Yes, based on the app's own description, Saber's dark mode is designed specifically for this use case. Unlike apps that only darken the surrounding interface, Saber's dark mode also darkens the notes themselves, so the page you're reading matches the rest of the screen. According to the site, this means you can read your notes in the dark without hurting your eyes.

What "cohesive dark mode" actually means

The key detail is in the wording on Saber's page: the dark mode "doesn't just darken the UI; it also darkens the notes themselves."

That distinction matters for a handwriting app. If only the menus and toolbars went dark while your notes stayed as bright white pages, you'd still be staring at a glowing rectangle in a dark room. Saber's approach is to bring the note surface into the dark theme too, so there's no bright page floating against a dark background.

Why this helps in low light

• Less contrast shock. A bright note page against a dark UI is the main source of eye strain when reading at night. Darkening the notes removes that mismatch.
• The stated goal is comfort. Saber's page frames the feature around reading in the dark "without hurting your eyes" — that's the intended benefit, not just an aesthetic option.
• It applies to the content, not just the chrome. Because the notes themselves change, the reading experience is consistent whether you're browsing folders or reading a page.

What to keep in mind

• The site describes the feature and its purpose, but it doesn't publish specific contrast ratios, color values, or brightness settings. If you need precise control over how dark the notes get, that detail isn't documented on the page.
• Dark mode is presented as one of several features alongside privacy, cross-platform sync, the highlighter, and nested folders — it's a built-in part of the app rather than a separate add-on.

The short answer

If your goal is reading handwritten notes in a dark room without a bright page glaring back at you, Saber's dark mode is built for exactly that: it darkens both the interface and the notes, which is the part that usually causes eye strain. For anything beyond that — exact color values or adjustable brightness — you'd need to check the app itself, since the site doesn't specify those details.

Saber organizes handwritten notes through unlimited nested folders and a home screen that surfaces your most recent notes. If you take a lot of handwritten notes and need a structure deeper than a flat list, the nested folder system is the main feature to evaluate. If you mostly jump back into whatever you were last working on, the recent-notes view covers that case.

Unlimited nested folders

Saber lets you organize notes into unlimited nested folders. That means you can build a hierarchy as deep as your material requires, rather than being capped at one or two levels.

A practical structure for a heavy note-taker might look like this:

• Courses → Semester 1 → Linear Algebra → Lecture notes, Problem sets
• Work → Client A → Meeting notes, Sketches
• Personal → Projects → Home renovation, Travel planning

The nesting is what makes this work at scale: a single "Notes" folder fills up fast, but a three- or four-level tree keeps each folder small enough to scan. Because the depth is unlimited, you can keep splitting categories as a subject grows instead of flattening it prematurely.

Quick access to recent notes

Saber also lets you quickly access your most recent notes from the home screen. This matters because deep folder structures are good for storage but slow for retrieval — if you have to click through four levels every time you reopen yesterday's page, the organization becomes a cost rather than a benefit.

The recent-notes view handles the common case: you were working on something recently, and you want it back. Folders handle the uncommon case: you need something you filed weeks ago and can only find by category.

How the two features work together

The design assumption is that most note retrieval is either very recent or categorical. If your retrieval pattern is different — for example, you search by keyword or by date across everything — check whether Saber supports that before committing, since the page evidence describes folders and recents rather than search.

What to check before relying on it

• Folder depth in practice. Unlimited nesting is supported, but a very deep tree can still be slow to navigate. Three to four levels is usually the point where scanning stays fast.
• Cross-device consistency. Saber syncs and edits notes across phones, tablets, and computers, so folder structure should follow you between devices. Confirm this matches your setup if you switch devices often.
• Privacy of the structure itself. Notes are encrypted and stored securely, and the server cannot read them. If folder names or note titles are sensitive, that encryption claim is the relevant one to verify in the privacy policy.

Saber is free and open source software, with the code available on GitHub — useful if you want to confirm how folders and sync are actually implemented rather than taking the feature list at face value.

Saber's highlighter is built so that going over the same area twice doesn't change the color, and the highlight renders underneath your text instead of on top of it. That combination matters most for handwritten notes, where you often sweep a marker across a word or line more than once and still need to read what's underneath.

The two behaviors that set it apart

No color buildup on repeat strokes

In many note apps, a highlighter behaves like a translucent layer of paint: each pass adds another layer, so overlapping strokes get darker or shift color. Saber's highlighter "doesn't overlap with itself and change color when you go over the same area again." The practical result is a flat, even highlight — a second pass over the same spot looks the same as the first.

Highlight sits under the text

Saber's highlighter "renders underneath the text, so you can still see the text clearly." Instead of tinting the ink, the highlight acts as a background band behind your handwriting. Your strokes stay at full contrast rather than being washed out by the marker color.

