I bought this fitness tracker for my wife and she used it a very few times but decided she preferred her phone app.  It has all the customary features of this type tracker.  That's the main reason my wife prefers her phone app because the only feature she uses is the pedometer.

Rechargeable battery charges via USB, 90 minute charging time.  Bluetooth 4.0.  Has numerous features my wife never even checked out.

Here are the main functions listed in the user instructions:
  • Time
  • Steps
  • Distance
  • Calories
  • Sleep
  • Heart Rate
  • Blood Pressure
  • Phone Tracking
Please look closely at the actual, not stock, pictures.
Free shipping included.  Thanks for looking!
