Primary development by Scott Parker (@jscottparker). Testing and other support by Katie Urey (@rbracket) and Peter W (@techieshark).
After this app is tested, we'll use it to collect data and feed that into a pedestrian and wheelchair routing application (probably powered by Open Trip Planner).
Mele Sax-Barnett (pdxmele) developed the first application and it can be found at her github repository.
