Author Dan Q reverse-engineered the Travelbound Android app by intercepting its network traffic in a rooted emulator, discovering it fetches itinerary data as JSON from a simple authenticated URL.

He replaced the 43MB app with a Ruby script generating a password-protected 0.05MB HTML page containing the same itinerary content minus tracking and advertisements. The resulting webpage supports copy-paste, print, bookmark, and cross-device access that the original app lacked.
