memoTalk(Bluetooth WhiteBoard)

You can connect 4 smartphones, and share handwritten notes in real time.
It is like a white board, and you can connect devices by bluetooth.

You can use it for the meeting, or to share images to other people like friends or your children.
You can also save the notes in your gallery.

First you have to select "Parent" or "Child".
If you chose "Parent", you have to wait for other "Child" devices to connect.
The "Child" device needs to scan for the "Parent" device.
If the "Parent" device doesn't appear in the device list, "Parent" device should tap "Discoverable" so the "Child" device could find.
