I dont have a tracker on my wrist or anything, but I like to use My Fitness Pal for free on android. I tell it I'm "moderately active" and how much weight I want to loose, gain, or if I'm trying to maintain.
Then I use a program called Sleep as Android. If you put it in your sheets with you it'll track how much deep sleep you get, wake you up with sleep cycle analysis and let you know how much REM sleep you got, how much you should be getting, ect. It also has a math quiz and other little games to turn off the alarm which I find helpful in getting out of bed on time.
All that's free, and I'm way too cheap for the fitbit and nike wrist bands lol.
