Companion app:
The companion app is available on my github: https://github.com/pauljohnston2025/breadcrumb-mobile/releases/latest
Settings detailed explaination: https://github.com/pauljohnston2025/breadcrumb-garmin-ultra-light/blob/master/settings.md

The companion app unlocks powerful features such as offline map support and route loading. Currently, the companion app is only available on Android, but contributions from iOS developers are highly welcomed to expand platform support and bring these functionalities to a wider audience.

This is the ultra light variant of https://apps.garmin.com/apps/99d7ebcc-3586-4dbd-8684-08b5ce4ddd80, it supports more devices, but has limited feature set in order to meet the memory requirements of older devices. Only route and track display enabled, there is no 'smart' features such as off-track alerts, and no map functionality.

This is a datafield, not a full fledged app, it runs in the context of native activity.  

The datafield is expected to be used to cover the full available area of a round watchface.  
It will still work with non-round devices or partial layouts, but the full feature set of the ui will not be possible due to the limited space.  

To add datafield to a native app:
* Open the app (eg. running), you do not have to start the activity, just open it.
* Long press to open settings (or use the touchscreen to press settings)
* Navigate to Data Screens
* Select screen
* Choose layout - recommended full screen layout
* Edit data fields - choose the 'ULBreadCrumbDataField' from the 'ConnectIQ Fields' menu

A more thorough explaination for a different app can be found at: https://support.garmin.com/en-AU/?faq=3HkHX1wT6U7TeNB7YHfiT7&identifier=707572&searchQuery=data%20field&tab=topics

To edit settings from on device (on venu series):
* Ensure the data field is added to your activity of choice
* Open the app (eg. running). DO NOT start the activity, you can only edit before activity start.
* Use touch screen to slide up settings. DO NOT long press, as that only gives you access to the run settings (layouts etc.), not our settings
* You should now see a menu 'ConnectIQ Fields'
* From here we can select 'ULBreadCrumbDataField' and modify our settings

Settings can now also be now be edited through the alerts menu (on venu series):
* Ensure the data field is added to your activity of choice
* Open the app (eg. running). Start the activity.
* Long press the bottom button to open run settings
* Click Alerts / Add new
* Scroll down to 'Connect IQ'
* From here we can select 'ULBreadCrumbDataField' and modify our settings
* Opening the settings again can be found in the alerts tab (click 'ULBreadCrumbDataField' then modify settings)
