防災・防犯ブザー・電話　緊急SOS

"Emergency SOS for Disaster Prevention, Crime Prevention, and Phone Calls" is an emergency security app that sounds a loud buzzer with one tap in an emergency and easily sends SMS and phone calls to pre-registered contacts.

The app is completely free of advertising and in-app purchases, and runs entirely on the device.
No communication or data is sent to external servers.

Main Features

Buzzer Function: Alerts those around you to danger with a loud alarm.
A flashing light (on/off switchable) adds a visual appeal.

Location Display: Automatically obtains your current location from GPS and displays it on the screen.
In an emergency, you can automatically insert your address into the SMS text.

SMS Sending Assistance: Creates a message to registered contacts with "Emergency SOS" and your location information.
Since the actual sending is user-initiated, there is no risk of sending to the wrong person.

Phone Call Assistance: Go to the call screen with one tap on "110" or a registered number.
The phone book app opens automatically, making it easy to use even for beginners.

are never sent to the cloud or a server.

This app contains no ads and does not track or collect data for revenue purposes.

User personal information, location information, or phone number will not be sent to third parties, including the developer.

The developer is not responsible for any damage or issues arising from the use of the app.
