can unreal engine be used to make wear os apps for wearos smartwatches?
check out the link below to the UE4 FAQ. it lists all the currently supported platforms. so unless your watch relies on something like html the answer would be no. though i seriously doubt the watch would have much in the way of processing power, at least less than a cellphone IMO. so it may be hard to make something simple enough to run nevermind the issues with getting the program onto the device.
