What people are saying about Anchor Alert...
What is Anchor Alert? Anchor Alert is an advanced anchor alarm application from SlimJiM Software developed exclusively for Android. Anchor Alert was the first anchor alarm available for Android and still leads the rest in terms of features and reliability. It features point and click anchor projection using the phone's built-in GPS and compass and allows setting of an exclusion area and optional slack zone. Together with the audible and haptic (vibration) alerts and support for running as a background task which allows the phone's GPS to sleep to save power, Anchor Alert is the world's most advanced smart-phone based anchor alarm. Anchor Alert is only available on the Google Play store. Read on to learn about some of the advanced features of this application and some of the other uses it can be put to... Please note: Due to the use of some advanced functions only available in newer releases of Android, Anchor Alert is not
available for versions earlier than 4.0. If you are stuck on an older version of Android and wish to use Anchor Alert you should contact your
carrier about an upgrade. Main Features of Anchor Alert:Projecting the Anchor Position.Unlike other anchor alarms, Anchor Alert allows you to project an anchor position in any direction and by any distance you want by simple point and click. Anchor Alert uses Android's magnetic declination tables to automatically correct the phone's built-in compass for local magnetic differences so that an accurate anchor position can be calculated at any time and at any position on the globe. These magnetic declination tables are updated as required with the Android system so they will always remain as up to date as your phone. Exclusion Angle and Slack Zone.Anchor Alert allows any sector of the anchor circle to be excluded from the allowed swing area and if your vessel drifts into it, an alarm will be triggered. This may be useful when you find the need to anchor your vessel close to land for more protection, close to another vessel that is moored to a buoy, or when anchored in a steady wind and you want to know when the wind changes. The exclusion area can be input with precision from the application preferences or with ease by touch and drag accessible by long-pressing on the centre of the screen. You may also find at times that you wish to define a slack zone within the exclusion area. For example, when anchored in a bay where the vessel might swing around 180 degrees from it's original position due to tidal changes but you may only wish to be alerted if the anchor is likely to drag and not when the vessel has just wandered over the anchor position at slack tide. Anchor Alert allows this too. By setting the Slack Zone option and independently changing both the distance to anchor and the drift distance, any size slack area may be set around the anchor position. Advanced Features:Night ModeAnchor Alert also has a night mode that dims the screen and changes the colour scheme so you don't lose your night vision. Background MonitoringAnchor Alert is designed to take full advantage of Android's multi-tasking ability. It is capable of monitoring the anchor position while running as a background task and allows you to use your device for other things such as checking your email or taking a call. No other smart-phone based anchor alarm can do that! Metric or ImperialPrefer to use feet? Or do you work better with the metric system? No problem. Anchor Alert supports both metric and imperial measurements, just select your preference from the menu and it's all taken care of. Multiple Alarm OptionsAnchor Alert supports audio and vibration alert options and a visible alert dialog is also displayed through which you can cancel or snooze the alarm for a period that you define. Low Battery WarningAnchor Alert can also inform you if your battery is getting low. By selecting the low battery alert in the application settings a visual notification with optional audio and vibration alerts will be triggered to alert you that the battery is running down. Once at 15% power, then again at 10% and at every change from 5% and below. Security and PrivacyAnchor Alert takes your security and privacy seriously too, the location data used in historic traces is relative to the anchor point only and no personal data whatsoever is collected or stored. Other Uses of Anchor Alert:Take Me To...Set the exclusion area start position to 190 degrees and set the scope to 340, set the anchor position to however far away your target is, say 30,000 metres (30kM) or 100,000 feet (19 miles), from your current position, point the phone in the direction you wish to travel and press OK to set anchor. You can then use Anchor Alert as a guide to your location, stray too far off course and you'll get an alert, the alert area also gets smaller the closer you get to your desired location (the anchor position) so you need never be too far off course. Make sure anchor tracking is enabled too and let Anchor Alert guide you both magnetically and by your phone's GPS. Dude, where's my boat? - (Remembering a Location)
