@big_puppy Conciliate note taking and task manager can be quiet touchy. It depends on what you really want, the software you like and how you want to do with it also if you want something working on Mac only or with Mac / PC. Here are a few option and my advices. First ask your self what is the most important for me : Task or notes ?
- You could use
Omnifocus it is a cross platform you can use it online but it Mac only. It is great for GTD. It's learning curve mais be touchy at the beginning but it can be set simply. Take the pro version for getting perspectives.
- To do ist is it competitor. Very well done, I'd a monthly/ yearly paid you it works very well. It is affordable.
Both of the solution can have link to another software
- Note taking and taking manager could be notion. I hate it but it is free. Its learning curve is difficult. It takes time. Notion can do everything. It is also an online solution like todoist.
- Nirvana is a GTD friendly app. Perfect for GTD better than anyone for me but it miss the power of perspective (= sorting informations)
- Evernote can do the job but I hate it and it is too expensive. It is imagined for taking note. Also think about what will I do If I want to use another software and use my previous datas ? Evernote accept only per file not by folders. It client support is awful sadly. Evernote used to be very good but it is for me far away from some of his competitors.
- Prefer it
Obsidian. Much better. Free, sync (you could use iCloud) it .md files eg .txt it is the perfect system for note taking and can work for GTD if you know how to make it. There are so good article on the web and may be here I think but I dont know where. There is a paid version but it is for jeeks.
My own way, as I explained somewhere else I use Omnifocus. I know it by heart. It is very powerfull. And for note taking I use apple note. I make a link from one to the other it works very well.
If I could not use Omnifocus, perhaps I may choose todoist. They have made so much progress and are so good for a good price that it worth it however using it on day to day is more complex than using Omnifocus. So a very good solution could be Obsidian. Obsidian is an astonish software. It is a not taking app but you can make link and document everywhere inside and outside the app. I love it. So I would probably chose it instead of Todo ist except it they add new function I need.
Hope that's help your choice and be back to us to explain what you choose and why and how is it going...
