Keep memories, daily notes, photos, moods, and travel moments in one private diary. Diarium is a personal journal and digital diary app for Android that helps you build a daily writing habit with reminders, rich entries, and no ads or subscription.

Your private diary for everyday life
Write quick notes, longer reflections, gratitude journal entries, bullet journal-style lists, or a personal journal of the moments you want to remember.

• Create diary and journal entries with text formatting and lists
• Add photos, drawings, audio recordings, files, tags, people, ratings, and locations
• Use daily reminders to keep your journaling routine going
• Revisit memories by date, tag, place, mood, or rating
• Capture thoughts, feelings, routines, hobbies, garden notes, and life moments

A password diary with lock
Diarium keeps your journal under your control. Use it as a private journal, secret diary, or password diary with Android-supported protection.

• Lock your diary with password, PIN, or fingerprint/biometric unlock
• Keep entries available offline on your device
• Use optional sync only when you want your journal on multiple devices
• No proprietary Diarium account is required for sync

Photo diary, mood journal, and travel journal
Turn everyday moments into a richer memory journal. Diarium can help you remember where you were, what you did, and how you felt.

• Build a photo diary or photo journal with pictures from your day
• Add audio recordings when you want a voice diary moment
• Track your mood with stars and tracker tags
• Use it as a mood diary, mood journal, or simple mood tracker
• Create a travel diary with locations and a map view of your journeys

Helpful day context, added automatically
Diarium can show useful context for each day so journaling feels easier. On Android, supported integrations can add information such as calendar events, photos and videos from your camera roll, weather, WorkingHours, Google Timeline, fitness activity, social activity, tasks, and entertainment activity.

This helps you write about the day without starting from a blank page. Some integrations and automatic feeds require Diarium Pro.

Continue on phone, tablet, laptop, and desktop
Diarium is available for Android, Windows, iOS, and macOS. With optional sync through your own supported cloud storage, you can continue journaling across phone, tablet, laptop, and desktop versions.

Supported sync providers include OneDrive, Google Drive, Dropbox, iCloud, and WebDAV. Sync is optional and uses your personal cloud storage instead of a Diarium account.

Import, backup, and export your journal
Moving from another diary app or journal app? Diarium supports migration from several journal apps, including Day One, Diaro, Journey, Daylio, Daybook, Evernote, Memorize, and more.

• Back up your private journal with database import and export
• Export entries as Word, HTML, JSON, or plain text
• Use Word export for printable journal entries with Diarium Pro
• Keep your memories portable and under your control

No ads. No subscription.
Diarium is free to start on Android and includes an optional Diarium Pro upgrade for advanced features such as sync, unlimited attachments per entry, app/feed integrations, custom fonts and font size, widgets, weather in entries, and Word export.

Diarium Pro can be tested during a 7-day evaluation period and is a one-time purchase, not a subscription. Your Diarium Pro purchase is linked to your Google Play account and unlocks Pro access for Android; other platforms may require a separate purchase.
