Wow! This is perfect. Unlike some gadgets I have purchased, the learning curve is effortless. Plus, it has automatic features I did not know I needed. Cannot recommend highly enough. A very well thought out tool to use with your health routine. If you take off walking for more than 20 minutes, the device automatically records it as an aerobic session. But it automatically keeps a daily and weekly total of steps as well. A great idea. I keep it on all day, every step closer to my daily goal of 10,000 steps per day. Whether running errands or taking a power walk, the tally is encouraging and accurate. It can be worn several ways, therefore, I have a place to attach it for every outfit I may wear.Get more detail about Hj-113 Pocket Pedometer.
