When showing off a brand new app with no existing userbase, please show or tell what your app does before waxing poetic about its beauty. If it hadn't been for the HN headline, I wouldn't have stayed on this page long enough to see what the app did.

CORRECTION: I missed the intro animation when I opened the link in a background tab, and somehow got left with a masthead image with just three icons on a blank phone, not even the download link it showed after I refreshed.
