Nonvisible activity tracker?

Does anyone have a tracker they love that is not visible that tracks general activity level, calories burnt, etc? Thanks!

I just use my iPhone's step counter - New York Times did a study (http://mobile.nytimes.com/blogs/well/2015/02/11/better-fitness-through-your-phone/) that found it to be pretty accurate, so I just set my activity level here to sedentary, keep my phone on me at all times, and eat whatever calories it gives me. Granted it doesn't monitor heart rate, so wouldn't help for lifting heavy weights, or some other activities, but for me it works great.
