Android marine instruments app

Hi guys

I am creating an Android app to display marine instrumentation data (at the moment from a signalk server source). I can fit 2 instruments on a 10 inch tablet and a menu allows you to choose different pages of instruments. I have attached some images so you can see what I am doing. Instruments are either full height single reading, half height dual reading or a wind gauge.

I am in the process of collecting the instruments onto various pages and
so my question is - if you were going to use this app then what instruments would you like to see grouped together on each page?

You can cycle through depth in Meters,Feet,Fathoms. There is a night mode as you can see and I am working on converting between magnetic, true, apparant etc. for heading and wind gauge. Engine gauges will be next. Anything else you would like to have ?

many thanks in advance

Re: Android marine instruments app

How are you getting data from sensors?

Re: Android marine instruments app

Wow nice job. How are you doing the refresh rate for wind direction. if you allow selection of instruments per page then the user will be in charge and happy. Great job.

Re: Android marine instruments app

IMO the best idea for apps like this is to allow the user to select which instrument(s) appear on which page. Also, it might be a good idea to allow more than 2 instruments on a page. The reality is that few tablets have useful viewing in full sun from far away. So big displays aren't as useful as it might seem. Having a wireless tablet right at hand with 6 instruments with easily read data would be really great. I think you are onto something.

Re: Android marine instruments app

I'm excited about your work.

#1. I like the concept of a dual-ring compass. Where the outer ring is your heading, and the inner ring is relative bearings. Switching between "heading up" and "north up" determines which of the rings is fixed and which rotates. Around the compass you have moving markers for stuff like apparent wind, true wind, bearing to waypoint, opposite tack heading, etc. I think this brings a lot of information together in one display.

I put together a prototype:


#2. I'd like a screen that shows the dynamic vector forces of wind, boat speed, drift/current, and vmg.

The wind direction data comes through the signalk server and that regulates the refresh rate.

Yes I appreciate allowing users to create their own pages by selecting the instruments per page is the way to go. That will be done eventually.

OK I will experiment with different sizes of instruments for more on the page.

Only joking, I would actually pay for an app like this, apart from depth/log my cockpit nav is a sony xperia repeating from openplotter on a rasp pi.

Being able to read nmea would probably be of interest to many. And custom read outs for the XDR sentence , I have a few engine thermometers which would be nice to see up top.

Great idea, best of luck!

Re: Android marine instruments app

There are a number of apps out there already that have similar functionality. Something for OP to consider, is how do you differentiate your app from the others?

So it's a wired USB connection from NMEA source to tablet?

Re: Android marine instruments app

Furimo has the !st Watch radar which sends data via wifi to Mac iOs devices like I pad/iphone.... but not for Android.

How about somethingsimilar for Android?

Great idea, and long overdue.

Why not create a swipe function so that each instrument can be displayed in turn quickly by simply swiping left or right? This would allow you to display each instrument as full page for maximum visibility but allow very quick switching between displays.

You could still allow the user to program more than one instrument per page if so desired, and choose which instruments they wish to display together.
