Early of this year, I went to Hong Kong. During this trip, I bought a new toy, xiaomi miBrand. This is a fitiness tracker. It can track my steps and sleep m pattern. I love it. That is very light, a bit little lighter than my old watch. Moreover, its battery can last for a month. In addition, it supports all Bluetooth phones, you do not require to use xiaomi phones. All you need to download their fitness app, miFitness. Lastly, it only costed around HKD$150.
Well, there still are some drawbacks. Firstly, it cannot track heart bit. Besides, you has to use their fitness app. This is using a chinese map provider, it cannot track my running track in Australia. However, it only cost HKD$150, I still think that is a good entry point to try this kind of fitness armbrand.
