Insanely confusing but... awesome

As a medical student, I am constantly searching for the "best app" for note taking. This app is able to do so much more than any other app I have ever used and yet, it's not well known. Tbh, I think this is likely due to the complete and utter lack of instruction. I consider myself well above average when it comes to computer competency and this app still took me FOREVER to understand. They have a video series explaining some features but it just barely scrapes the surface of what this app can do. It is a PDF editor, mind-mapping tool, that can generate flashcards (that can be added directly to anki) & perform screen grabs of anything, use OCR to convert to text, and it can even perform research (google, medscape, etc.)... this app is incredible but it is incredibly complex to use. I would rate it lower for that simple fact but I want others to know its potential and hopefully persuade the developers to address their one flaw and produce a legitimate instructions manual.

Useful tool for annotating and connecting ideas

What I love about this app (and I use it on my Mac, iPad, and iPhone - though you have to buy two copies, one for MacOS and one for IOS) is the MindMap.

Often I work on projects that require brining together information from a lot of different sources. Additionally, theres a lot of different ideas/topics/information that is connected or related in some way and I never had a way of connecting that in my head. The MindMap lets you (essentially) build a web a knowledge. But because you can connect the source to the note, you can also review that information should you need too. Plus, the tools for adding information to the MindMap are easy to use and effective.

I also really like the tools for annotating on MacOS. Specifically, letting me make the lines for the highlighter and pen straight makes it easy to use a trackpad.

Overall this app has really helped me orginize and connect vast amounts of information and quickly became an app I use everyday.

NO manual

Downloaded the app and it looks like something I could really use. Unfortunately, I can not figure out how to use it and I am fairly computer savy. There is no manual as many in the forum have complained about for over a year. No developer should ever release an app without a manual available. There is no help on the website other than videos that go at a breakneck pace so you can't even follow them. I don't like watching videos to learn. I need to be able to read directions. The developers apparently speak Mandarin and have not made an English manual and the translations of what help is there is very confusing. I am not spending hours combing forums to figure out how to even get started. A free trial is no good if it takes longer than 14 days to even get started. I got frustrated and have deleted the app. This isn't normal for me since I take the time to master the apps I use including other apps with steep learning curves like Scrivener. If there is no manual you don't get my money, which is too bad because this looks like a powerful and useful app. Bu I won't ever use it because I need a workflow now.
