Trello - download for offline use?

I put this as a response on another thread but it is really a new topic, I think. So I post my question here:

I'm just discovering Trello and giving it a try. So far so good. I am wondering if anyone has a seen a downloadable version of the program for times when the internet isn't accessible. And, how to know if the downloaded program is safe. Is there a trusted site out there to get it from?

Other suggestions for downloadable project managers?

thx
