Rungap for iOS exports GPS data as JSON file in the free version. This script converts it to GPX. Tested with python3.6. Might need to install required modules. Simply place either the metadata and data json files, or the complete zip file in the same directoryas the script and run it. Warning: Does barely any error checking

I'm a noob with this programming stuff.

The script first says it cannot find module pytz, if i remove that from the code:
When I run the script the newly created "__MACOSX" folder contains only blank folders with no content.

you'll need to install the dependencies. Run pip install pytz and try again with the original file

Hello

I have installed pytz but the newly created __MACOSX folder contains empty folders

Can you manually unzip the file generated by rungap and tell me what’s in it? Am 2. Mai 2020, 06:22 +0200 schrieb SpicyStingray :

Unzipped it manually then placed every file into one big folder, worked perfectly, thanks

Ah, I think I know what the issue was. Should work with the zip file now too
