About this app

[What is Kotobubble]
This is an AR application that allows you to write handwritten messages and pictures in the air and send them to each other.
Users can share a freely created talk space (AR space) with each other and communicate by handwriting within that space.
Enjoy handwriting freely on an infinite canvas using length, width, and depth.

[Origin of the name Kotobubble]
Messages written in the air become "bubbles" and float in the air.
When you tap the floating bubble, a handwritten message will appear one stroke at a time.
It's a new feeling, as if the other person is writing a message right in front of you.

[What kind of scenes do you use it for? ]
・When you want to send a warm message instead of a chat or letter
・When you want to easily send a handwritten message to someone
・When you want to freely enjoy handwriting on an infinite canvas
