The writing app is an expert in handwritten comments. It uses natural handwriting, which is easy to operate, easy to record and explain the process, and the annotations are vivid. It has not only text annotations, but also synchronous voice. Talking about app is a good assistant for knowledge explanation, training, technical exchange, viewpoint transmission and handwritten notes.
It is not recommended to take notes directly on the mobile phone, which is easy to distract attention. It is better to use a tablet, laptop or pen to simply record in class and sort it out after class than to use a mobile phone. Of course, if you are taking photos or recording, using a mobile phone is also good. You can try the notes or memos that come with your mobile phone first to see if they are enough. If you want to use additional applications, here are a few for reference only: Iflytek's notes, Youdao's notes, OneNote, Zhou Xiao's notes and Meizu's notes.
