HypeCycle Mobile

An opensource react native based Cycling computer

MVP:

  • 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 [ ]

TODO:

  • 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 [ ]
  • 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:

To Try:

Data Structure

Real Time Data Table

id: alphaNumeric (primary)
distance: number,
elapsed_time: number,
speed: number,
latitude: number,
longitude: number,
altitude: number,
heading: number,
heart_rate: number,
instant_power: number,
three_sec_power: number,
ten_sec_power: number,
cadence: number,
is_bluetooth: boolean,
is_wifi: boolean,
is_power: boolean,
is_heart_rate: boolean,
is_cadence

rides table

A ride should be:

*id: alphaNumeric (primary)
*start_at: timestamp / or just use created_at
end_at: timestamp
*is_active: boolean

settings table

A settings table to persist settings and config

*id: alphaNumeric (primary)
screen_brightness: number
is_auto_uploading: bool

Data Logging Tables

table: sensors

A sensor should be:

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

A locationMeasurement should be:

*id: alphanumeric (primary)
accuracy: number
altitude: number
altitude_accuracy: number
heading: number
latitude: number
longitude: number
speed: number
ride_id: string (foreignKey)
table: heart_rate_measurements
*id: alphanumeric (primary)
beats_per_minute: number
ride_id: string (foreignKey)
table: power_measurements
*id: alphanumeric (primary)
instant_power: number
ride_id: string (foreignKey)
table: cadence_measurements
*id: alphanumeric (primary)
cadence: number
ride_id: string (foreignKey)

Future Features:

V1:

  • 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

V2:

  • 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
