My old Fitbit HR just crashed on me (it's over 5 years old) so I was looking into getting a new smart watch. The Apple watches are insanely expensive, but I would like something than can pair with my iPhone XR that will track my steps/heart rate. I'm a casual gym go-er/power walk taker so I don't need anything super extreme, just something simple that's not $300. Any recommendations/advice is appreciated.
