I absolutely hate to low rate this app but after more than a year of using it I have noticed I have huge battery drain and very sluggish performance on my watch. Sometimes it even takes 6 or more seconds just for the main watch face to appear whereas the default samsung and galaxy store watch faces appear less than 2 seconds. I don't know if this is a samsung issues or a facer issue but regardless it has made it to where I'm forced to use stock or galaxy store faces exclusively.
