Day One has been the default journaling app for Apple users for over a decade. It has won Apple Design and App of the Year awards, it encrypts entries end to end, and it runs almost everywhere. But the free plan is limited to one device and one photo per entry, and syncing between your Mac and iPhone now means a Silver subscription at $49.99/year, or Gold at $74.99/year if you want its AI features.

That has more people looking around, and the timing is good: since macOS Tahoe 26, Apple's own Journal app runs on the Mac. Apple Journal, Diarium, Journey, and Obsidian each replace Day One in a different way: free and built in, one-time purchase, cross-platform subscription, or plain Markdown files you own.

This guide compares them on sync, privacy, platforms, and pricing, so you can pick the one that fits how you actually journal.

Quick Verdict

Choose Apple Journal if you only use Apple devices and want a free, private journal that syncs through iCloud with no setup.

Choose Diarium if you want to stop paying a subscription. Pro is a one-time purchase per platform, and it syncs through your own cloud storage.

Choose Journey if you need the widest platform coverage, including Windows, Android, Linux, and the web, and like guided coaching programs.

Choose Obsidian if you want your journal as plain Markdown files that sit next to your notes and will open in any editor decades from now.

Stay with Day One if you rely on its polish, shared journals, printed books, or years of existing entries, and the subscription doesn't bother you.

Feature Comparison

Day One: The Benchmark

Before switching, it's worth being clear about what you'd give up. Day One offers unlimited journals, templates, daily prompts, "On This Day" memories, streaks, and end-to-end encryption on every plan, including the free one. Paid plans add up to 30 photos or videos per entry, sync across unlimited devices, audio recordings with transcription, and integrations. Gold adds a guided "Daily Chat," AI summaries and prompts, and image generation. It also has shared journals and a printed-book service.

The free Basic plan works on a single device, so Mac and iPhone together require Silver at $49.99/year. Day One is annual-only, with a one-month free trial. If you're leaving, export your entries first; Day One supports data export on its official site.

Apple Journal

Apple Journal launched on iPhone in 2023 and arrived on iPad and Mac with the 26 releases. On the Mac it gets a two-panel layout suited to a bigger screen, and it syncs through iCloud, where entries are end-to-end encrypted. You can lock it with Touch ID or a passcode, create several separate journals, attach photos, audio, drawings, music, and locations, set writing reminders, and browse entries on a map. Apple's user guide also covers printing and exporting.

The limits are real, though. Journal only exists on Apple devices, so it's a dead end if you might ever use Windows or Android. The context-aware journaling suggestions built from your photos, workouts, and places are an iPhone feature, not a Mac one. And there's no templates library, AI, or integrations of the kind Day One offers.

It's free and already on every Mac running macOS Tahoe 26 or later.

Choose Apple Journal if you're all-in on Apple hardware and want Day One's core promise (a private, synced journal) without paying for it.

Diarium

Diarium is the pick for people who are tired of subscriptions. The app is free, and Diarium Pro is a one-time purchase per platform: $14.99 on the Mac App Store. A 7-day Pro trial starts when you install it.

Its standout feature is automatically pulling in the context of your day: weather, photos from your camera roll, calendar appointments, fitness data from services such as Fitbit, Google Fit, and Strava, and some social posts. That makes it good for people who want a daily log without writing much. It requires no account, keeps entries on your device by default, and can lock with a password, PIN, or biometrics.

Sync works through storage you already have: iCloud, OneDrive, Google Drive, Dropbox, or WebDAV. That keeps your journal out of a vendor's cloud, but Cloud Sync requires Pro on each platform you use, so a Mac plus an iPhone means two purchases. Diarium doesn't advertise end-to-end encryption, so your privacy depends on the cloud storage you choose.

Choose Diarium if you want to pay once, own your sync, and let the app fill in the details of each day for you.

Journey

Journey is the most cross-platform option here. It runs on Mac, iPhone, iPad, Android, Windows, Linux, Chrome OS, and the web, so it suits anyone who switches between ecosystems or wants a journal that works on a work PC too.

It has end-to-end encryption, passcode and biometric locks, mood tracking, templates, more than 60 guided coaching programs, shared journals, and export to formats including DOCX and ePUB. The membership adds cross-platform sync, 10 GB of cloud storage, and Odyssey, its AI journal assistant. Journey Cloud Sync is also being released as an open-source, self-hostable server, with a Docker image available.

Journey has a free version you can use indefinitely, but sync and most extras need a membership. In the US App Store the membership is $6.99/month or $49.99/year, and there's a $199 lifetime option. The Mac App Store version requires macOS 15.6 or later.

Choose Journey if you use more than one operating system, or like structured coaching programs to keep a habit going.

Obsidian

Obsidian isn't a journaling app, but many people use it as one. Its built-in Daily Notes plugin creates one note per day from a template, and every entry is a plain Markdown file in a folder on your Mac. You can link entries to projects, people, and ideas, search everything together, and open the files in any text editor if Obsidian ever disappears.

The app is free with no account needed. To sync between devices you can use your own tool, such as iCloud Drive, or pay for Obsidian Sync, which is end-to-end encrypted and costs $4/month billed annually or $5/month billed monthly.

The tradeoff is effort. There's no built-in journal lock, mood tracking, or "On This Day" view, and features like calendars and prompts come from community plugins you set up yourself. It feels more like a writing tool than a diary.

Choose Obsidian if you already keep notes there, or you care most about owning your writing in an open format.

Which One Should You Use?

Use Apple Journal if you only use Apple devices and want the easiest free switch.

Use Diarium if you want a one-time price and an automatic record of your day.

Use Journey if you need Windows, Android, Linux, or web access alongside your Mac.

Use Obsidian if your journal should live beside your notes as files you control.

Stay with Day One if shared journals, printed books, AI reflection, or its long track record matter more than the yearly price.

Before you switch, export your Day One journal and test the import in the new app with a few entries first. Import support differs between apps and changes over time, so check each app's help pages for the current options.

Final Verdict

Apple Journal is the best Day One alternative for most Mac users now that it has come to the Mac: it's free, encrypted, and syncs with your iPhone without any setup. Diarium is the best alternative for subscription-averse users, with a low one-time price and sync through your own cloud. Journey is the best cross-platform choice, and Obsidian is the best for long-term ownership of your writing. Day One is still the most complete and polished journaling app, so the question is whether you use enough of it to justify $49.99/year or more.
