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

Excellent with one exception: you cannot search inside a particular note. Here's how Day One search works - it returns a list of notes that contain your search term. You cannot search INSIDE a note using the Day One app. This is a huge deficiency. To get around this, use your PC to open Day One on the web. However, this does not work from your mobile device. If you try to use a web browser to access the Day One website you are redirected to the app. Bummer.

Concept is fantastic. Love the Windows 11 app (thank you!). But...hasn't been working properly. Using app on Android (Samsung Galaxy S10) & Windows 11. Mobile app keeps auto-closing on me. I use windows app to enter text w/keyboard, then wait & open app on mobile to add pics and vid. Please fix. Disappointed bc I paid for the year and can't use it as was promised. Thanks for the update - will update app as soon as available. Thanks for addressing.

I've been using this for journaling as recommended by a therapist. It works well, I appreciate being able to have multiple journals. However, I keep sync off intentionally, but after a while of it being off, it randomly turned itself back on. I don't appreciate being forced to sync, especially without notice that it was turned back on. I don't wish to backup my entries.
