Now days smart phones are very affordable, common to people and used in many applications. Thus, implementation of a dedicated mobile app for EEW systems is perhaps the best option that can save lot of money and time to achieve dissemination of earthquake early warning (EEW). This paper presents details of development of a smart phone app for android and iOS operating systems for EEW System currently operational in Uttarakhand, India. This app is freely available on Play Store and App Store with the name of “Uttarakhand Bhookamp Alert”. This app uses Firebase Cloud Messaging (FCM) service for sending earthquake early warning to users. User needs to install the app in their smart phones for receiving early warnings. User’s basic information along with FCM token is saved at the developed warning server in a database during the user registration process, which is being shared with the disaster response authority in case of earthquake to rescue the users if they are stuck. Our app also contains information about the steps needed to be followed on occurrence of an earthquake as well as how to make and find safe places in your house for hiding during occurrence of earthquake.
