Preview and Publish a Site from the iOS App
The Weebly editor provides a pretty good picture of how your site will look when published, but you can also get an actual preview of both mobile and desktop. Tap on Preview in the lower right, and then choose from Mobile or Desktop by tapping one of the two buttons.
If everything looks good, tap Publish in the upper right to make your site live. If you want to go back and make more changes, tap Done from the Preview screen to return to the editor.
