I learn this technique from Mr. Ticks and it sure simplifies having to re-install apps when you have to do a or multiple factory resets. I download the apps i’m going to use to my phone. Use App Backup and Restore App make a backup. Connect my phone to the computer and download the apps from my phone. Put them in a file on my computer. I now have a copy on my computer which I can also use on all my watches. Connect the watch create a folder in File folder called Apps. Now you can install the apps from this file. After a factory reset load all your folders back onto the watch and re-install apps from folder. If you load App Backup and restore on your watch, when you update an app, you can keep a backup of that update on your watch to use for future installs. You can also store apps in the folder, from you phone that you may not be using but may want to try and can install them at any time from the folder.
