Office Marathon

An example app for background location tracking in Expo

With this app, you can measure your total distance traveled within the office or your home. It's a simple app with the following structure.

• app - is our entrypoint for the app, combining all providers.

• providers/asset - loads the custom font, using Expo Google Fonts.
• providers/navigation - sets up our app screens and navigational strucutre, using React Navigation.
• providers/theme - handles some slightly styled components for us, using Dripsy.

• screens/onboarding - this is where the app asks the user for background location permissions.
• screens/distance - after the permissions are granted, the user can start/stop/reset location tracking and see their distance.

• services/location - calculates distance between points and wraps the functionality in hooks for easy access.
• services/location/storage - simple helpers to store location data in local storage, using Async Storage.
• services/location/track - simple helpers to manage background location tracking, and the background task itself.
