    I live in Day One

    I have been using Day One since it was in beta. I am a writer and digital content specialist so I do a lot of writing. Day One has grown in capability and beauty since its inception -- I use it more and more everyday.

    To be frank, I tried to use EverNote but found to cumbersome and a bit much. For my mind, Day One provided the perfect palelette for me to sit down and write anything -- the tag it, or easily move it to another journal. It allows up to 10 journals, one of which I have synced to my Instagram, as I like to keep a record of what I post there.

    If you are writing daily, doing Morning Pages, if you blog and need a place to work on drafts, Day One's set up is so easy. It syncs over the cloud to your phone (I'm on Apple products, recognizes voice to text smoothly and allows images to be easily drag and dropped.

    The interface with tagging could be slightly more intuitive but the team is constantly doing updates and I am sure that will be worked out soon.

    I love it and recommend it to anyone writing.

The 8 best journal apps of 2022
Perhaps Day One's best feature is the ability to customize multiple reminders. Most other journal apps only send you one reminder during the day. But with Day One, you can get prompted to write, say, when you start the day, at lunchtime, and then at the end of your workday to keep track of your activities and thoughts throughout the day.
