Size of canvas is unlimited - even if the canvas was not enough for drawing, you can continue drawing immediately after scrolling. You are not restricted to a narrow screen of smartphone!
(Mugen is the meaning of "infinity" in Japanese.)
Many times you can undo the operation. Because the undo history is stored on the storage with note, you can return to the previous state at any time.
MugenNote has a variety of drawing functions: pen with alpha, pattern brush, text, paste image, etc.
In addition, you can post on twitter/facebook directly.
(Exporting .JPG file functionality is only supported on paid version)
To write down notes and sketches, and record your ideas every day, please try the MugenNote.
* So as not to use too much storage capacity, the maximum undo count is limited 20 times after installation. You can change this settings on Settings menu.
* About paid version:
A paid version is available as "MugenNote".
After you update to the paid version from the free version, simply re-install it.
