Interested in tornado and wind damage assessments? Wonder how they rate a tornado from EF0 to EF5 without guessing? This app is the answer!

We've condensed the Enhanced Fujita (EF) Scale into one easy to use app. Follow the on-screen dialogs as you select your damage indicator based on the damaged object you're looking at. Next select the degree to which the object was damaged. Finally adjust the slider for any variability in the construction. If the building is poorly constructed, lower the windspeed and vice versa.

Version 1.0
Basic DI - DOD - construction variability functions

Version 1.1
Added pictures to the DI and DODs!

Version 1.2
Fixed pictures that weren't displaying correctly
Added about & share buttons!

Leave us suggestions in the comments or by emailing us! Give us a good idea and we'll try to add it for you.

*** PLEASE REMEMBER: This app is for reference purposes only. Doing a real damage survey takes knowledge and experience you can't build into an app! Official damage assessments are the business of the National Weather Service and their delegates! ***

Interesting But...

It's a detailed and specific analysis of tornado damage to various structures. Allows the user to determine the severity of the storm from observed damage. It's good but there are fewer actual photos or graphic illustrations in the newest update.

Worth more than the price!

For those who do damage surveys this is a great find! Nice to see everything integrated into a format which fits fine on an iPhone. No need to lug a laptop around or some printouts to remind you of classification scales...
