Bangle.js time steadiness

I don't really understand. All you need to do is:

• Use any app that uses GPS enough to get a GPS lock so the GPS gets the time - maybe 'GPS Info'
  
• Go to https://banglejs.com/apps/#custom%20boot
  
• Click the 3 bars icon to the right of it
  
• Paste in the code above
  
• Click 'Upload'
  
  

Now the code will always stay loaded in the watch
