This is one of my favorite open source projects! Also, if you're looking to get better at markdown, this is the app to do it. The free sync is fantastic - because it integrates with dropbox, and because most of what you're syncing is just text, you can use this for quite a while before reaching the dropbox free-tier limit. I can keep a journal at work and have it sync to my phone, personal workstation, and other devices. It's really quick and most importantly - a decent community and still actively developed!
