Some iPad help required please

Do I have to have a website already set up to use the ipad/android app?
If so, why bother with an app, just go to the website. Or am I missing something?

How do I set up client raw files?

Sorry for all the questions but the excellent Weather Display software has some very advanced functions (for me!), which I have never really understood (FTP etc.).

Any help much appreciated,

Simon

there is so much more you can do with an actual app running on a phone compared to just viewing a web site on a phone
i.e you can select which graph to plot,etc etc
e,g for the Android version there is voice output (I will hopefully get that working on the iphone version)
