Saber is the notes app built for handwriting.
It's designed to be as simple and intuitive as possible, while still delivering unique features that you'll actually use. Additionally, Saber is available across all your devices, large and small, and syncs between them seamlessly.
Notably, it can invert your notes when you're in dark mode. This allows you to write with white ink on a black background, which is much easier on the eyes in low-light environments like when the teacher turns off the lights in class. Images and PDFs are also inverted, so you can still use a digital printout or a textbook without the fuss.
Saber uses a dual-password system to protect your notes from anyone but you, even if they have complete control over the server. You can safely store your notes on the official Saber server, another server, or even host your own!
The app is completely open-source so that anyone can view the source code and see exactly what it's doing and how it handles your data. Many other note-taking apps are closed-source and proprietary, meaning that their inner workings are a mystery to the public.
As someone who studies maths, highlighting multi-line equations was always a hassle with other apps, where the highlighter would change color when it overlapped with itself. Another problem I had was that in some apps, the highlighter would render on top of the text, fading it out and making it hard to read. Saber's highlighter has no such issues. It utilizes canvas compositing to render the highlighter in a way that is consistent with/better than traditional paper, where it handles overlaps and maintains color consistency.
Saber has everything you need to keep your notes organized. Create folders inside folders inside folders to your heart's content with no limit on the number of nested folders. And even though a note may be buried deep within a nested folder, you can still access it easily with your most recent notes always available on the home screen.
Discover a whole new way to capture and organize your thoughts with Saber. Whether you're a student, professional, or creative mind, Saber is your trusted companion for digital handwriting. Download now and let your ideas flow freely!

https://docs.flutter.dev/get-started/install
git clone https://github.com/saber-notes/saber.git
flutter pub get
Setup for the super_clipboard package can be summarised as:
- Install Rust
- Install NDK 26.1.10909125 if you're building for Android
sudo apt install libsecret-1-dev libjsoncpp-dev libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev webkit2gtk-4.1-dev
# Or for Fedora...
sudo dnf install libsecret-devel jsoncpp-devel gstreamer1-devel gstreamer1-plugins-base-devel webkit2gtk4.1-devel
flutter build linux
This is good enough for using on your own computer, but if you want to redistribute your build, you need to use a predictable environment: fork this repo and use the GitHub Action Build for Linux instead.
flutter build apk
You may need to generate a signing certificate and create the android/key.properties
file.
More information on https://docs.flutter.dev/deployment/android#create-an-upload-keystore
Note: FOSS/F-Droid builds are done slightly differently:
./patches/remove_proprietary_dependencies.sh
flutter build apk
flutter build windows
The Windows installer is created with Inno Setup. To create an installer of your own, run the above build command, then edit and run installers/desktop_inno_script.iss with Inno Setup Compiler.
If you have a macOS computer, you can
build for iOS
with flutter build ipa
or
build for macOS
with flutter build macos
.
If you don't, fork this repo and use the GitHub Action Build for macOS and iOS. Alternatively, follow this YouTube tutorial How to compile a flutter application to iPhone with no mac (free | no jailbreak) to manually build with Codemagic.

Check _missing_translations.yaml to see if any translations are missing.
- Use this link
to edit
_missing_translations.yaml
. - Update your
_missing_translations.yaml
file with your translations, e.g. updating German (de)de: editor: newerFileFormat: title: Diese Notiz wurde mit einer neueren Version von Saber bearbeitet subtitle: Wenn du diese Notiz bearbeitest, können Daten verloren gehen. Möchtest du die Notiz trotzdem öffnen? openAnyway: Trotzdem öffnen cancel: Abbruch # ignore the other languages...
- Open a pull request! I'll do the rest
- Look for your locale code here,
e.g.
hi
for Hindi,fr
for French,bn
for Bengali,ar
for Arabic, etc. - Use this link
to create a new file in
lib/i18n/
calledstrings_XX.i18n.yaml
whereXX
is your locale code. - Copy the contents of an existing file like
lib/i18n/strings.i18n.yaml
and replace the translations with your own. If you don't know the translation for a string, just delete the line. - Open a pull request!

's Getting Started for more information.
We have 2 formats for app store descriptions:
-
F-Droid/Play Store:
i. Open
metadata/en-US/
and copy thefull_description.txt
andshort_description.txt
files into themetadata/XX/
folder whereXX
is your locale code. Then translate the contents of the files.ii. Changelogs are automatically translated from the English version. If you spot a mistake, please edit the translated changelog in
metadata/XX/changelogs/<version-code>.txt
whereXX
is your locale code. -
Linux .desktop file:
i. Open
flatpak/com.adilhanney.saber.desktop
and add a line for theComment
key with the following format whereXX
is your locale code:Comment[XX]=Your translation
If you also need to translate the
Name
key, do the same thing. -
Flathub (optional):
i. Since this is slightly more technical, you can skip the Flathub part if you want to and I'll copy the translations from the above section.
ii. In
flatpak/com.adilhanney.saber.metainfo.xml
before the</description>
closing tag, add a line for your translation with the following format whereXX
is your locale code:<p xml:lang="XX">Your translation</p>
iii. In the same file, you can translate the changelogs by doing the same thing in the
<release>
tags before their</description>
closing tag.
