Customer Reviews

A solid, cross device journaling experience with good UI

I haven’t updated to 1.10.2 yet nor have I updated my Mac to El Capitan. So I can’t speak to any recent technologic challenges/issues with Day One. What I can speak to is how simple and appealing it is to journal my thoughts across my Mac/IOS devices using Day One. Even though I’m also a huge Evernote user - I much prefer the UI of Day One for journaling my thoughts. It just feels more welcoming to the written word - where Evernote excels in accepting different formats, but with a fairly lackluster visual experience. Especially for writing and recording thoughts over a period of time. The calendar cues, the typography, and the timeline views are all very rewarding.


This app was nice when it first came out, but features promised by the developer and asked for repeatedly by users did not make it despite several updates. The most important missing features are encryption and full PDF support. There are now several alternatives to Day One on the app store that support these features. Unfortunately, instead of spending some effort an energy to add the requested features, the developers put their time an energy into developing their own sync service which is not needed since the app works fine with iCloud. Day One, once the premier diary and note taking application, has become irrelevant. I started copying all my entries into the improved Notes app, and when I am done I am deleting Day One from all my computers and iOS devices!

Best Journaling App Got Even Better

This latest update not only offer splitview support for the latest Mac OS X El Capitan, which is cool, but what I like the most is the updated/tweaked/corrected fullscreen mode. The fact that when you go fullscreen with this version of the app it will actually expand to fit the entire screen, whereas in the past there was untilized screen space on either side, made the writing platform look expansive and feel more inviting. Great update. Looking forward to Day One 2.0.
