This fitness tracker is your perfect companion for maintaining a healthy heart. A heart rate sensor in this fitness tracker helps collect your heart rate data for over 24 hours. You can always check your increased heart rate and act immediately to avoid mishaps. When we go to sleep, our heart rate changes during different stages in the sleep cycle, and this data is tracked by this fitness tracker using a heart rate sensor to monitor your sleeping pattern closely. This fitness tracker also helps to maintain good sound sleep habits.

There are various sensors present in this fitness tracker that help track different stages of your sleep.

Waterproof and battery

Generally, we remove our wearable wash when we plan to wash our face or go in the rain. We always stay worried while exercising, so our wearable doesn’t get damaged by excessive sweating. This wearable device has an IP68 rating which means your device offers protection against damage caused by dust and water. You can now have the freedom of exercising while wearing the device as excessive sweating won’t affect your device working. Even when you plan to wash your face, you may keep your wearable worn on your wrist as even a splash of water accidentally won’t damage it.

The battery capacity of 230mAh offers enough power to enjoy features and long-time wear without worrying about frequent charging. The battery of this wearable provides 25 days of standby time. You may plan to go on the trip, and this wearable battery can last up to 10 days under daily use mode, so you won’t have to worry about charging on your journey. Now, if you want your wearable to last even longer than ten days, you may use it for 25 days in basic use mode to avoid worrying about charging.

Exercise & apps

The way to live a longer life is by walking and staying fit. We always try to walk but are unaware of the distance traveled or calories burned, which doesn’t give us an idea about the particular session data. This smart wearable watch will help you obtain the required data during the walk session by helping you get data about calories burned during your special walk session or throughout the day. You can also receive data about the distance covered during your walk session. This wearable can keep you updated about the weather for up to the next three days so that you can plan your work accordingly. The alarm function is vital in awakening you, so you never get late to work or important meetings. Many of us sometimes forget where we kept our phones; this wearable will help you find the smartphone’s location by ringing on your phone.


The capability to monitor health functions offers you healthy life. Haylou RS4 LS12 delivers a new look every day with different watch faces. The longer standby time and use time ensure you forget about charging frequently. The protection against water ensures you can wear this smartwatch during every water-related task.
