Twinstang is a web application for pilots to digitally log and track their flight hours. It is built with Ruby on Rails and also works on the iPhone.
Twinstang is Spitfire Sky's first successful web application built in our spare time and on our own dollar. Over 1,000 flights have been entered by approximately 100 users and another 30 users (as of Jan 01, 2009) are in line for their invitation to the beta. Sign up for the beta.
Scott Motte, a private pilot, developed the idea and continues to work on new features.
