Install the Grytics App in your group
During the summer of 2018, Facebook introduced the App directory for Groups.
This allows group admins to install quickly apps for their groups. Grytics is part of this directory.
In order to use Grytics ( and keep having the data updated), group admins have to add the Grytics app through the group settings. How to do this ?
First go to your group homepage
1- Click on “More”
2- Edit group settings
3- Add apps
4- Search for Grytics and click on it
5- Then on Add and its done !
