How to set Joomla template for user/visit
<p>I want to use specific Joomla template (with no navigation, no top and bottom) for users that connect to website through my mobile app with iframe in it. I assume that this users will start connection from specific address with tmpl param (or something similar) but is there a way to lock this template for these users?</p>

<p>Maybe there is some plugin to set template in session data and override default template choice?</p>
