I'm a developer and interested in the app. if we can't find the apk I can look at maybe regenerating it. I havn't really used cordova (the platform it's on), but I can probably figure it out.
Best thing would be if we can get it uploaded to the play store.
Re: ipad, it's an app built on a platform that is supposed to make deploying to both iphone and andoid easy. That being said, I don't have an apple developer account, so I can only go so far.
