MapCalipers is a flexible mapping toolkit (built primarily to help you defeat your friends in "Jet Lag: The Game", a Hide and Seek Transit Game!) The iOS app helps you pinpoint your target’s location within defined boundaries, steadily shrinking the search area using interactive tools like “Radar” and “Thermometer”. Leveraging standard GTFS data, the app overlays precise transit lines and stops onto your play area. Use the built-in analysis features to determine which routes and stops your target might be hiding at, then use the dynamic mapping tools to track them down! Using GTFS transit data is optional. Note that GTFS data may not be available for all cities and requires prior server-side setup. See the linked blog post at https://joshspicer.com/mapcalipers#self-hosting for more info and for self-hosting instructions. ** Please email me your city's GTFS info if you'd like me to put it on the default sync server for all to enjoy! ** This app is not affiliated with "Jet Lag: The Game Hide and Seek Transit Game" on Nebula.tv and YouTube.
