SimpleDay

SimpleDay is a beautiful, minimalist diary app built around one simple idea: one entry per day. No feeds, no clutter, no accounts to sign up for — just a calm space to write.

Write your thoughts, experiences, and memories in Markdown, and keep them private. Your entries stay on your device and, optionally, on a cloud server you control.

Features:

• Markdown support — formatting, lists, headers and more
• Live preview — toggle between edit and preview mode
• Minimalist, distraction-free interface
• One entry per day — a simple, focused approach to journaling
• Auto-save — never lose your thoughts
• App lock — protect the app with biometrics (fingerprint/Face ID) or your device PIN
• WebDAV sync — automatic backup to your own cloud (Nextcloud, ownCloud, etc.)
• Smart import — import existing entries from WebDAV on first launch
• Privacy first — no trackers, no ads, no analytics

Your data belongs to you. SimpleDay talks only to the WebDAV server you configure — nothing else.
