The fitbit charge 4 has built-in gps and a range of workout modes. The app is easy to use and tracks steps, heart rate, sleep cycles, physical workouts even if you do more than one type of workout.

I love the monochrome display which is very masculine/high tech. I mainly just really love that it's rechargeable, and that it looks so sleek.

When it gets to one bar, i plug it in when i'm not using it. This charging unit makes it easy to know it's on. My only complaint was the original bands broke in less than 6 months twice.

The band is hard and not flexible, unlike apple watch and garmin, which have soft silicone bands. The fitbit charge 4 is nothing more than a heartbeat sensor.

Fitbit has terminated support for the windows app. It's not fixable now!

Amazon customer service sends you to fitbit and won’t do anything. Are you kidding me?

The product is not durable. This is my second fitbit and it has met the same demise as the first one, only sooner. The first one has the anchor point snap off after 12 months.

The gps takes several minutes to connect, which is absurd. The gps drains the battery completely for activities longer than about 3 hours. It takes the charge, but it dies within an hour.
