My parents have lost most of their hearing and have difficulty communicating.
So I wanted to display text on the tablet.

However, a common method is to use the Internet. It cannot be used in locations where the Internet is not available.

Therefore, I created an app that connects two smartphones using Bluetooth.

It's okay even if you don't have Wifi or LTE. There are no communication charges, so you can use it with confidence.


Pair the two smartphones to connect them via Bluetooth.

① Swipe down while keeping your finger on the screen
②Long press the Bluetooth icon that appears
③Tap [Pair new device].
④Tap the name of the Bluetooth device you want to pair with the device.
⑤Follow the instructions on the screen. (Enter number keys, etc.)


① Start the first smartphone as a server.
② Start the second device as a client. The client selects and connects to the server's smartphone.
③By writing messages, you can send messages to each other.

You can also enter using the keyboard.
Two shortcuts are also available.
Ctrl+W = Write
Ctrl+D = Clear
