- Most complete journal app: Day One. End-to-end encrypted, on almost every platform, with a free plan.
- Free and already on your iPhone: Apple's Journal app, end-to-end encrypted in iCloud.
- Guided morning and evening prompts: Stoic. A journal in two taps: Daylio.
- Pay once, keep it in your own cloud: Diarium. AI that talks back: Rosebud (paid only since 30 Sep 2026) or Reflectly.
- A journal that fills itself in: Cloudbun (our app, on the App Store for iPhone). Talk to your cloudbun about your day and the journal writes itself.
A journaling app can be a blank page, a set of prompts, a two-tap mood log or a companion that asks you questions. They all promise the same thing: a place to put your thoughts. What really separates them is how much effort they ask for, what they cost over time, and where your most private words end up.
This guide compares eight journaling apps on those things: what's free, what it costs, where it runs and what it says about privacy. Every fact comes from the app's own website, help centre or US App Store listing, checked on 3 November 2026. Privacy claims are quoted as each company states them; we haven't audited anyone's encryption.
Full disclosure: Cloudbun is our app. It's here because it's a different kind of journal, one you talk to instead of write in, and we've been as plain about its limits as anyone else's. Nobody paid to be included and there are no affiliate links. Ratings are the App Store's, not ours.
Does journaling actually help?
Most of the research is on expressive writing: writing about your thoughts and feelings on something that matters to you. A large review of 146 randomised studies found the effect was positive and significant, but small on average (Frattaroli, 2006). That's a fair summary of journaling in general: often helpful, rarely dramatic.
Gentler, positive journaling has some evidence too. In a small trial, 70 adults with medical conditions and raised anxiety did 15-minute online "positive affect journaling" sessions three days a week for 12 weeks. Compared with their starting point, they reported less mental distress and more wellbeing (Smyth et al., 2018). It was a preliminary study, so treat it as encouraging, not proof.
No app is required for any of this, and a journal isn't a treatment for mental health conditions. An app's real job is to make the habit easier and the words safer. If you're new to it, start with how to start journaling.

The 8 best journaling apps
1. Cloudbun (our app): best if you'd rather talk than write
Cloudbun is a cozy self-care companion with a journal that fills itself in. You tell your cloudbun about your day, by voice or by typing, for a minute or five. It picks out what you did and what you still want to do, and every check-in becomes a day in your journal, with a gentle mood calendar. What you did also turns into materials for building your floating island.
- What it does well
- No blank page and no streaks. Venting counts, and every check-in pays. Your journal lives on your phone, with a private backup only your account can read; when your cloudbun reads your day, your words go through our server to an AI service for that one read, never logged or kept. Friends can visit your island but never see your journal. No ads on any plan.
- Where it falls short
- It's new and iPhone only. It's built around short daily check-ins, so if you want long entries, photos, templates and export, a dedicated journal like Day One or Diarium does more. Free accounts get 5 smart check-ins a month; after that your cloudbun makes simpler guesses on your phone.
- Pricing
- The journal is free. Cloudbun Plus ($9.99 a month or $69.99 a year in the US, no free trial) adds your own story every Sunday and each month.
- Bottom line
- For people who've bought three notebooks and filled none. More on voice journaling here.
2. Day One: best all-round journal app
Day One is the long-standing favourite: entries with photos, video and audio, multiple journals, a calendar view, streaks and prompts. It runs on iPhone, iPad, Mac, Apple Watch, Android and Windows, and in any web browser.
- What it does well
- Day One says end-to-end encryption is on by default for new journals, that the key is held on your device, and that it "never has access" to it. The free plan includes unlimited text entries and journals, daily prompts, search and encryption. Editors' Choice, 4.8 from about 119,000 ratings.
- Where it falls short
- The free plan is limited to one device and one photo per entry. AI features are in the top tier. Its App Store privacy label lists a wide range of data linked to you, including location and contact info.
- Pricing
- Free Basic plan. Silver is $49.99 a year (sync and more media) and Gold $74.99 a year (adds AI chat and summaries), with a free month's trial in the app.
- Bottom line
- The one to choose if you want a journal for years, with everything in one place.
3. Apple Journal: best free journal for iPhone
Apple's Journal app comes with the iPhone and, since macOS Tahoe 26, the Mac. You can add photos, music, drawings and audio recordings, and it can suggest moments to write about.
- What it does well
- Free, simple and private. Apple says journaling suggestions are created on device, and that "all Journal entries are end-to-end encrypted when stored in iCloud". You can lock the app with Face ID, Touch ID or your passcode.
- Where it falls short
- Apple only, with no Android or web access. It's deliberately simple, so there are few templates or stats.
- Pricing
- Free.
- Bottom line
- The easiest place to start: it's already on your phone.
4. Stoic: best for guided morning and evening journaling
Stoic gives you a structure: a morning routine to plan the day and an evening one to reflect, with daily prompts, mood tracking, breathing, meditation and a dream journal. AI features come with a separate paid tier.
- What it does well
- Great prompts when you don't know what to write, and you can keep journaling for free. Its help centre says data is stored locally on your device by default, with optional iCloud sync. Editors' Choice.
- Where it falls short
- It has streaks and badges. If you turn on AI features, the help centre says your current entry is sent to an outside AI provider and may be kept there for up to 30 days. Prices on the App Store aren't labelled by period.
