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I've realised my review is 2 years out of date. Love the app and the simplicity of it. I'm using it to complement paper and pen journaling. I stuck with it, got a new phone with latest version of Android and the developers have made big strides in providing functionality to match the IOS version. It also continues to get new features. Would definitely recommend now!

The app is great for what I need it for but I need to change to another app due to constant crashing. This happens when ever I'm putting a new entry into a new day I get constant crash warnings and the app becomes frozen and unresponsive. I know this is to do with my phone as I've not had this issue pre changing to a new phone my partner is still having no issues at all. There no updates and I've even uninstalled and reinstalled. (For the developers, for what it's worth, I'm on the Pixel 9 Pro)

Hello! I see you're reviewing this for version 2025.3. Have you tried updating to version 2025.4? Does that help with the crashing you've seen? If it doesn't, we'd love to look into this more with you! Please reach out to us directly. dayone.me/support

It's very straightforward and easy to use, quite customizable and I like the daily prompts too, give me something to think about. I'm just a little annoyed with the general state of the world where every app (or what have you) has to have a premium pay-to-use version. Like what the hell happened, you know.
