When I first saw this app on the MAS or Crap App $tore I thought it was a crap app like many over there.
A few month later I discovered it on a friend's computer and tried it: I like the unobtrusive quick entry mode with short cut, Markdown support and its searching capability. I miss tags but I saw on your website that you are going to introduce it (as well as photo support) in a next release then I'm already tagging the entry a I'm making.

I bought your app because I was able to try it before and only because of this. I've also discovered later in Brett Terpstra' blog a script who put automatically the @done from TaskPaper in Day One, how to log from the terminal and even (I don't remember where) to make entry from some other apps. I use Day One to remember what I've done during the day (scripts, mails, etc). Very practical for me.

I wonder why you don't provide a trial and I understand that people don't want to buy your app without a demo. No demo no sale.

Doesn't actually sync via iCloud until you go to the prefs and click on the sync tab. Doing this somehow makes the sync happen. Might as well have a sync button instead. Which defeats the point of iCloud.

Inspirer, Amazing and Easy to use.

DayOne is made to inspirer you to write your daily thoughts or just your daily to do list using a simple and gorgeous interface. DayOne lets you created reminders that will pop up during the day so you don't forget any of your things to do or just your thoughts. It also allows you to set a password to guard access.

So the true is that I've never been a person who write his daily thoughts on a Journal, nevertheless I decided to give it a try and since the past two weeks that I been using it I start enjoying it a lot. Now I am thinking that writing on a Journal is like making a recording of your days and put it on a "Time Capsule," where you can go back and see what happen that day, month or year in your life. DayOne is made for all kind of people weather you are proactive or just boring. LOL

Looking forward for the next features coming like encryption, Full Screen writing mode and iCloud Sync.

Day One was built exclusively for Mac OS X, and it shows.

Made me keep a journal for the first time in my life. Great interface (though I'd keep the star yellow), light-weight, syncs, stable and, as I said, makes me keep a journal. Also, very responsive developer which gives me high confidence for the future, such as the planned inclusion of photos.

Great app - highly recommended!

I was looking for a minimalist journaling solution. A simple yet elegant interface, nothing feature-loaded enough to bring on a migraine. Just a friendly place where I could type a line or two, maybe a paragraph, maybe more. A passing thought. Whatever.
For a while, I tried all sorts of journaling apps. Among them, the ones I liked most were:
>Osciroi, an original newcomer (with a tagging option), but its editing interface felt cumbersome to me.
>CallitADay, an amazing, elegant diary/journal/blogging application that I stumbled upon, with a unique image-handling feature that I found nowhere else. But still the app felt a bit too much for my needs.
And there were others, more-or-less heavy in the bells-and-whistles department. There was plenty to choose from, but nothing didn't quite fit. I was getting desperate...
And then, suddenly, there it was...in the Mac App Store, of all places:
DAY ONE.
Lightweight. Elegant. Minimal. Freaking love at first sight.
The bookmark-like icon sits unobtrusively in the menu bar, but you can opt not to display it. I'm a menu-bar chick, though, so the icon stays. If that write-now urge hits hard, I click the icon, and the user interface pops up: a clean, fresh gray/blue/white.
I type. I save. No formatting. No images. That's it.
If you want to see former journal entries, from the main user interface click "Open Journal", then "Days".
You can edit old entries.
You can star an entry.
You can enable/disable reminders (frequency, start-time, end-time). I like the reminder feature, keeps procrastination at bay.
You can sync with Dropbox (I do).
You can choose to launch at login (I don't. Outside of few essential apps, I prefer not to launch anything at login unless I really, REALLY have to. Or unless someone has me at the wrong end of a Remi 870. But I digress...).
To wrap it up: if you're looking for a minimalist, aesthetic, no muss, no fuss journaling/diary app, one that would actually make you want to write, I believe you've found your perfect match. It's called Day One.

How do you print either part or all of a journal?
