Make the app available outside the US
I am a US citizen who lives abroad. I am registered to vote, and would like to remain active in the political process. It would be really helpful if I could download your app to my phone rather than needing to use the website. There are a lot of engaged citizens who live abroad and making the app available outside the US would help keep them connected to what is going on.
I agree with Jenny, I live in Spain along with, I would guess, thousands of students, English teachers, servicemen and women who are American citizens and are registered to vote. Having an app like this would help keep us connected to what is going on at home especially since calling representatives from abroad can be problematic.
