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. SimpleDay is free software, licensed under the GNU GPLv3.
