Access Together allows you & friends to crowd-source community accessibility.
We've been working together over the past year on a mobile web app in addition to a desktop site.
The goal of Access Together right now is to gather reliable accessibility data about venues. Users are able to search the database for locations that meet their specific accessibility requirements.
When visited on a mobile device, the service allows the user to add accessibility data about a location, adding to the quickly growing list of venues.
The app was recently added to Foursquare's app list, making it even easier to accessify your community when you check in to Foursquare. Get on it!
