MyScript Smart Note's two main features let you write (using your finger) or draw. With the first option, you have several added features to make writing on your virtual notepad much easier. Meanwhile, drawing offers you several different features which are more geared towards creating sketches or small works of art.
MyScript Smart Note has undo and redo buttons which you can use as many times as you need. Plus, you can select an isolated stroke and freely modify it: you can move it, stretch it, enlarge it, make it smaller, etc.
Other options include importing images from your gallery onto any page on your notepad, recognition of over fifty different languages, or the option of directly seeing definitions of words.
MyScript Smart Note is a great virtual notepad for Android which, even in its free version, offers more than enough features to satisfy even the most demanding users.
