Our verdict

Second of our top three journaling apps

For: People who want to pay once and keep the journal themselves

Diarium keeps the journal on your own device with no account or sign-up. It is free to use on Android, iPhone, iPad and Mac, and Pro is a one-time purchase, not a subscription: $14.99 per platform, or $19.99 for the Windows app. Entries take rich text, photos, video, audio and files, and can be browsed by calendar, timeline, map or an On this day page. Its iPhone and iPad app averages 4.8 from about 2,000 ratings. It is second because it asks more of you than Day One: Pro is bought separately for each platform, sync needs Pro and runs through your own OneDrive, Google Drive, Dropbox, iCloud or WebDAV storage, no web version is listed, and Windows has no free version.

Good for

  • 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

Worth knowing

  • 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.
