I had a simple fitbit and was looking to upgrade to one that did more. Step counting requires more than simple movement so does not keep track of all activities. It requires charging every 24- 48 hours ( my fitbit never required charging). It is very easy to use and understand. I would have rated it a 3 1/2 over all.

Fairly good health tracker, graphs all three heart rate, which is extremely accurate ,blood pressure which is close but not real accurate, & oxygen which is accurate. The only problem is the small battery size. This tracker needs a larger battery, it only lasts 24-30 hrs. That’s why i only gave it 3 stars. My other trackers have 110mah. Battery’s and last 5-7 days, full load. Don’t think i would buy again.

Reviews from purchasers :

  • Easy to use draw back is charging it often and does not count all movement if low impact
  • Needs larger battery, that would make all the difference , then it would be a great health tracker
