Apple made a Journal app for the iPhone and brought it to the Mac later, still shaped like a phone app. Day One made a good Mac app and put it behind a subscription. I wanted a journal I could open on my Mac, type into at a real keyboard, and pay for once — so I built Cozy.
A diary app for Mac, if that's the word you use
Some people call it a journal, some people call it a diary. It's the same thing here: you sit down at the end of the day and write what happened. Cozy works either way — a dated entry, a calendar to move through the months, and a folder of files you own at the end of it. If you've been searching for a diary app for Mac and getting phone apps or subscriptions, this is the desk version.
It's a native Mac app, not a web page in a window
Cozy is a real macOS application. It follows the system light and dark mode, so it looks right at 8am and at midnight. macOS Text Replacements work in the editor — the shortcuts you already type expand the way they do everywhere else on your Mac.
Quick entry from the menu bar
Most thoughts worth writing down show up while you're doing something else. Cozy lives in the menu bar with a global shortcut, ⌘⇧C, that opens a small capture box. You write the line, hit save, and get back to what you were doing without ever opening the full window.
Photos and video from your iPhone drop straight in
Drag an iPhone photo onto an entry and it goes in — HEIC and all, no converting first. iPhone video in .mov format works the same way, and so do audio files and voice memos. The things you already capture on your phone become part of the day you're writing about.
Your journal is a folder of plain files
- Plain Markdown. Every entry is a .md text file you can read in any editor, now or in ten years.
- No account. There's nothing to sign up for and no password to forget.
- No server. The app doesn't phone home, so it works offline and nothing leaves your Mac unless you move it.
- No cloud lock-in. Because it's just a folder, you can put it in iCloud yourself and open the same journal on another Mac or a PC.
One price, all your Macs
Cozy is $35, paid once. That single license covers every Mac you own — your Windows PCs and your iPhone too — so there's no per-device math and no subscription quietly renewing every year.
How does Cozy compare to other Mac journaling apps?
I built one of these, so take my opinion for what it is. But the facts in this table are the ones I'd want if I were choosing, and where another app is better than Cozy, it says so.
| Cozy | Day One | Apple Journal | Obsidian | |
|---|---|---|---|---|
| Price model | One-time — $35, all your Macs and PCs, iPhone included | Subscription — $49.99–$74.99 / year | Free | Free for personal use · Sync $48 / year |
| Where entries live | Plain Markdown files in a folder you pick | Day One's servers, own format, end-to-end encrypted | Inside Apple's Journal system | Plain text files in a folder you pick |
| Offline | Yes — there's no server to reach | Sync needs a connection | Sync needs a connection | Yes — files are on your disk |
| Platforms | Mac, Windows, iPhone | Mac, Windows, iOS, Android, web | Apple only — iPhone, Mac | Mac, Windows, Linux, iOS, Android |
| Sync | You set it up: iCloud Drive (required for iPhone), or any folder sync between computers | Built in and handled for you | iCloud, automatic | Obsidian Sync, or iCloud / Dropbox yourself |
What are the other Mac journal and diary apps worth knowing?
Day One
The most polished journal on the Mac, and the one most people try first. It syncs everything for you across Mac, iPhone, iPad, and Apple Watch, handles photos and video well, and its end-to-end encryption is genuinely good. The trade is the deal itself: $49.99 a year for Silver or $74.99 for Gold, and your entries sit on Day One's servers in a format only Day One reads, so leaving means exporting. If you want mobile today and don't mind renting, it beats Cozy. Cozy vs Day One →
Apple Journal
Free, quiet, and Apple's privacy claims here aren't marketing — entries are encrypted on device and in iCloud. It started on the iPhone and the Mac version came later, still carrying the phone's shape. Your journal lives inside the Journal system and your Apple ID, so it isn't there the day you sit down at a Windows machine, and getting your writing out as files means an export. Cozy vs Apple Journal →
Obsidian
Free for personal use, and it shares Cozy's most important idea: your writing is plain text files in a folder on your own Mac. Lots of people journal in it. The difference is how much it asks of you — you pick the folders, tags, templates, and plugins, and there's no calendar, mood, or moments timeline unless you build them. Sync is $4 a month billed annually, or you point it at iCloud like Cozy does. Cozy vs Obsidian →
Bear
The best-looking notes app on the Mac, and I still use it every day for notes. It's Apple-only, $2.99 a month or $29.99 a year for Pro, and notes live in its own database with export to plain files. As a journal it never worked for me: you can't pick a date for a note, can't go back and write into a specific day, and there's no calendar. Cozy vs Bear →
Diarium
Worth a mention if you like the idea of a journal that fills itself in — steps, weather, photos, social posts — and it runs on Mac and Windows both. Entries live in its own database and sync through OneDrive, Google Drive, Dropbox, or Diarium Cloud. Cheap to buy per platform, with a Premium subscription for the extras. Cozy vs Diarium →
Where Cozy falls short
Two things, and I'd rather you hear them from me. There's no iPad app and no Android app yet — Cozy runs on Mac, Windows and iPhone, so if your journaling lives on an iPad or an Android phone, Day One serves you better today. And there's no sync service. You drag the folder into iCloud or Dropbox and it syncs like your other files, which takes a minute and then works, but it is a minute Day One doesn't ask of you.
If you came here from a Reddit thread
People keep asking, on Reddit and elsewhere, for a Mac journaling app that isn't a subscription and isn't iPhone-only. I looked for that app, couldn't find one I trusted, and built Cozy instead. If that's the thread that sent you here, this is the one I'd point you to.
Head-to-head: Cozy vs Day One, Cozy vs Apple Journal, Cozy vs Obsidian, Cozy vs Bear, Cozy vs Diarium.
