# Saber (open-source notes app)

> Saber is a free, open-source notes app for Android and iOS. The notes app built for handwriting. It has 4,885 GitHub stars and is released under the GPL-3.0-only license, and you can install it from F-Droid, Google Play and the App Store.

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.
