In recent years, indiscriminate robberies and burglaries have been increasing.

What would you do if a stranger was nearby in the middle of the night?

Calling out for help might alert the attacker.

You might not have time to operate your smartphone or unlock it.

That's where "OneTAP SMS" comes in.

【What this app can do】

■ Send Mass SMS with One Tap
Simply launch the app and tap the red SOS button once to send a pre-set message via SMS to all your registered family, relatives, and close friends.

■ Automatic Location Attachment
In urgent situations, you need to communicate your location.

This app automatically obtains your current location via GPS when the SOS button is pressed and incorporates it into the message with a link to Google Maps.

The recipient can see your location on a map simply by tapping the link.

■ Proxy Reporting by the Recipient
Family members or others who receive the SMS can use the location information in the message to call the police (110) on your behalf and request help.
This allows for appropriate assistance even if the person is unable to speak.

■ Up to 10 Contacts Can Be Registered
Up to 10 contacts can be registered.
You can also register them by directly selecting from your address book, eliminating the need for tedious manual entry.

■ Basic Information is Automatically Sent
Personal identification information such as name, address, phone number, date of birth, and gender is automatically included in the emergency SMS.
This saves recipients and the police the trouble of verifying identity, leading to a quicker response.

【How to Use】

1. Launch the app and register your basic information (name, address, phone number, etc.).
2. Register up to 10 emergency contacts (you can also select from your address book).
3. In an emergency, launch the app and tap the red SOS button.
4. The app will automatically acquire GPS information and send an SMS to all registered contacts.

* On iOS, after one tap, the SMS app will launch and the message will be displayed with the content automatically filled in. You will need to tap the "Send" button once at the end.

* On Android, the message will be sent automatically with a single button tap.

【Privacy Considerations】

All personal information is stored only on your device and is never sent to external servers.

We do not use advertising or usage analysis tools.

【Caution】

⚠️ The phone number you register must be capable of receiving SMS (Short Messages).

⚠️ Please be careful not to send prank messages or messages to the wrong recipient. This may cause trouble for the recipient or their family.

[About OneTAP 110]

We have also developed the OneTAP 110 app (direct SMS sending to 110), but the function of sending SMS to 110 is a special feature available only to telecommunications carriers and cannot be implemented in general apps.

If you are a telecommunications carrier and are interested in this system, please contact us.

We hope this app will serve as a safeguard for everyone and help prevent unforeseen circumstances.
