1 Second Everyday vs Diarium

1 Second Everyday

• People who want a visual diary they can keep up in a few seconds a day
• Parents recording a child's first years as a single video
• Year-in-review or trip recap videos without manual editing

Diarium

• People who want to pay once instead of subscribing
• Journaling across Windows, Android, iPhone, iPad and Mac
• Keeping a journal on your own device and cloud storage with no account
• Pulling calendar, fitness and social activity into daily entries

1 Second Everyday

• Mobile only: there is no desktop or web version, and on iPad it runs as the iPhone app at iPad size.
• Content does not sync between devices. Moving a project means restoring a 1SE backup, which needs Pro and replaces what is on the device.
• Free accounts get one Journal project and one 1-second snippet a day, with no cloud backup.
• The help center says there is no monthly plan: Pro is $49.99 a year or a one-time $249.

Diarium

• Pro is bought separately for each platform, and iOS and macOS count as separate purchases.
• Cloud Sync, unlimited attachments, Word export, widgets and integrations require Pro.
• There is no free version on Windows, where Diarium is a paid app listed at $19.99 in the Microsoft Store.
• By default the journal is stored only on the device, so without Cloud Sync you need to make your own backups.

1 Second Everyday

Journal projects

A calendar project where each day gets at least one second taken from a video or photo. Free accounts are limited to one Journal project and one snippet a day.

Mashing into a movie

The app compiles snippets into one continuous video of any length, such as a month, a season or several years. Pro adds HD and 4K export and removes the date stamp and 1SE branding.

Freestyle and Freestyle Collab

Freestyle projects are not tied to the calendar and suit trips or events. Freestyle Collab lets up to six people add snippets to one project; only one of them needs Pro.

Smart-Fill and reminders

Smart-Fill fills a month of days in one tap, and daily reminders prompt you to capture a moment. You can also add a private note to a day.

Music and editing tools

Pro includes a music editor with royalty-free tracks and access to your own music library, plus brightness and volume control for each snippet. Filters are iOS only.

1SE Cloud backup

Pro backs up all projects, encrypted, to 1SE's servers on Amazon Web Services in the US. After a subscription ends the backup is kept for 12 months and then deleted.

Diarium

Rich entries with attachments

Entries support rich text formatting, tags and locations, plus photos, videos, audio recordings, PDFs and other files. Several entries can be created per day.

Calendar, timeline and map views

Look back through a calendar, a scrolling timeline, a map of places visited, an attachments gallery and an On this day page with optional notifications.

Automatic feeds

Connected services add context to a day: camera roll photos, calendar events, weather, Strava and Apple Health data, Microsoft To Do tasks and Last.fm scrobbles. Some feeds require Pro.

Sync through your own cloud

Pro syncs the journal across platforms using your OneDrive, Google Drive, Dropbox, iCloud or WebDAV storage. The uploaded data is compressed and encrypted.

Import and export

Migrates journals from Day One, Diaro, Journey, Daylio, Diarly, Daybook, Evernote and Apple Journal, and exports to Word, plain text, HTML or JSON.

Lock without an account

No login or sign-up is required and the app carries no ads. The journal can be protected with a password, PIN or biometrics such as Face ID and Windows Hello.
