An opensource react native based Cycling computer

• I should be able to see live data for power, hr, cadence, speed, altitude, and distance on screen [ ]
• Activity:
  • I should be able to start, stop and pause an activity [ ]
  • When an activity is running, Power, hr, cadence, location, altitude, speed, etc should be recorded to the DB [ ]
  • When paused, no data should be written to DB [ ]
  • When stopped a TCX file of the activity should be written to disk [ ]
• sensors:
  • I should be able to list discovered sensors [x]
  • I should be able to pair/connect to a sensor [x]
  • I should be able to disconnect a connected sensor [ ]
  • I should be able to list already paired sensors [x]
  • I should be able to delete already paired sensors [x]
  • The first type of each sensor in DB will be the primary used for data [ ]
• Location:
  • I should be able to see my current location on a map [ ]
  • I should be able to see a track of where I have been [ ]
  • I should be able to re-center the map to where I am [ ]

• Display live data [ ]
  • Write data to "realtimeData" table whenever data is available, populate with empty data at launch. [ ]
  • set up observables on realtimeData table linked to widgets [ ]
• Integrate GPS location data [ ]
  • using https://docs.expo.dev/versions/latest/sdk/location/ , preferably without background task permissions.
• Create active Ride UX:
  • create rides table [ ]
  • Add fab button to start/pause/stop a ride [ ]
  • On start:
    • create entry in rides table with is_active == true [ ]
    • set is_riding in realTimeTable to true [ ]
  • On Pause:
    • set is_riding in realTimeTable to false [ ]
  • On Stop:
    • set is_riding in realTimeTable to false [ ]
    • set is_active of ride to false [ ]
    • set stop_time of ride to current time [ ]
    • set distance, elapsed_time, avgs, etc on ride [ ]
      • depends on data logging tables
    • generate TCX file and save to file system [ ]
      • depends on data logging tables
• Log Data in DB
  • create data logging tables [ ]
  • periodically (INTERVAL seconds) dump a snap shot of realtimeData into hr, pow, cad, loc tables. [ ]
• Add battery to ble lib supported services [ ]
• Mapping:
  • Switch to using Mapbox maps [ ]
    • use route matching API nitaliano/react-native-mapbox-gl#1493
  • Add mapbox navigation page [ ]
    • using https://github.com/homeeondemand/react-native-mapbox-navigation
  • Add functionality for storing offline map packs [ ]

• switch to https://wix.github.io/react-native-ui-lib/docs/components/lists/Drawer for ui components. Would be nice to have swipeable bluetooth sensor list items

A sensor should be:

*id: string (primary) 
name: string
type: string
is_primary: boolean
sensorType: string[]
created_at: number
battery_level: number

A locationMeasurement should be:

*id: alphanumeric (primary)

• Auto upload ride to strava
• Camera recording
• light service from phone flash
• Navigate to a point (Mapbox Navigation)
• ride a workout from intervals.icu
  • Need to support laps for this
• Customize screens
  • select which data to display
  • move widgets around
• detect strava segments
  • need a local geofencing algo for this
• climb pro type feature.
• Weather forecast widget

• View real-time data of all friends in your group ride
  • friends get auto-added by those you follow on strava
• Send notifications for group ride friends to gather at a specific point or if you have a flat.
• incident detection
  • record in a 1-minute buffer and save video if an incident happens
