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.

SimpleDay is free software, licensed under the GNU GPLv3.

Fixed: the universal APK on GitHub shipped incomplete x86/x86_64 libraries, so it
crashed on startup on those devices and in emulators. The build now packages only
architectures it actually compiles, and an x86_64 build is published as well.
