Usage Steps;

1.When the application is first opened, it first directs you to the emergency contact adding page. Here, the emergency contact's name, surname, and phone number are added. After adding the contact, it is saved through the "Contact Added" popup. Then, with a single click, it is possible to edit it, with a long press, it is possible to delete it (with user approval). Adding one contact is mandatory. (The data stored in the white rectangle is personal information). Example for Step 1:

Add Emergency People Name&Surname

Add Emergency People Phone Number

Edit Emergency People Name&Surname And Phone Number

2.Camera permission is for flash warning (visually impaired) and SMS permission is for sending user-approved SMS to emergency contact during an earthquake. Example for Step 2:

Check Camera Permissions For Flash Alarm

Check SMS Permissions For Send Emergency People Alerted Earthquake!

3.After adding an emergency contact, we return to the main screen of the application with the back button. Here, we are greeted by Google Maps and a list below it. The red markers on the map show the earthquake, the green marker shows the user's location. Data from JMA (Japan Meteorology Agency) is listed, and then we can print it if we want by selecting an item from the list (Wi-Fi print).

4.Finally, when an earthquake is detected, JMA data and the phone's accelerometer are used. First, the earthquake condition is checked. If it's not, it's perceived as a false alarm and isn't triggered. However, if it's >4.0, it first examines the JMA data to see if there's been an earthquake in the area that's experienced it before. If not, it detects it as a new earthquake and displays a warning message to the user. It provides earthquake information such as intensity, magnitude, and depth. Three options are available: 1. Mirror Screen (so you can follow along with your family on your TV). 2. Print (printing details as evidence for emergency services). 3. 119 (Japan Emergency Line) is user-approved. Meanwhile, if the battery is <20%, the "I'm safe" + location information is sent to the emergency contact. In case you're offline, the data is stored in the cache while you're online, keeping you up-to-date when offline.

Automatically opens the SMS screen of the emergency contact when an earthquake is detected (user approved)

=4.0mW When it detects an earthquake, it works as a combination of flash + vibration + alarm and when you return to the application, the earthquake information on the screen is displayed from left to right as "Reflect on Screen","Print","Call 119"
