The absolute worst pedometer I have ever used. It tracks THOUSANDS of steps that other trackers do not. For example, as I write this review, Google Fit has my steps at 2.3k for the day, Samsung Health has my steps at 2.5k steps for today, and this app has my steps at 4.7k. Only download this if you want your tracker to tell you that you walked 5km while you were sitting on the couch.
