tablet ap

I downloaded the Duo ap from Google play but it said my gmail was in use (the gmail I use on the web Duo) so I used a different email. I got the ap but it is not connected to my wed lessons (not surprising with different email). i thought I could continue my regular lessons on the ap when I was away from home e.g.
What have I done wrong, do I uninstll the ap and start over and how do I get regular lessons on ap. Please help.
