You get sleep data, but you get more sleep data with premium. If you don't have premium, it completely hides the area from you where the new charts are and the only way to see them is to dig up your past premium data. But even then you can only see for months that you had access to premium, it doesn't give you the data if you don't pay, despite it constantly taking all the same readings as normal.

I suppose it's not technically true they're keeping your data from you. What they're actually doing is refusing to crunch additional numbers for you and show you nice graphs for them if you don't pay. Normally this wouldn't bug me, but since it's already taking all my data and and since I know crunching those numbers doesn't cost 10$ a month when I already paid 150$ for it to do exactly what they're trying to charge me more for it to do...well, now I'm just rambling 😄 it bugs me is all, and I'd gladly try another manufacturer if I could find something more competitive.

I'm already on my 4th Fitbit in 6 years from them breaking (one of them the screen separated from the device. Just peeled out), so I don't exactly have confidence in their build quality anyways.
