The app tries to use bluetooth to spread the message to any location you pass by, as long as someone there has the software installed on his phone, your message should be delivered to him, the message is in store-and-forward mode, so even if your phone is turned off or Damaged, the message you have sent will continue to spread.
Our app is currently the only app that does not need to be connected to any server for authorization to use. From the first installation and opening of the app to each subsequent use, it does not require an Internet connection.
That is to say, your mobile phone can use the app without inserting a sim card or connecting to wifi, as long as you turn on the bluetooth. What needs to be explained here is that the location permission is required by the Bluetooth device to search for nearby Bluetooth devices on Android devices lower than version 12, and does not actually obtain your location. You can rest assured here.
At present, it supports the spread of text, pictures and voices. Text is relatively stable, but pictures and voices are not very stable. We will continue to adjust it in the future to make it stable.
Please note that by default, only when the app is opened will the surrounding devices be searched and connected, but as long as you manually grant the permission to allow location at any time in the permission settings of the app, you can unlock the phone without taking out your phone. In this case, it will automatically search and connect surrounding devices in the background. We will enable this feature by default for the latest Android devices at a later date.

The first page of the software is a welcome message that briefly introduces the function and purpose of the software.Please click next

On the second page, you need to choose which way to connect the software with surrounding devices, we provide 2 ways, bluetooth and wifi

We recommend that you select the Bluetooth method and give the location permission, which is a feature of this software, and the use of Bluetooth allows free flow of messages. Location permission does not actually get your location, Android devices below version 12 require location permission to allow the Bluetooth function to scan and connect to surrounding devices. The software cannot be used without giving the location permission. Please understand.

The wifi method allows you to exchange messages with devices in the same wifi environment. This method is more stable and faster than the bluetooth method, but we do not recommend you to use this method only, because most of the time you and the need The communicating devices are not in the same wifi environment.

Note that if neither bluetooth nor wifi is selected, your software will not be able to search for and connect to and communicate with surrounding devices. Urgent messages cannot be delivered either.

On the third page of the software, you need to choose a way to create a user, you have 4 ways to create a user, if you use the software for the first time, please find the bluetooth physical address on your device first, it is usually written in System Settings - System - About - Hardware, the Bluetooth address is roughly in the following form:
76:f7:1c:1d:71:d2
After filling in the Bluetooth address, click Create New Profile to get started

If you previously saved the last used configuration file in a QR code, clipboard, or NFC tag, please use the last three methods to import your configuration file. If your profile has a password set, be sure to remember your password. Otherwise your configuration file cannot be imported.

The first page is the user page, if there is another user nearby, you will be automatically connected to that user and the user address book will be synced to your device. Please note that the address book here is the address book of the app, not the phone address book in your phone.

Public messages on devices near you, those that are not expired, will also be synced to you.
