Can I use this fitness watch without a phone?

You first have to pair it with your smart phone in order to set up the tracker including the current time/date and personal information such as your age, height, weight. Once you’ve been through the initial set up there is no need to keep it connected to your smart phone in order for it to function correctly. You don’t need to have your smart phone with you and you can still read the tracking result on your tracker the real-time heart rate, steps, distance, pace, exercise duration and calories burned, except for the sleep tracking result. The fitness tracker will collect your activity in real-time and store it locally, the benefits to pair the tracker with your smart phone is syncing these data to the paired apps so that the tracking result can be neatly presented for reading and kept record.
