Update on the Navionics/MxMariner comparison


I've an important update on the comparison I did a while ago between MX Mariner and Navionics chart software.

I recently had an update on my HUDL 2 which has updated it to the latest version of Android, called Lollipop.

Since the upgrade the HUDL has been marginal in storage space, in some instances preventing application updates or downloading new applications.

So the Lollipop operating system uses more storage space, but I really should have more space, so I went digging to see what was using all the space up.

The two largest applications on my HUDL were Navionics, which uses just under 71 Megabytes of RAM.

But blowing that out of the water by far was MX Mariner which uses a whopping 380 Megabytes. 5 times more space than Navionics.

I guess this is caused because MX Mariner is essentially a collection of scanned images of charts, which uses a large amount of memory.

Compared to Navionics there's a vast memory overhead.

As you can imagine, I've deleted MX Mariner and freed up the memory on my HUDL and things are now back to normal, no insufficient memory messages any more.

Just something to be aware of if you're comparing the two together.


  1. Interesting - no idea how MX Mariner can manage on my phone, but then I figured the data is probably on the SD card - must check... do you have an SD in your Hudl??

  2. Hi Steve. It's really only owners of devices that are marginal on storage space that would be affected.

    In my case the HUDL was fine until Lollipop was loaded which needed a lot more storage space than Jellybean.

    MX Mariner doesn't allow being stored on an SD card, it has to live in device storage unfortunately, which is why I had to delete it in the end.

    I'm now busy Googling ways of freeing memory. On a phone its easy. Its not so easy on a tablet.