- Pricing
- Free to start. Premium and Premium AI tiers, plus a $299 lifetime option.
- Bottom line
- For people who like a routine and a nudge. Our self-care journal prompts work in any app.
5. Daylio: best for journaling without writing
Daylio is a "micro-journal". You pick a mood and tap the activities you did, and it builds stats, a Year in Pixels and charts. You can add notes, photos and voice memos when you want to say more.
- What it does well
- A full entry takes seconds. Its site says "We don't send your data to our servers", and backups go to your own iCloud or Google Drive. There's a free unlimited version.
- Where it falls short
- It's built for logging rather than long writing. The PIN lock on iOS, advanced stats and automatic backups are Premium. Recent release notes talk about keeping your streak alive.
- Pricing
- Free. Premium has a 7-day free trial; App Store prices aren't labelled by period.
- Bottom line
- Perfect if a few taps a day is all you've got.
6. Diarium: best one-time purchase journal
Diarium is a full diary app with attachments, mood star ratings and tracker tags. It runs on iPhone, iPad, Mac, Windows, Android and Chromebooks.
- What it does well
- No ads, no subscription and no account. Sync is optional and uses your own iCloud, OneDrive, Google Drive, Dropbox or WebDAV storage. Its App Store privacy label lists only diagnostic data, not linked to you.
- Where it falls short
- Pro is bought separately on each platform, and sync needs Pro. Its site describes password, PIN and biometric locks but doesn't mention encryption.
- Pricing
- Free, with Pro at $14.99 once on iOS and a 7-day evaluation.
- Bottom line
- The pick if you hate subscriptions and want your diary in your own cloud.
7. Reflectly: best for light AI prompts
Reflectly asks you questions to help you write, with mood tracking, graphs and daily, weekly and monthly overviews. It describes itself as a journal "utilizing artificial intelligence".
- What it does well
- Friendly and quick, with prompts that save you from the blank page. About 82,000 ratings, averaging 4.6.
- Where it falls short
- Unlimited stories and advanced stats are Premium, and prices aren't labelled by period. It has a streak widget. Its privacy label lists contact info and identifiers as linked to you. English only.
- Pricing
- Free with Reflectly Premium; prices are shown in the app.
- Bottom line
- A gentle starter if you like being asked questions.
8. Rosebud: best for in-depth AI journaling
Rosebud is built around AI: it asks follow-up questions, notices patterns across entries, offers voice journaling in 20 languages and gives weekly insights.
- What it does well
- The most conversational journal here, with mood and goal tracking. It says your data is "encrypted in transit and at rest", and its listing says it isn't a substitute for professional care.
- Where it falls short
- Its help centre says the free plan was retired on 30 September 2026, so it's now a paid app (its homepage still says it's free to use). Rated 18+. Your entries are processed by AI on its servers.
- Pricing
- Rosebud Bloom is $12.99 a month or $107.99 a year, with a free trial. Higher "Thrive" tiers cost more.
- Bottom line
- For adults who want an AI to think things through with and are happy to pay.
A quick privacy checklist for journal apps
Your journal may be the most personal thing on your phone. Before you commit, check:
- Where entries live. On your device only, in your own cloud, or on the company's servers?
- Who holds the key. "End-to-end encrypted" means the company says it can't read your entries. Day One and Apple say this for their journals.
- What AI features send. Apps with AI usually send entries to an outside service. Read what they say about retention and training.
- The App Store privacy label. It's self-reported, but "Data Used to Track You" and "Data Linked to You" are worth a look.
- Export. Can you take your entries with you if you leave? Rosebud, for example, says you can export everything any time.
- A lock. Face ID or a PIN helps if others use your phone.
Which journaling app should you pick?
- You want one journal for life: Day One.
- You want free and simple: Apple Journal, or the free versions of Day One, Daylio and Stoic.
- Privacy comes first: Day One or Apple Journal (end-to-end encrypted), or Daylio and Diarium (on your device or your own cloud).
- You never know what to write: Stoic or Reflectly.
- You don't like writing: Daylio or Cloudbun.
- You hate subscriptions: Diarium.
- You want AI to talk it through with: Rosebud, knowing it's now paid only.
Questions people ask
What is the best free journaling app?
Apple's Journal app is completely free on iPhone. Day One, Daylio, Stoic and Diarium all have free versions you can keep using, with paid extras.
What's the most private journaling app?
Day One says new journals are end-to-end encrypted by default, and Apple says Journal entries are end-to-end encrypted in iCloud. Daylio and Diarium keep entries on your device or in your own cloud storage. Always read the current privacy policy yourself.
Is Day One worth paying for?
If you journal across several devices or add lots of photos, probably; sync and more media are in its paid plans. If you write text on one phone, the free plan may be all you need.
Is Rosebud still free?
No. Rosebud's help centre says its free plan was retired on 30 September 2026, and existing entries can still be exported. Its paid plan starts at $12.99 a month.
Can a journaling app replace therapy?
No. Journaling can help you notice and untangle your thoughts, but it isn't a treatment. If you're struggling, a doctor or therapist can help in ways an app can't.
Final thoughts
The best journaling app is the one you'll open on a tired Tuesday. If you love writing, pick a beautiful blank page. If you don't, pick something that asks for a tap, a question or a few spoken sentences. And whichever you choose, check where your words go before you pour your heart into it.
