ERG for iOS

Great mapping, should integrate an auto wind direction

Works well! Cool functionality.

Eventually, you remember what the placards mean.

This app functions better than most paid versions that are available.

5 stars cause it’s super convent and handy! Only suggestion is making the wind direction option easier to maneuver.. could be a bit confusing to use :)

Could use a dark mode for working on scene at night

This is a great app. So much better than the book. I suggest when in the orange section have the “protective distance” icon at the bottom green instead of grayed out and/or have the green highlighted area in the evacuation section a link to the protective distances. Great app

This is the standard reference for hazardous materials.
