Just want to share a great app I've discovered.
I've been a lifelong diarist (since 1964). I weathered the transition from hand-writing to composing on the computer, but once blogging and writing on boards like this became an option, I really fell off the wagon with my own personal journal writing.
A little while ago I realized how much I missed it. Writing for others cannot replace writing to yourself as meditation and expression, so I tried to figure out what the barriers were to my losing the consistency and the will to write. I identified two barriers: A) I don't think of it on a daily basis and B) even though opening up my Word document is maybe two steps, it was two steps too many. So I started researching apps.
My research led me to choose Day One. It breaks down the specific barriers I had. First of all, it's a very, very simple app. It's simply a dated page, really. No fancy schmantzy tags, links, video, audio blah blah blah. Just a page, with a motivating quote, if you choose one.
It breaks down Barrier A (reminder) by popping up at the time of day I'm most likely to be able to write. You can set your own time. I've chosen 8am. You can snooze it by an hour or a day, or skip it completely. There's also a little box for a "quick-journalling" option, so you don't have to even press one button to start writing. (Barrier B) You can also password protect your entries.
I know there are a lot of people here who are inclined to journal, or do already--so thought you might be interested
I use it on my Mac, and it's available for Mac and iPhone. It's $10, but I really think it's worth it.
