Saber: Handwritten Notes

Adil Hanney

About this app

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!

Ratings and reviews

If I erase a mark the undo feature doesn't undo the erase? It seems to just skip over the operation and undo the creation of prior marks instead. If I undo once and redo twice it lets me bring the mark back, but it's still annoying. Please fix. Eraser and lasso tools don't have any changeable features from what I can tell, but the app is probably still usable for those with patience. I do like the actual writing tools. I'm willing to try and make the best of it for now.

Keep up the good work! Saber is a great cross platform app. But I will suggest you to add some features: 1. Shape adding options (circle, ellipse, square, arrow,line draw etc) should be more smooth 2. Add Horizontal scrolling also. 3. Pdf annotation/ import is slow 4. Add comment option 5. Add bookmark section in pages 6. Add a ruler 7. Add mind mapping tools 8. Add hand writing font option 9. Fix UI when it is full screen / landscape mode. 10. Make code option supported for many prog. lang.

I know this app is created mainly for doodling notes on big touch screen devices, but for more serious notes I prefer to type the texts to avoid "shaky" situation. The app is close to being unusable on 6" screen in text mode, keyboard takes the lower half of the screen, toolbar takes almost all of the top half, only leaves about 2 lines of text visible when typing. Maybe not for my use case, for me typed in text notes are more useful when syncing back & forth with computers. Good idea otherwise.
