really good markdown editor, overwhelming amount of community plugins, all data's local and stored in plaintext. app itself is free, easy syncing option is the $4/month (with afew other nice to haves) though there are ways to do it for free (syncthing, but that's changing with the ST team not supporting andriod anymore and apple is weird too).

I've now been using it for ~3 years and I do everything in it. wonderful, wondeful tool
