real-time tidal data anywhere on the sea , also includes tide graph, phrases of the moon, fishing condition prediction and other feature
You can get real-time tide data at any time within the next year, and the historical data within a week before.
You can directly search for the location by entering coordinates, you can also search the location by map. And the apps can locate quickly in order to get the tidal data about the place where you are.
You can keep and manage your focusing places, and you can add notes to these places in order to facilitate the management.
Offer registration and login function, you can synchronize your favorites to another device.

Features a unique anchor projection system, just point and click and your anchor position is set. User defined swing area with exclusion and slack zones, runs in the background and can be controlled by SMS* from another phone.
Get SMS alerts* with embedded Google maps URLs, silent or audible alarms, with or without vibration, vessel tracking and more, all with very low memory use and long battery life.

If you want the best, you want Anchor Alert.
Anchor Alert is an advanced anchor alarm application made by a professional software developer and MCA certified Yachtmaster. It was the first anchor alarm available for Android devices and remains the number one choice of serious boaters. It uses a unique anchor projection algorithm which takes into account the magnetic declination of the current location to more accurately set the anchor point. It has a clutter-free interface and once initial verification has taken place runs fully off-line. It has been designed primarily to maximise reliability and battery life while allowing the user a great degree of flexibility and customisation.
See http://www.slimjimsoftware.co.uk for a full list of features.
** GPS accuracy and performance depends on your phone's hardware. Please read the help page fully and make sure you understand how to tell if this application is running in the background and how to completely stop it.
NOTE: some Android devices using versions 4.0 to 4.0.4 are known to be overly aggressive when shutting down background tasks, this interferes with Anchor Alert's background function and causes it to be shut down after a couple of hours without warning. if you own one of these affected devices please contact your carrier about an upgrade to 4.0.4 or later, in the meantime you should only use foreground mode. Android versions 2.x and 3.x should not be affected.
Finally, please email me and let me know how I can make this app better for you before leaving negative feedback. My goal is a 5 star rating from everyone that buys this app, please help me achieve this!
Please note: I have no control over data files so please try the free version first to see if the areas you want are included before buying this app.
Users in Canada should choose 'Non-Free' in the region dialogue, this also covers any non-free data for UK, Germany and Holland that may not be in the Europe region.
