GPS navigation offline

Sounds complicated!

I know very little about GPX routes (except what I just Googled) but it looks like the standard format is xml. You can parse xml manually in Thunkable but if you can convert the GPX data to JSON – for example, alltrails.com allows downloads in JSON Track format and also has a converter for other formats – then you can manipulate that data however you want in Thunkable relatively easily.

I’m not sure how you would do that. Thunkable has a location sensor but I’m fairly certain it requires an online connection.

There’s no built-in navigation system in Thunkable. You’d have to code it using the Thunkable blocks. I can’t even begin to imagine how to do that but I’m sure algorithms exist that you could follow.