Why this fits handwritten notes

Handwriting is less uniform than typed text. Letters vary in height, ascenders and descenders cross the line, and a marker stroke rarely lands exactly where the last one did. Two consequences follow:

• Repeat passes are normal. You might drag across a line, notice you missed the tail of a word, and go back over it. With color buildup, that overlap becomes a visible blotch. With Saber's behavior, it stays even.
• Legibility is the whole point. If the highlight covered the ink, dense handwriting would get harder to read exactly where you marked it as important. Rendering underneath keeps the marked text as readable as the unmarked text.

What to check before relying on it

The site describes the highlighter's behavior but doesn't document platform-specific differences, input methods, or export behavior. If highlighting is central to how you annotate, verify on your own device:

1. Draw a highlight across a line of handwriting.
2. Pass over part of the same area a second time.
3. Confirm the color stays consistent and the ink underneath is still fully visible.
4. Repeat on each device you'd sync to, since Saber is cross-platform.

Where it fits in the app overall

The highlighter is one feature of a notes app that is otherwise oriented around handwriting, privacy, and organization. Saber is described as free and open source, with encrypted sync across phones, tablets, and computers, unlimited nested folders, and a dark mode that darkens the notes themselves rather than only the interface. If your main question is whether marking up handwritten pages stays readable, the highlighter's two behaviors above are the direct answer.

Saber is a free, open-source notes app built specifically for handwriting. It is aimed at people who take notes by hand — on a phone, tablet, or computer — and want those notes synced across devices, kept private, and readable in the dark. If you mainly type your notes, Saber's handwriting focus will matter less to you; if you write with a stylus or finger, it is designed around that workflow.

What Saber Does

The site describes Saber through a small set of core capabilities:

• Handwriting-first design — it is positioned as "the notes app built for handwriting," rather than a general notes app with a drawing feature bolted on.
• Cross-platform sync and editing — you can sync and edit your notes across all your devices, whether phone, tablet, or computer.
• Privacy through encryption — notes are encrypted and stored securely, and according to the site, not even the server can read them. Only you can access your notes.
• Unlimited nested folders — notes can be organized into as many nested folders as you need, with recent notes reachable from the home screen.
• A highlighter built for handwriting — the highlighter does not overlap with itself or shift color when you go over the same area twice, and it renders underneath the text so the text stays legible.
• Cohesive dark mode — dark mode darkens the notes themselves, not just the interface, so handwritten pages stay comfortable to read in low light.
• Open source — Saber is free and open source software, with the code available on GitHub.

Who It Fits

Privacy and Openness

Two claims do most of the work here. First, privacy: the site states that only you can access your notes, that syncing happens with encrypted storage, and that the server cannot read them — a privacy policy is linked for details. Second, openness: Saber is free and open source, and the code is published on GitHub, which lets you verify claims rather than take them on faith.

If encryption at rest and server-side unreadability are requirements for you, those are the specific points to check against the linked privacy policy and the source code before committing your notes to the app.

Practical Notes

• Pricing: the site describes Saber as free and open source software. No paid tiers, subscription details, or payment platforms are mentioned on the page.
• Account or login requirements: not specified in the available page content.
• Platform specifics: the site says phone, tablet, and computer, without listing particular operating systems or install methods.

For anything beyond that — exact platform support, sync setup, or account requirements — the GitHub repository and the linked privacy policy are the places to look, since the landing page does not cover them.

Saber keeps handwritten notes private by encrypting them so that only you can access them, and by publishing its source code so anyone can inspect how that protection works. According to the site, notes are encrypted and stored securely, and "not even the server can read them." The same page states that Saber is free and open source software, with the code available on GitHub.

What "private" means in Saber

The site's privacy claim rests on two ideas:

• Only you can access your notes. The page states plainly that only you can access your notes.
• The server can't read them. Because notes are encrypted, syncing them across devices doesn't require trusting the server with readable content.

That second point matters for a handwriting app. If you write on a tablet and read on a phone or computer, your notes have to travel between devices. Saber's approach is to sync encrypted notes rather than plain ones, so the sync path never exposes what you wrote.

The two mechanisms behind it

1. Encryption in storage and sync

Saber's page describes notes as "encrypted and stored securely," and says you can sync across devices "knowing that they are encrypted." The stated result is that the server cannot read your notes. In practice, this is the difference between a service that promises not to look at your notes and one whose design means it can't read them in normal operation.

2. Open source code you can review

Saber is free and open source software, and the site points to GitHub for the code. For a privacy-focused tool, this is the part that lets you verify claims instead of taking them on faith: you (or someone you trust) can read the implementation and see how encryption and storage are handled.

The page also links to a privacy policy for the formal description of data handling.

What this means for your decision

If your main concern is whether a handwriting notes app can be trusted with personal writing, Saber's answer is structural: encryption keeps the server out of your content, and open source lets you confirm it. If you need details the page doesn't cover — such as exactly which encryption scheme is used or how keys are managed — the GitHub repository and the privacy policy are the places to look, since those specifics aren't stated on the page itself.
