I'd like to analyse my sleep as it's something I think may be an issue. Fitbit is one of the devices on the market that does this and there are mixed views on its usefulness. Any experiences or alternative recommendations to add?
Sorry, can't really contribute to that. This is what I consider to be the weakest feature of the device (and I've not been tempted to try it yet).
Also I rarely have problems sleeping! So don't feel I need help/analysis of that part of my day.
But in all other regards I think the Fitbit is a very impressive device, it really has highlighted potential areas of improvement in my daily routine and I've definitely been more active since I stated using it.
I think we're only seeing the start of health interactive devices such as this, there's a long way to go, but huge potential and much money to be made by the company that really nails it.
