Not sure why what app being used is relevant. Plain text is all we need to write anything like this. You could use Markdown if you must (and must you?), but whether you use VIM or emacs or sublime slime or something else, two things are clear:

You type in plain text (just like I'm doing here in this comments box) and jot down notes. Save it an ongoing text file (probably called 'ideas.txt' or you could separate them into 'personal_ideas.txt' and 'business_ideas.txt' and 'new_relationship_ideas.txt' (lol) if you need, and place all that 'org' stuff in a folder that auto-syncs to some service somewhere if you need cloud backup (dropbox, iCloud, gdocs, etc).

Standard iOS Notes app is fine if you are all in the Mac/iOS space routinely.

The only thing I do in terms of 'formatting' is to put bigger ideas in all caps and then indent (it's a tab!) for sub-notes and maybe put an asterisk if I'm feeling bulletproof.

So, like this:

from business_ideas.txt

* increase Twitter to 180 characters * publish corporate drone-like rants on LinkedIn * command-line movie time tool * dog walking service combined with GoPro/Vine channel for owners to watch 'best of' clips * invent a new "to-do" app and try to monetize it since text files haven't worked in 30 years * See if WordStar is for sale and revamp it for the Mac with lots of shiny glossy new icons * MOSQUITO FARM order breeds online build security fence to hide farm from nosy neighbors what about a super-mosquito cross-bred with a hornet? sell to labs who need well-trained mosquitoes for zika testing * refurbish old consignment shop as an "eBay shop" * frozen yogurt, but only for pre-teen girls in a "safe" environment (no boys allowed) and only in girl-like colors, but where we teach them coding, laser tag, and play songs from the movie 'Frozen' all day long. Name: Frozen Yog-Her? * record online python coding tutorial for beginners since there is not much available now
