Day One
Day One is a set of apps for OS X and iOS designed to help you keep a daily journal or diary, with a focus on quick and easy text entry. Synchronisation is via Dropbox; iCloud support is planned.
The Mac version ships with a command line tool, so you can easily automate some of your diary-keeping (adding the day’s tweets and todo list, say) or import content from similar apps.
