Features & Capabilities

The NERV Disaster Prevention app offers comprehensive real-time disaster warnings and weather updates tailored to your current or registered locations. Connected directly to the Japan Meteorological Agency, it delivers the fastest earthquake, tsunami, volcanic eruption, flood, and landslide alerts in Japan. Users can interact with detailed maps displaying cloud cover, typhoon forecasts, earthquake intensity, and more.

Designed for accessibility, the app features clear fonts and color schemes considerate of color blindness. Critical alerts override silent or do-not-disturb modes to ensure immediate attention. The app also supports users through a voluntary Supporters' Club to maintain and improve its services, while committing to strong privacy practices by anonymizing location data and safeguarding user information.

User Reviews

Users praise real-time, detailed earthquake alerts and comprehensive disaster data, especially for travelers in Japan, with an ad-free, clean interface. Major downsides are Japan-only coverage, occasional post-update bugs, and limited customization. Requests include international expansion, more location options, bear-sighting data, and clearer feature labeling.

Pros

Real-time, fast earthquake alerts with countdown and sensor visualization.
In-depth disaster information with radar view, wave height, and time of arrival.
Highly useful for travelers/ foreigners in Japan; essential for staying informed during disasters.
Ad-free, clean, minimal-fuss interface with reliable alerts and radar features.

Cons

Japan-only coverage; cannot switch to or check other countries (Turkey, Philippines, etc.).
Occasional bugs after updates (data retrieval errors) disrupting the home/locational data.
Limited customization (cannot adjust alert thresholds) and restricted location options.
Some reports about inconsistent feature labeling (claims of an earthquake feature that isn’t visible in some cases).

Please bring global support. I would love to be able to use this app in my home country, Türkiye, as a huge fan of both preparedness and the Evangelion Series.
