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

Weve 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 youre 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
NO ADS!

Version 1.1
Added pictures to the DI and DODs!

Version 1.2
Fixed pictures that werent displaying correctly
Added about & share buttons!

Leave us suggestions in the comments or by emailing us! Give us a good idea and well 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 cant build into an app! Official damage assessments are the business of the National Weather Service and their delegates! ***
