I am having Mi Band its really budget band in price point. Actually it is more accurate. It tracks your activity accurately. There are many options in Mi application. First you need to download Mi FIT application to see your activity which is track by your Mi Band.
There is walk tracking your movement tracking. I mostly like Deep Sleep option in that Band. Its really awesome and accurate. You can track your Deep Sleep when you were in deep sleep. Battery backup of band is really good for one month battery backup. Really if your Budget is low then Go for Mi Band.
