Diarium

Diarium

• Cross-platform
• Passcode/biometric security for the apps
• Encrypted db¹
• Can sync to your own server via WebDAV; I'm using my Nextcloud instance
• Comparable feature set to Day One
• Haven't yet tested export functionality
• One-time purchase, not a subscription

Update: No templates support in macOS app.
