One of my favorite and most used apps, Day One, is on sale now through December 26 for only 99 cents. It’s normal price is $4.99.

If you’ve been holding out because you think five bucks is too much to spend on any app, here’s your chance. But, really, an app that brings value to your life is easily worth a few bucks, especially considering the silly things we all waste money on that bring no value in return.

Day One, of course, is a journal app, and it’s lovely. It reduced the friction that kept me from ever sticking to a journal habit and actually made it fun to chronicle my life. I treat it like my own private Twitter, that no one sees but me.

As I’ve been looking back over the year recently, Day One has provided a delightful way to remember what has happened and what has mattered most.

Day One is just one of many apps that are on sale right now. Here’s a great list of the great deals from MacStories. I also love Tweetbot, the best Twitter client, and SolarWalk, a gorgeous exploration of the solar system.
