content: i use this app all the time i looked into alternatives but this one was the best you can find if you dont wanna spend any money honestly the only problem i had with it was having to create a Microsoft account to use it but other than that it does its job a walking notes. would be cool if you had more customization options though there are some symbols that i use in certain classes but the only way to do a custom symbol right now is too draw it every time or import it from somewhere else.
