Bolt (Firebolt) app for iPhone and iPad

Firebolt is an application designed for fire departments to simplify
your mapping. It takes your static PDF files you may already be using
(or printing) and puts them into an interactive iPad application.

With this app, you can load your grid of map pages and just by
clicking on any grid square, the application will instantly load that
map page. You can then swipe up, down, left, and right between your
map pages, or use the built in navigation.

While GPS and Google Maps are great tools, nothing can replace fire
department maps showing all hydrants, addresses and roads. This app
allows you to take that huge mapbook out of the front of your engine
and replace it with a slim iPad!
