🔧 Fix this

Ideas a builder, maker or community group could start on:

  1. Update the app to support infrared or low-light camera processing for heart rate detection.
  2. Implement a feature that allows users to toggle between camera-based heart rate tracking and integration with wearable devices.
  3. Develop a screen-based light calibration mode that uses the phone's display as a dim, localized light source instead of requiring room lights.

“The heart rate tracker requiring bright lights sucks. It’s dark in the morning and I’m not turning on the bedroom lights to wake up my wife to use it.”
