Logseq vs Obsidian on a Boox Tablet: Which Note App Copes With E-Ink and Offline Sync

A Boox tablet is an Android device that happens to have an e-ink screen, which means it will install almost any note app you like. That is the appeal and the trap. Obsidian and Logseq both install from the Play Store in a minute, both open your notes, and both feel fine for the first ten minutes. The differences show up a week later, when your graph has grown, your sync has hit its first conflict, and you notice which app makes the screen flash every time you type.

I keep a working knowledge base of a few thousand notes and have run it on Boox tablets in both apps, with the same files, the same sync setup, and the same habits. This is not a feature checklist. It is about which app copes with the two things a Boox is bad at: redrawing the screen quickly, and being online.

Obsidian for most, Logseq for outliners

Obsidian is the better choice for most people on a Boox. Its notes are whole pages that redraw cleanly, it has an easy-to-read view, and its sync options are more mature. It handles reading and light capture on e-ink with less fuss.

Logseq is worth the extra tuning if you think in outlines and daily journals. Its block-based model is a better fit for quick capture into today’s journal, but it redraws more of the screen as you work, and it is more sensitive to how you sync.

Why note apps behave differently on e-ink

An e-ink screen does not refresh like an LCD. Every change on screen costs time and leaves faint ghosting behind until a full refresh clears it. Apps built for phones assume redrawing is free. They animate, they slide panels in and out, and they repaint large areas when one small thing changes. On e-ink, every one of those habits turns into a flash, a smear, or a lag.

Both Obsidian and Logseq are built on web technology and were designed for fast screens, so neither is naturally e-ink friendly. But they redraw in different ways, and that makes a bigger difference than any feature list.

Boox helps a little. Its settings let you pick a refresh mode per app, from a sharp, slower high-definition mode to faster modes that trade clarity for speed. Whichever app you choose, setting it to a balanced mode for writing and switching to the sharp mode for reading makes a noticeable difference.

Obsidian on a Boox: pages that sit still

Obsidian’s unit is the note: one markdown file, shown as one page. When you open a note, the screen draws it once, and while you read it, nothing moves. Reading view, in particular, is close to ideal for e-ink: static, well-spaced text with no editing chrome. Scrolling through a long note is the main source of ghosting, and page-by-page scrolling settings help with that.

Editing is acceptable. Typing in the editor redraws the line you are on and not much else, so a fast refresh mode keeps up with ordinary typing. Live Preview, where formatting renders as you type, does more redrawing than plain source mode, and some people switch to source mode on the tablet for that reason.

The real risk with Obsidian on a Boox is plugins. Every community plugin adds startup time, and some add panels, animations or background work that repaint the screen constantly. A vault that feels fast on a laptop can take a long time to open on a tablet and stutter once it does. The fix is to keep a lean set of plugins on the tablet, and the plugin tax on e-ink is the first thing to deal with if your vault feels sluggish.

Themes matter too. A high-contrast theme with no transparency, no gradients and no animated transitions makes Obsidian look noticeably sharper on e-ink. The popular minimal themes have settings that get you most of the way.

Logseq on a Boox: an outline that never stops moving

Logseq’s unit is the block. Every bullet is its own element, with its own controls for collapsing, referencing and moving. That makes it wonderful for outlining and for dumping thoughts into a daily journal, which is the default page when you open it.

On e-ink, that same structure means more redrawing. Pressing Enter creates a new block, which shifts everything below it. Indenting and outdenting rearrange the outline. Collapsing a section repaints the page. Linked references and queries at the bottom of a page can re-render as you type above them. None of this is slow on a phone. On a Boox, each action is a visible repaint, and after a few minutes of typing the screen collects ghosting faster than with Obsidian.

It is usable. A fast refresh mode, collapsed sections, and turning off visual extras all help. But Logseq asks for more tuning to feel comfortable on e-ink, and it never quite gets to the stillness of an Obsidian note in reading view.

Startup is the other cost. Logseq builds an index of your graph, and on a large graph a tablet’s processor takes noticeably longer than a laptop to do it. If you open the app, jot one line and close it again, that wait is the most annoying part of the day.

Offline and sync: where the real problems live

Both apps store notes as plain markdown files in a folder, which is why they are worth using at all. Your notes are not trapped in a database. But it also means sync is a separate problem, and on a tablet that is often offline, sync is where things go wrong.

Obsidian gives you two good paths. Obsidian Sync, the paid service, is built for the app. It handles conflicts sensibly and syncs settings and plugins too, which helps you keep a lean setup on the tablet. Or you can sync the vault folder yourself with Syncthing, which costs nothing and works well, as long as you set up ignore rules so heavy plugin folders and workspace files do not churn between devices.

Logseq has its own sync service, but it has been slower to mature, and many Logseq users sync the graph folder themselves. Here Logseq is more fragile. It keeps its own state about the graph, and it does not always notice when files change underneath it, for example when Syncthing delivers an edit made on your laptop while the app is open. The safe habit is to let sync finish before opening Logseq on the tablet, and to re-index if something looks out of date.

Whichever app you use, the classic e-ink failure is two devices editing the same daily note while one of them is offline. Both apps end up with a conflict, and how each one resolves it differs. If you write a daily note on both your laptop and your tablet, read about how conflict files appear on e-ink before you trust either setup with a week of travel.

One practical note for Syncthing users: the original Syncthing app for Android was discontinued at the end of 2024. A maintained community fork, Syncthing-Fork, carries on and is what most people now install on a Boox.

Handwriting: neither app, and that is fine

If you bought a Boox for its pen, neither Obsidian nor Logseq will make you happy as a handwriting app. Both have drawing plugins and features, but they are built for mouse and touch, not for a low-latency e-ink stylus.

The setup that works is to keep handwriting in Boox’s own Notes app, which is fast and well tuned for the pen, and export pages as PDF or images into a folder inside your vault or graph. Both Obsidian and Logseq can embed or link those files, so a handwritten page becomes part of your notes without forcing a web app to act like paper.

How they compare day to day

Picking the app for your tablet

Obsidian fits when:

• You mainly read and review notes on the tablet, and write in shorter bursts.
• Your notes are pages and documents rather than outlines.
• You want a sync setup that tolerates the tablet being offline for days.
• You are willing to keep a lean plugin list on the tablet.

Logseq is worth the tuning when:

• You think in outlines, and the daily journal is your main inbox.
• You value block references and queries more than a calm screen.
• Your graph is moderate in size, so indexing stays quick.
• You are happy to tune refresh modes and build a careful sync habit.

If you already use one of them on your laptop, use the same one on the Boox. Switching apps to suit the tablet costs more than any e-ink inconvenience. But if you are starting fresh and the Boox is a big part of how you will read your notes, Obsidian’s still pages suit the screen better. The e-ink tablet rewards apps that draw once and then leave the page alone.
