Saber – notes app built for handwriting

Saber is a 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.

This is free and open source software.
