Namazu Alert

This application serves as an earthquake alert system that sends push notifications. Compatible with Android smartphones, it allows users to access the most up-to-date earthquake data in Japan. While still in the experimental phase, the push notification feature provides users with the latest earthquake information, though it is not guaranteed to notify for every situation. It's important to use this app as a supplementary tool when official information is unavailable. Activating the feature is simple and can be done via Settings. Be aware that all recent earthquake alerts and notifications provided through the app are based on initial findings, which may differ from official data.

Regarding KeepAlive interval, it is recommended to avoid changing the default settings as it could impact push notification delivery and lead to faster battery drain. If your router has specific settings, adjusting the Wi-Fi KeepAlive value to be slightly lower can help conserve battery life.

The app may experience issues with location accuracy, as it estimates the distance between a user's location and the epicenter based on their last recognized location. If using the app for the first time or if GPS-enabled apps have not been used before, current location may not be recognized. It is important to note that positioning can take time and may not be reflected in alerts received.
