Up24 is a very good and well designed tracker. It is 80%+ accurate. It's accuracy improves by 5% to 10% as you learn and understand it's limitations. One regrettable limitation is it is not waterproof though I believe there are waterproofed versions available (waterfi?). The app works very well on its own with the option to pair it with a large variety of specialized apps. Make sure you get the correct size. It will be necessary to gently coax the free fitting design to your wrist. It does not have a display which for some may be a disadvantage. Lack of display is exactly why I love this band and it was part of Yves Behar industrial design principle. I have had many bands and jawbone bands rank supreme.
