I would love to be able to use inches and pounds on my app. I don’t know kilometers... and it’s not letting me change it so that’s not helpful. I love the watch so far but I want to be able to use it.

The functions do not work accurately, (I only get 45 minutes of sleep each night - apparently) and some functions like BP and heart rate don’t work at all. The band faded after 3 months and it was winter. I’m constantly recharging and have to reset the personal data. If the band comes into contact and pressure is applied to my arm (caring a bag of groceries or carting a beach umbrella) the device falls off. I had to uninstall the first Lefun Health app and install this Wear app when the device refused to connect via Bluetooth. This Wear app won’t “Save” my correct height and weight. I’m now 2 1/2 feet tall a weight 352 pounds. Save your money and purchase an Apple Watch that is reliable. If you’ve already bought this piece of junk give it to a young child that needs practice resetting the data and won’t be disappointed when it falls off and they lose it.

Sorry to say that this really nothing more than a useless piece of plastic wrist jewelry. For some unknown reason the bloody thing keeps resetting back to 0600 on 01/01, sometimes when I move out of Bluetooth, range, sometimes when I’m still connected! No data whatsoever manages to get input as it’s never completed a full day without resetting. So, as a watch it’s useless, as a health monitor it’s useless, and all round it’s totally useless. Don’t buy it and if you get it as a gift see if you can return it. Only gets 1 star because I can’t go lower or even into a minus........

I like this app works well and has great graphics. I used it with The Comet watch and it did what it was suppose to do. Make sure you also pair your watch through Bluetooth or you can’t get phone calls
