Whom are you targeting? I have never heard of a gift registry, so unless you are targeting only people that already know the term, try to describe the general purpose of your app. Copyblogger is a nice resource on how to write marketing texts and headlines:

For example, your headline (Welcome to..) is basically meaningless. Instead, try to describe your service in it. AirBnBs headline says "Find a place to stay". Maybe yours could say something like "Manage your gift-getting"? (Wikipedias description of a gift registry).

Also, read up on typography, a few small changes can have a great effect:

For example, your headline (Welcome to..) doesn't differentiate itself from the text and therefore doesn't grab the viewers attention. Try to squint your eyes and move back from the screen, you can't see if it's a headline or a part of the text. Try making the font larger and bolder.

I wish you good luck on your endeavor.
