It is more useful than i thought
SO EASY TO WRITE with circle. And add photo also. When i using other memo apps, i had to tap over than three times. But this app requires only twice. (except steps in camera app)
If i can suggest something to need, i recommend to add widget function like Evernote. More simple than Evernotes pop-up. I think that it is possible with circle.
