GoodNotes has been around for a while now and in the beginning I was not as convinced about the app. Recently I gave GoodNotes a try and it convinced me so much, that I dropped OneNote.
First of all GoodNotes is perfect in organizing your notes which are stored in a notebook. These notebooks belong to a specific category which gives you a really clean overview. After creating a new notebook you can choose from a variety of cover sheets which gives every topic its own style.
Afterwards you add pages and start writing like on paper.
Additionally, there is one really useful button in the top bar which enables object/shape recognition which works amazingly good. So when you draw a circle or a rectangle and many more it recognizes it and draws it with straight lines which leads to a very clean look as there is no rough line. Furthermore, GoodNotes has the ability to import images, create textfields and make bookmarks.
Next, there is also a search feature which works stunningly well for handwriting. My handwriting is really not the most beautiful and it detects almost every word I searched for. One other beneficial aspect is the wide variety of sync services you can choose from like iCloud, Dropbox, Box, Google Drive & OneDrive. I have only tried the iCloud sync which never made any problems.
