Diarium is a private diary and journaling app developed by Timo Partl. It helps users record their day-to-day life with text, photos, audio, locations and other details, and then revisit these memories later through a calendar, timeline or map. The Windows version is sold through the Microsoft Store, and the app is also available for Android, iOS and macOS.
Overview
Diarium provides users with a flexible and intuitive environment for keeping a journal entry for every day. The calendar is the starting point: users pick a date, write a heading and text, and attach photos, audio recordings, files, tags, ratings and locations. The app can also add context automatically from other sources, such as pictures, calendar events, weather, completed tasks and fitness data. No proprietary account is required, and the journal can be protected with a password, PIN or Windows Hello.
Diarium makes it easy to keep track of your daily activities, thoughts and feelings.
Features
•Journal entries: Diarium lets users write formatted entries and lists for any day, each with a heading and text, and supports dictation.
•Multimedia: Photos, drawings, audio recordings, videos and files can be attached to each entry to capture more than words.
•Calendar view: A monthly calendar shows the days with entries, and the Jump to day command opens any date directly.
•Timeline and map: Entries can also be viewed as a timeline, on a map by location, or through the attachments view.
•On this day: The app brings back entries written on the same date in earlier years.
•Tags, people and ratings: Users can organize entries with tags and people and record their mood with star ratings and tracker tags.
•Search: Fast search by keywords and tags makes older entries easy to find.
•Integrations: Supported integrations can add data from the camera roll, calendar, weather and services such as Microsoft To Do, Todoist, GitHub, Google Fit, Strava, Fitbit, Trakt and Last.fm.
•Reminders and templates: Daily reminders help build a writing habit, and journal templates speed up recurring entries.
•Privacy: The journal can be locked with a password, PIN or Windows Hello, and users can choose how soon Diarium locks after they leave the app.
•Cloud sync: Optional sync uses the user's own OneDrive, Google Drive, Dropbox, iCloud or WebDAV storage and does not require a Diarium account.
•Import: Entries can be migrated from Day One, Diaro, Journey, Daylio, Evernote, Memorize and other journal apps.
•Export and backup: Entries can be exported as Word, HTML, JSON or plain text, and the diary database can be backed up.
•Personalization: On first start users choose an accent color, app theme and font, which can be changed later in the settings.
Conclusion
Diarium is a focused journaling app rather than a task or calendar manager. It combines quick daily notes with rich multimedia memories and strong privacy options, and it received a Microsoft Store Award in 2024. On Windows it is a one-time purchase that already includes all Pro features, with no ads, subscription or in-app purchases, while the Android, iOS and macOS versions are free to start with an optional Pro upgrade.
