NERV Disaster Prevention

iPhone / Météo

The NERV Disaster Prevention App is a smartphone service that delivers earthquake, tsunami, volcanic eruption and emergency warnings, as well as provides weather-related disaster prevention information for flooding and landslides, optimised based on the user's current and registered locations.

The app was developed to help people living in or visiting an area where damage is expected to occur, to accurately assess the situation and make quick decisions and actions.

With information received directly through a leased line connected to the Japan Meteorological Agency, our proprietary technology enables the fastest information distribution in Japan.


▼　All the information you need, in one app

Get a wide range of disaster prevention information, including weather and typhoon forecasts, rain radar, earthquake, tsunami and volcanic eruption alerts, emergency weather warnings and landslide information, river information, and heavy rain risk notifications.

By interacting with the map on the screen, you can zoom in on your location or pan across the country and see the cloud cover, typhoon forecast areas, tsunami warning areas, or the scale and intensity of an earthquake.


①　Providing users with the most appropriate disaster information

The home screen displays the information you need at the time and place you need it. When there’s an earthquake, the home screen will show you the latest information. If another type of warning or alert is issued while the earthquake is active, the app will sort them depending on the type, elapsed time and urgency, so you’ll always have the most important information at your fingertips.


②　Push Notifications for Important Information

We send out different types of notifications depending on the device’s location, the type of information and level of urgency. If the information is not urgent, we send a silent notification as not to disturb the user. For more urgent situations where a disaster is time-sensitive, a ‘Critical Alert’ alerts the user to an imminent danger. Notifications like Earthquake Early Warnings (Alert level) and Tsunami Warnings will be forced to sound, even if the device is in Silent or Do Not Disturb modes.

Note: Critical Alerts will only be sent to users in the target area of the most urgent types of disasters. Users who have registered their location but are not in the target area will instead receive a normal notification.

※ In order to receive Critical Alerts, you need to set your location permissions to “Always Allow” and have Background App Refresh turned on. If you don’t want Critical Alerts, you can disable them from Settings.


③　Barrier-Free Design

We paid close attention when designing the app to ensure our information is accessible to everyone. We put a focus on accessibility, with colour schemes that are easy to distinguish for people with colour blindness, and use a font with large, clear letters so long bodies of text are easy to read.


▼　Supporters’ Club (In-App Purchase)

In order to keep doing what we do, we’re looking for supporters to help us cover the development and operational costs of the app. The Supporters’ Club is a voluntary membership scheme for those who want to give back to the NERV Disaster Prevention app, by contributing to its development with a monthly fee.

You can find out more information about the Supporters’ Club on our website.

Gehirn Inc. is an information security company. The security and privacy of our users is our highest priority. We take great care not to collect excessive amounts of information about our users through this application.

Your exact location is never known to us; all location information is first converted to an area code used by everyone in that area (like a zip code). The server also doesn’t store past area codes, so your movements cannot be tracked.

Quoi de neuf dans la dernière version ?

- Updated the app's internal architecture
- Membership information for the Supporters' Club is now displayed in the Home tab

◆ Internal Architecture Update
We've updated parts of the app's internal structure, components and runtime engine to their latest versions. Though you may not notice a difference in your everyday use, these kinds of updates are necessary to improve support for the latest operating systems, and to keep the app running smoothly. Speed and performance have also been optimised!

◆ Supporters' Club Membership Information
The app has now surpassed 8 million downloads! We are truly grateful that so many people use the NERV Disaster Prevention app in their everyday lives.
As the number of users grows, so do costs related to data processing and network usage. This makes support from our Supporters' Club members all the more important.
For this reason, we've started displaying membership information at the top of the Home screen for users who have not yet joined the Supporters' Club. This banner will not be shown to active Supporters' Club members.

◆ Dev Team Updates
This month, we've spent a significant amount of time handling and responding to hearings and research requests from various central government ministries and agencies. Although we handle these hearings free of charge, we do so because we hope to contribute to improving disaster preparedness nationwide – not just for ourselves. (Though giving it our all tends to bring in even more requests...)

These efforts are only possible thanks to the support of our Supporters' Club members. We greatly appreciate your ongoing support.
