User reviews

It is so cool

Wow! This app is so cool! Users can know all the faults around the world! It is really amazing app!

only will show my risk factor

How do I get it to show me Local earthquakes?

App doesn’t work

It asks for your phone number to recieve a verification code, but once you do, it asks to update the app and won’t text me the code. Complete waste of time and might potentially be stealing your personal info!

Does not have functionality as shown in preview

Version 4.1.0 and website - I cannot get anything other than different versions of risk maps. No way to access the individual building risk assessment screen as shown in the first iOS App Store preview screenshot.
Very suspicious as other reviewers have complained about this for years, yet not addressed!
