What kind of exercise are you dong right now? You can select from 6 workout modes:
At this price point the waterproof feature is almost unheard of. Xiaomi took advantage of this and added swimming tracking which can distinguish between different strokes as well as measure number of strokes and the stroke rate giving you scores based on SWOLF (swim golf) to measure performance.
The band also allows you to count steps, distance, and calories burned as you walk and do other activities.
Set goals for yourself and monitor them. Mi Band 4 has sleep monitoring allows you to measure your total sleep time and differentiate between light- and deep sleep. It will record these results over time to show patterns, compare your data with other users, and provide recommendations on getting a better night’s rest.
Monitor your heart rate all day. The band has idle alerts: this is when it senses you have been idle for too long and it vibrates just to check everything is OK.
Yes the Xiaomi Mi Band 4 is a fitness tracker and not a smartwatch but it has the basics covered well. It has a pre-set watch face as well as a customisable watch face with general clock features like: alarm, timer and stop watch. You get notifications like: incoming calls, message notifications, calendar notifications and app notifications
Of course the band has a weather forecast feature and the all important ‘find my phone’ feature as well as a proximity sensor. Oh by the way, there are different ways to wear the band!
