gadgetbridge for android is amazing also itd for linux is great. I would say don't use lift to wake as it's a bit too sensitive IMO and drains your battery super fast. Know that some apps like the stop watch get interrupted by notifications so when using those apps I turn notifications off. Same for the timer app it has the some indication vibration as a notification so you should turn off notifications when using that app. Long press on the wallpaper to get options to change the color schemes and such. Such a cool feature I like to change my color schemes a few times a week. Don't forget to put the watch in sleep mode when you sleep otherwise it will be vibrating all night and the screen will keep turning on. Not required but I keep an eye on the github repo to see what issues are being reported and so that I know when new releases drop. Also when you first get the watch be sure to update to the latest release.
