Simpleaf is a very simple and surprisingly efficient handwriting memo app.
For example, when you want to make a note while web browsing or making phone calls, you simply swipe down the status bar and launch Simpleaf.(*1)
You can also make a note, at the same time you are looking at the screen by making Simpleaf transparent.
Written memos can be transmitted to mail apps or Evernote.
(Traffic can be saved by specifying an image size and format.)
(*1)Launching from the status bar doesn't work if the app was installed on the SD card.
