I tried to use the App Wizard in a way, which I think, it’s innovative.
My idea was to create an app that displays the current exchange rate for different currency in my country.

So, first I created a RSS feed which displays ONLY the current exchange rate.

As I selected 4 currency, the RSS feed has only 4 entries.

The problem is that the app, when it parses the RSS feed, it not only takes the current content but also stores the previous entries

So, even if my RSS feed is displaying, at any time, only 4 entries, like :
1 …
2…
3…
4…

And the App I created is displaying like 20 entries:
1..
2..
3..
4..
..
20..

I just wanted to create a simple and clear app. But now my app doesn’t look as interesting I thought it will be. As it has a lot of info in it.
