Under the hood, the Amazfit Arc comes with some good functionality features including the accelerometer and sensors that assist in keeping track of your steps, sleep phases and an optical heart rate monitor that gets to calculate your pulse. First things first, out of the box, you will need to download the Amazfit Arc application for your iOS or Android smartphone for easy use with the fitness tracker. The app allows you to set up your profile by entering the key data including your age, weight and gender. Having done this, the tracker shall be able to keep track of all your activities including counting your steps and phases in sleep. Additionally, the device comes in handy in reporting on messages, incoming calls and act as a reminder by vibrating if you stay too idle for long. The vibrator can also be used to wake you up. Users who normally have their phone on silent mode will find the incoming call alert a useful feature that will enable them not to miss important calls.
When it comes to sleep, the Arc rates your rest with the ability to show you the total sleep time and when you were either in deep or light sleep. It performs better than the Fitbit Charge 2 as a sleep tracker especially for deep sleep timings but then as always it will be difficult to tell the accuracy of the tracker considering the fact that you will be asleep! For measuring the heart rate, you can get the accuracy or consistency with more than one measurement. This is quite okay but then if you are not on a budget you can go for more accurate trackers in the market that cost more.
