I have a basic GPS bike computer that cost ~$50. It's significantly more accurate than the Strava app I used to run on my Android (results are fairly consistent with the Garmins that my riding companions use), and can pair with heart rate and cadence sensors. It just doesn't have the mapping features that one gets with the higher-end Wahoo or Garmin devices.
