About this app

Day One is the journal app that reinvented journaling. Completely private, cross-platform, and designed to never fill up, Day One is designed to let you capture your life as you live it. Use Day One as a daily journal, personal diary, note taking app, travel log, or gratitude journal.

“Day One creates something so rare it feels almost sacred: A completely private digital space.” – New York Times

“Day One makes keeping a journal delightfully easy.” – Wired

“It’s perfect! Does what it says on the box. I was able to import my stuff from another (pricey) journal so that I didn’t lose those entries. It’s easy to add multiple entries to a day and to keep pictures. And it’s lockable, keeping private thoughts protected. I will happily use Day One for years.” – Day One user

I have been using this app daily for over a year now and have had no problems with it. A couple of small improvements would be that in the most recent update the Tags section was removed and now there is no longer a way to access that menu easily which is a shame because I liked being able to find entries based on it's tags and there is also the option for a banner photo on the app which is lovely but there is a transparent black filter on it which makes photos hard to see but that's nitpicking

I have lowered my original review due to an ongoing issue where the app and desktop client do not refresh properly. I have lost hours of typed content that is typed in to only go back later to find that when I opened my phone to double check it had copied over it instead Refreshes and erases what I just typed. it's happened considerably enough now that I will probably be looking for a new platform.

I’ve used Day One for a long time—it's clean, simple, ad-free, and distraction-free. No useless features, just pure journaling power. I can instantly write thoughts or reflections without hassle. Huge thanks for keeping PDF export free—being able to save beautiful offline copies with one click is priceless. A perfect journaling app. 5 stars!
