SailFreeGPS

Hello,

I am an amateur sailor who has decided to create this app during a Transatlantic cruise.
I add periodically functionalities to this app when I have some free time.

✓ SailFreeGPS displays current position, course (COG), speed (SOG), max speed, Trip distance and magnetic compas.
✓ SailFreeGPS displays COG and SOG history to help you to see trim effect on your sails.
✓ SailFreeGPS filters GPS information for more accuracy average of an amount of last measure you can set).
✓ SailFreeGPS can share your position, COG, SOG to your friends.
✓ SailFreeGPS helps you during Man OverBoard manoeuvre (MOB). It store the position and lead you to it.
✓ SailFreeGPS display your track on google map.
✓ SailFreeGPS helps you during Regatta with its countdown timer and its departure line
✓ You can store up to 5 waypoints and activate a GOTO function with ETA (Estimated Time to Arrival computation)
✓ You can convert your track to GPX/KML file
✓ You can use it on every boat, motor or sail boat.

Compass is a very tricky sensor, some time not accurate or some time just not calibrated. In this case, just consider https://support.google.com/maps/answer/2839911?co=GENIE.Platform%3DAndroid

Guys this app is amazing!! I took coordinates from my Marine chart and entered into my phone and it's really working as the way I wanted. Excellent!

The best satellite map I found, and an anchor alarm that works

Brilliant. Shows what can be done with lightweight programming. Very small download. Very clear screens. Very useful information. Including the GPS coordinates which are not only useful for chart work but make the app useful on land as well to share for houses up lanes without numbers. Well done FredB! Can we contribute a few € to say thank you?

I very much appreciate the information that this application reports however I was disappointed that the paid version did not actually save all of this relevant information. Specifically the map view and the screen showing the top speed average speed etc would be very helpful if it would be saved and could be open later..

I'm still learning the app, but so far I've been very impressed! I wish some power users would create an instructional YouTube. I still haven't figured out how to set a course with multiple waypoints.

Excellent app. Clear display with all the info you could need, including mob marker. Could even use it as a primary GPS if everything else failed.

This is the perfect quick sailing instruments app... it would be helpfull if there were a few more waypoints available, and if the history of the last trip were stored...

Nice big display of speed and course. A suggestion: leave off the GPS coordinates position window (put it in the menu) to give more room to display even bigger speed and course.

Really nice simple sailing app with clear display. Only seems to support one waypoint unless I've missed something, but that's enough to see your course details.

This is a good app if you don't need markers or depths of the water and you're within a tower to be able to receive data off your phone if not it's useless app

Totally agree with Erik Stielow - lots of nice features but it needs a start/stop button. Been suggesting that for months and get nothing but pushback from the developer.

Tried to use at sea, where else, dialog box requested update now, so could't use, not available offshore, major fault, s/b able to upddate later. Fair comment, but network distantly avaiable only over GPRS. Thanks

Great app ever Thanks to your job

Ott. W. Jul 16, 2020     

Very good app. May I suggest that you consider adding the ability to read a NMEA stream over WiFi (tcp or udp), and use that for the input instead of the phone / tablet's sensors?

If you turn your phone sideways it goes to Africa every time. The people who made this program must be from Africa. The way when she put in don't erase when and say that it's full that makes it difficult to use this program

Just got the update with adding more waypoints. FredB, you are doing awesome work. When you get a pay release, I will definitely pay. I normally don't do paid apps but yours is exactly what I want. Keep up keeping up!

Simple, with everything I need the most on the first page, and with the trace & map as a bonus. Perfect for my kayak trips :)

Excellent app. Just finishing an Atlantic crossing. Checked it regularly through out. Good work.
