Hey fellow HNers. I helped build this app along with a large group of volunteers in r&#x2F;CodersForSanders. I actually learned Swift to build this app in particular. It&#x27;s backed by a Rails JSON API. The Android app is another 1-2 weeks away from being finished.<p>As far as I know, this is the first time volunteers have come together and built a canvassing app for a campaign. The campaign heard about it, liked it, and asked if they could absorb it as their own.<p>Please ask us anything you&#x27;d like about its development, and any one of us on the team will be happy to answer.
