My first iPhone app attempt

Hi guys.

So I am a total NOOB.

I'm reaching out for advice on my first app attempt

Here's what I want to do.

I run a personal fitness training business.

I use iCloud to keep multiple client calendars in iCal.

Each one of these calendars has a URL

Id like to develop an app in Xcode that allows the client to retreive that URL somehow, and then the calendar events show up on iCal on the iPhone/iPad.

So at the end of the process the new client only has to do this once and then they are subscribed to their calendar forever.

Is this possible guys?
