Mad Mutt Marine Navigator 2

The original Mutt navigator has been dragged by the tail into the modern (Android 6 and 7) world (compatible with Android 4.0 upwards).

To view the considerable capabilities of the app, please download the instructions.

No mobile network coverage is necessary. This app uses your device's built in GPS. All that is required is a clear view of the sky (the GPS signal propagates through wood and plastic; the app should work below deck on all but metal boats).

In short...
•Re-written user interface being the navigator into the modern world, using the Android5 and 6 user interface components
.•At the same time, I have taken care to preserve the look and feel of the original. Users of the original app should not feel lost.
•compliant with the new Android6 security model.
•Flash-light (Android5 and 6 users now have one anyway).
•Substantially re-factored code to make the app leaner and meaner.
•Limited support for GPX files (a common XML based interchange format used by many navigation devices). Waypoints or individual routes can be exported as GPX files. Waypoints can me imported from GPX files.
•Rapid entry mode for new waypoints.
•Make logs of where you have been, which you can annotate. I believe the log feature is refined enough to allow you to dispense with paper logs; I do.
•View logs as display on the phone.
•Share logs with Google Google Earth either on your phone or desktop computer.

If you have a previous version of the navigator then waypoints, this app should detect existing data from the previous version in a completely seamless way.

Preserved and refined original features include
•Designed by and for a sailor. You may find that some of the main layouts look “big and blobby”. Trust me, bog and blobby works at sea. Small and fiddly layouts do not.
•Store unlimited waypoints and routes.
•View waypoints alphabetically of by distance from your current position.
•Waypoints can have notes associated with them.
•Waypoints can be exported and viewed on Google Earth or as GPX file format.
•Display range and bearing to a waypoint.
•Routes (ordered list of waypoints) are included. A route can be exported and viewed on Google Earth or as GPX file format.
•When a waypoint is reached, a waypoint alarm can advance you to the next waypoint in a route.
•ETA to waypoint and VMG to waypoint are available.
•Cross track error intended for coastal navigation not for great circle navigation.
•If you are a sailing boat, engine hours can easily be logged.
•Crew on watch can now be selected; hours are now logged.
•The log service can be paused.
•Logs can be exported and shared (by email) either as KML documents (viewable with Google Earth) or HTML documents (viewable in any web browser).
•A barometer monitoring service is available for phones that support a barometer sensor (not many phones do). You can view barometer readings recorded for the last three days, and the barometer service continued to run if you leave the app, make phone calls or whatever.
•Anchor alarm watch service. Alerts you if you have moved more than a pre-defined distance.
•Not only is there an anchor alarm, the app can send text messages to another phone if your boat should start moving. Of, if the anchor alarm is set, you can send this app a text from a second phone to enquire where your boat is; this app will respond with a text message. This feature is not intended to be a substitute for keeping a proper anchor watch, especially if your boat is left unattended in a location where the anchor is likely to drag.
•Limited text to speech on the "Waypoints" view.
•Once started, the log, anchor and waypoint alarm services will continue to run, even if you quit the main navigator application. They will continue to run while you make phone calls or use your phone for email, Internet browsing or pretty much anything else.
