I've experimented with many note taking apps, but this one is my favorite. The notes sync across all my devices using iCloud. The app is beautiful and minimalist, getting out of the way so I can focus on the task at hand. Oh, and it uses markdown under the hood so formatting is a breeze for my many, many bulleted lists. I like the app so much I gladly pay $1 a month for the pro features.
OMG, Bear is a game changer! Just Downloaded. I use my IOs notes all the time and although it captures my thoughts, it somewhat clunky. Love this!
