Rating plugin (or embed) that works with Android and iOS?

Hi,

here’s a somewhat tricky question: Do you know any rating plugin or embeddable service (like Polldaddy) that can accomplish all the following:

1. Be embedded on several places (rating on several sites, where a vote on site A is also registered on site B)
2. Work on both Android and iOS.
3. Possiblity to end voting after a specific date but still show the old voting result.

I’ve tried so many plugins and the one that almost made it was Polldaddy. Any ideas? I’ll be using this on http://www.codeandme.se where people can vote for app ideas. I’d like the votes to carry over from other sites should other people want to embed the rating there. It also has to work on smartphone. The Polldaddy rating shows up on iOS but you can’t interact with it, and the rating of app ideas should also be able to lock down once the product reaches App Store / Marketplace but still show the final voting result.

– Do you know any way of doing this?
