Plume
A Journal App for Mac and iPhone
That Stays in Sync
Most of us think on the phone and write on the Mac. A good journal app for both should feel like one journal, not two. That means three things: one purchase for every device, sync you can trust with your most private writing, and a Mac app that feels native, not stretched. Here's what to look for, and a simple way to journal on a MacBook.
What to look for in a Mac and iPhone journal app
Plenty of apps run on both. Fewer get the parts in between right.
One price, every device
Some apps sell each platform separately. Others put sync behind a subscription tier. Check what it costs to have the same journal on your phone and your laptop, not just on one of them.
Sync that can't be read in transit or at rest
A journal syncs through someone's servers. Ask whether entries are encrypted before they leave your device, and who holds the key.
Sync that stays optional
If you only write on one device, you shouldn't need an account or a cloud at all. Sync should be a choice you make, not a condition of using the app.
A real Mac app
Keyboard shortcuts, separate windows, a menu bar presence. An enlarged iPhone app works, but it rarely becomes a habit on a laptop.
How Plume handles Mac and iPhone
We make Plume, so read this section as our description, not a review. It's how we answered the four questions above.
One purchase for iPhone, iPad and Mac
Buy once and it's yours on all three. The first 21 writing days are free. Skip a week and the trial doesn't burn. After the trial, the app goes read-only: you can still read, search, sync and export everything you wrote.
Encrypted, optional iCloud sync
Plume works without an account, and sync is off until you turn it on. When you do, entries go through your own private iCloud storage and are encrypted before upload with ChaCha20-Poly1305, using a key derived from a sync passphrase you choose. A second device needs the same iCloud account and the same passphrase. How the privacy works has the details.
Built for the Mac
A menu bar app with today's to-dos as a real checklist. A ⌘K command palette with date search. Global shortcuts you record yourself, and a hold-⌘ overlay that shows every one. Any section can open in its own window. Voice journaling runs on-device, with a small pill in the toolbar.
Quick on the iPhone
Three guided prompts (gratitude, memory, accomplishment), a 1–5 mood rating, voice entries, Face ID lock, and Siri shortcuts to add a line without opening the app.
No ads, no telemetry, no tracking SDKs. Export to plain text or JSON whenever you like. If you're coming from Day One, Plume imports its JSON export with a preview first.
How to journal on a MacBook
A laptop is where most of us already type all day. That's an advantage, if the journal doesn't feel like more work. A routine that holds up:
Pick one time and one trigger
Tie writing to something that already happens. Opening your MacBook after lunch. Closing it at the end of the workday. The trigger matters more than the hour.
Keep the journal one keystroke away
If writing starts with finding an app in the Dock, you'll skip it on busy days. A global shortcut or a menu bar icon removes that step.
Start with a prompt, not a blank page
One thing you're grateful for, one moment worth remembering, one thing you got done. Three short answers take about two minutes.
Go full screen for longer entries
When you have more to say, hide everything else. A distraction-free canvas makes a laptop feel less like a workstation.
Let the phone catch the rest
Thoughts arrive away from the desk. Jot them on your iPhone and expand them on the Mac later, in the same entry.
Any MacBook that runs a current macOS is plenty for a journal app, including a MacBook Air. What matters more is how quickly you can get from "I should write" to the first sentence. For more on building the habit, see how to start journaling.
Other options worth knowing
Apple Journal is free and now runs on Mac with macOS Tahoe 26 and on iPad with iPadOS 26. Apple says entries are end-to-end encrypted in iCloud. If you want simple and free, it's a good start. We cover it in Is Apple's Journal app on Mac and iPad?
Day One is polished and runs on Mac and iPhone, with end-to-end encryption on by default for new journals. Multi-device sync is part of its paid plans rather than the free tier.

Frequently asked questions
What is the best journal app for Mac and iPhone?
It depends on what you value. Apple Journal is free and runs on both with the 26 releases. Day One is polished, with sync in its paid plans. Plume is one purchase for iPhone, iPad and Mac, needs no account, and offers optional sync encrypted with your own passphrase. We make Plume, so try more than one.
Does Plume sync between iPhone and Mac?
Yes, if you turn it on. Sync is optional and uses your private iCloud storage. Entries are encrypted before upload with a key derived from a sync passphrase you choose, and each device needs the same iCloud account and passphrase.
Do I need to buy Plume separately for Mac and iPhone?
No. One purchase covers iPhone, iPad and Mac. The first 21 writing days are free, and after that the app goes read-only instead of locking you out.
Is a MacBook Air good enough for a journal app?
Yes. Journal apps are light. Any MacBook that runs a current version of macOS, including a MacBook Air, handles them comfortably.
How do I make journaling on my Mac a habit?
Tie it to something you already do, like opening your laptop after lunch. Keep the journal one shortcut away, start with a short prompt instead of a blank page, and capture thoughts on your phone to finish later on the Mac.
