Features include: Call notification Call information Call location Map layers Address history Directions Responding Apparatus-specific features including AVL and personnel on board BATTERY CONSUMPTION Continued use of GPS running in the background can dramatically decrease battery life. iSpyFire has been designed to use GPS and other sensors sparingly. The app relies on location data only while you are responding to a location or when you are attempting to create a new location (except when an apparatus is in AVL mode, in which case it is constantly checking).
Intterra Field Tool
Read full descriptionHide full description
Intterra Field Tool requires a login for Intterra, the robust web app decision support system that provides intel, mapping and analysis for emergency response agencies. Intterra Field Tool complements and extends the use of Intterra to field users, with the benefit of working offline and syncing with Intterra automatically when internet connectivity is good. By design, it does not have all the capabilities of Intterra. Intterra Field Tool allows viewing, collecting, and sharing emergency response information in an interactive map with extensive map tip details. Disclaimer: Continued use of GPS running in the background can dramatically decrease battery life.
