Question about limits of e-mail sent in a shared applicaitons

 Hi, I have question about limits of e-mail sent in a shared applicaitons:

When I shared my apps to the users "toto", and in my apps i have sent 500 e-mails today (the limits of the apps), so does my friend "toto" can use this app to send also e-mail?

Thanks for your help!
