### 5/5 — Suggestions

*2022-07-08*

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 :)

### 5/5 — Suggestion

*2022-03-22*

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
