Yes, Health Connect is supported on the Android app. As long as Samsung Health is set to write to Health Connect (Samsung Health → Settings → Connections → Health Connect), NutriTrace can read steps, sleep, heart rate, weight, and exercise from it.
Honestly though, this path hasn’t had many testers yet, so if you give it a shot I’d really appreciate a heads-up on what works and what doesn’t. Feedback (positive or bug reports) is welcome on GitHub.

Not directly. NutriTrace doesn’t record steps or GPS itself; it reads them from whatever’s already tracking you (Health Connect on Android, or Fitbit/Garmin/Withings via their cloud APIs). So if Google Fit, Samsung Health, or your watch is counting your steps and logging workouts, NutriTrace will pull those numbers in and chart them alongside your nutrition.
