When you start up MCPE, hit "Play" and at the top right hand corner, hit "New". You should be presented with some options like world name, world type, etc. At the right side, there's a seed blank. Just type in your seed here.

To find out what your world seed is, hit "Play" and at the top right hand corner, hit "Edit". All your worlds should display their seed now.
