When I added the watch app to CalenGoo, watch apps were integrated into the apk file of the main app. I.e. inside CalenGoo there was a small "CalenGoo Wear" app, that was automatically installed on the linked watch when CalenGoo was installed.
Then Google tried several things to reduce the download size of apps. Instead of using apk files they are now using aab files. An apk file contains icons/images and other resources for all display sizes and resolutions. Using aab files Google can create specific downloads for each kind of Android device, which results in smaller downloads. And it seems that they also wanted to prevent users without a watch from having to download the app with the watch app included. So they separated it.
"CalenGoo Wear" is now a separate download but is linked to CalenGoo (because it does not work without CalenGoo being installed on the phone). I had created this separate "CalenGoo Wear" app a few months ago and uploaded it to Google Play.
However now I have seen that I have to request a separate review of the "CalenGoo Wear" app. I have requested it but when they tested the "CalenGoo Wear" app somehow the text was cut off on their device. I have fixed it and uploaded a new version. It might take a few days for the review to complete and maybe I will have to make further changes. I will post here when it is finished.
Kind regards
