I am very happy to announce the terrorwarn beta sign up start. Visit terrorwarn.org and fill out the sign up form to become a beta tester. A web, iOS and Android app is in development, the release is planned for next year.
With terrorwarn you can protect yourself from terrorist attacks and other threats. terrorwarn has access to your location and warns you instantly when you are moving into a dangerous area. If you witness a dangerous situation you can send an alert to warn other users who are using the app. terrorwarn does not depend on official state instances like the police, it is also user based and therefore faster than traditional warning systems.
