It seems that this trick to read the quantity of rows in the device has not posted.. so here you are 
- Open the app with the full screen
- Open the developer Tool
- Select Console
- Write AppModel.rowCount
The result is the row count after the security filter (if itโs in use)
The AppModel.Tables will give you more information as well..

What is the developer tool? How can I enable it?
It belongs to Chrome browser. Three dots from the upper right corner > More tools > Developer tools
