Ask IH: looking for feedback on DreamFort

Hi,

first of all I need to thank the awesome community, reading all your posts and seeing the awesome things you build has finally motivated me to do things properly. So again - huge thanks for that!

My first attempt at a product is a dream journal with a specific focus on making it easy and quick to write down a dream, DreamFort.

I'm interested in what you think about it.

Do you like the design?
Do you see any way to improve the text? I'm a non-native English speaker, so any help there is enormously appreciated.
Do you think just a landing page can work for such a simple app? Or is it better to just build it and then let people download it?
Do you have any other feedback?

Funny sidenote:
If you look at the page on mobile, the newsletter signup looks like a cigarette.
