There's something in your mind and you need to write it down, but (Yes, there is a 'but') you're away from your PC. I started a search for a simple note-taking app on the PlayStore with markdown support. I tested a few and found a winner:
Epsilon Notes
Playstore link: Here
It's cool because it supports (as the main feature) markdown. Here are some screenshots from my device:
It's pretty Cool if you ask me. do you see the bottom toolbox? You can use every element of the markdown and, of course, you can get the result when reading the note.
Do you save drafts for your Steemit daily blogging? If yes, do you use an app or the classic paper & pen?
I started with the mission: No paper consumption. I will talk about it later on.
May the force be with you
