  • If you have an old phone, it won't receive notifications.  But does sync notifications on newer phones. 
  • Have to install an app from the App store and then restart your phone..But then it syncs up great. 


If you want a great tracker without the high price this is highly recommended.  It is pretty simple to setup and the battery lasted four straight days without having to charge it up.  The tracker seems pretty accurate when I workout as it show my heart rate and calories burned.

  • It’s great with counting your daily steps but the treadmill sport on it wasn't accurate. It is accurate in the timing m
  • Getting the HR data into the Apple health app took a little time to figure out.  To get it to synch, you have to use a swipe motion in the app
  • Some issue with tracking sleep that is interrupted with times of wakefulness. It seems that standing up too long during a sleep cycle will kick you out of the sleep measurement function for the day.


This is an excellent price for a great product.  The watch face is the right size as it is easy to read and the band is light weight so it is comfortable to wear.  It is easy to setup and no complications of needing any SIM card.

What is TDEE?

The amount of energy you eat each day in calories is TDEE, the total daily energy expenditure. TDEE is best calculated on the basis of your BMR or basal metabolic rate and level of activity. BMR is the calories you burn at rest every day. 

Your total daily energy includes all the energy you use when sleeping, working and even eating. If you are trying to get the right diet for bulking or cutting, it is important to know your TDEE. 

Your TDEE is often called the calorie maintenance level of your fitness products. This is the quantity of calories you need every day to keep your weight. If you know your total daily energy expenditure, you can either add calories for bulk per day or reduce fat calories.
