Notion and Unit Notes share a fundamental belief: notes shouldn’t be documents. They should be collections of independent blocks - text, images, checklists, links, recordings - that you can assemble, rearrange, and restructure freely. Both apps are built on this principle.
But they made very different decisions about everything else: who the app is for, what platform it’s native to, how complex it should be, and what features to prioritize. These aren’t minor product differences. They reflect fundamentally different ideas about where and how note-taking happens.
Here’s an honest comparison from people who build one of these apps and use the other.
The single biggest difference between Notion and Unit isn’t a feature - it’s how each app is built.
Notion is a web application. It runs in a browser on desktop and in a web view on mobile. This gives Notion true cross-platform consistency - the experience is nearly identical on Mac, Windows, iOS, and Android. It also means Notion can ship features fast since there’s one codebase to maintain.
Unit is a native iOS application. It’s built in Swift, with a custom data model designed specifically for Apple’s hardware and operating system. This means Unit only runs on iPhone and iPad (with Mac and web planned), but the experience on those devices is qualitatively different from what a web app can deliver.
What does “qualitatively different” mean in practice?
Launch time. Unit opens in under a second. Notion’s iOS app takes noticeably longer to become interactive - especially if it needs to sync or you haven’t opened it recently. This sounds trivial until you’re trying to capture a fleeting thought. A few seconds of loading is enough to lose it.
Block manipulation. Both apps let you drag blocks to rearrange content. In Unit, this uses iOS’s native drag-and-drop system - the same technology that powers rearranging apps on your home screen. The motion is fluid, the feedback is immediate, and there’s no perceptible delay. Notion’s drag and drop works through a web-based gesture handler, which introduces subtle latency. On desktop with a mouse, you might not notice. On a phone with your thumb, you do.
Offline. Unit stores everything locally and works fully offline - create, edit, rearrange, search, everything. Changes sync when connectivity returns. Notion has improved its offline support over the years, but it’s still more limited. Complex pages may not load, some operations require a connection, and the experience can be unpredictable when you’re underground or in the air.
Performance at scale. Unit uses an optimized rendering pipeline that only processes the blocks visible on screen. A note with 500 blocks scrolls as smoothly as one with 5. Notion can slow down noticeably with complex or lengthy pages on mobile, since the web view needs to render and manage a larger DOM.
We’d be dishonest if we didn’t acknowledge where Notion genuinely excels:
Databases. Notion’s database feature - structured tables that can be viewed as lists, boards, calendars, galleries, and timelines - is extraordinarily powerful. You can build project trackers, CRMs, content calendars, and inventory systems. Unit doesn’t have databases. If structured data is central to your workflow, Notion is the right tool.
Relations and rollups. Notion lets you connect databases to each other. A task can link to a project, which links to a client, which links to invoices. This relational model enables complex workflows that no simple note-taking app can replicate.
Team collaboration. Notion was designed for teams from the start. Shared workspaces, permissions, comments, mentions, real-time co-editing - it’s a genuine collaboration platform. Unit is a personal tool. It doesn’t have shared workspaces or multi-user editing.
Cross-platform breadth. Notion works on iOS, Android, Mac, Windows, and the web. Unit is iOS only (Mac and web are planned). If you work across Apple and non-Apple devices, Notion covers all of them today.
Templates and community. Notion’s template gallery and community ecosystem are massive. You can find pre-built systems for almost any workflow. Unit is a simpler tool with less community infrastructure around it.
API and integrations. Notion has a public API and integrates with hundreds of tools through Zapier, Make, and native connectors. Unit currently has no API or third-party integrations.
Unit’s advantages are concentrated in a specific scenario: personal note-taking and knowledge management on iPhone.
Speed. This is Unit’s most tangible advantage. The app is fast - not “fast for a note-taking app” but properly, noticeably fast. It launches instantly, blocks respond to touch without delay, and the interface never stalls or stutters. For something you open dozens of times a day, this adds up. One reviewer captured it well: “I’ve been looking for an app that’s better than notes but not clunky to navigate. Unit manages that.”
Simplicity without sacrifice. Notion’s power comes with complexity. New users face a learning curve: pages vs databases, views, properties, formulas, relations. Unit opens to a clean canvas where you start adding blocks immediately. There’s nothing to configure, no templates to choose from, no views to set up. As one user put it: “It gives you just the right amount of options without overloading and bloating the experience.”
Touch-first editing. Unit’s editing model was designed for fingers, not cursors. The Magic Plus button lets you insert any content type at any point in your canvas with a single tap - you’re not limited to adding content at the cursor position or the end of a page. Multi-select lets you grab several blocks at once for batch operations. Everything is optimized for the ergonomics of one-handed phone use.
Inline voice recordings. Notion doesn’t support voice recordings within pages. Unit lets you record audio directly inline with your other content. The recording sits in context - below the meeting notes it relates to, above the action items it generated. For capturing ideas when typing isn’t practical - walking, driving, cooking - this fills a real gap.
Read-it-later built in. Unit can save entire web pages for offline reading, stored directly inside your notes alongside your own annotations. Notion can embed links and web bookmarks, but it doesn’t save page content locally. URLs break, paywalls appear, pages get deleted - having the actual content saved means your references remain intact.
Visual organization. Unit lets you color-code notes and use nested units (notes within notes) for hierarchical organization. Color is processed faster than text by the visual system, so scanning a color-coded list is meaningfully quicker than reading titles. One user described it as: “Being able to color-code and add tags to each unit so I can sort and filter through them all quickly.”
This comparison isn’t about which app is “better.” It’s about which tradeoffs align with how you work.
Choose Notion if:
Choose Unit if:
Many people use both. Notion for team projects and databases at the desk. Unit Notes for personal capture and organization on the phone. The tools aren’t mutually exclusive - they’re complementary.
The broader point is that “block-based note-taking” isn’t one thing. The same philosophy can produce very different tools depending on the priorities. Notion prioritized breadth, collaboration, and the web. Unit prioritized depth on iOS, speed, and individual use. Both are valid approaches. The right choice depends on where you spend most of your time and what you need your notes to do.
