Go with Apple Notes if you stay on Apple devices and want fast capture with audio transcripts and maths solved as you type. Go with OneNote if you'd rather organise work into notebooks, sections and pages, write anywhere on a free-form canvas, and use it on Windows and Android as well as Apple hardware.
Apple Notes comes with every Apple device, while OneNote is Microsoft's note-taking software, and the gap between them is about structure as much as features. If you carry an iPhone but work on a Windows laptop, or share a household full of mixed devices, what matters is which one will still make sense a year from now.
The canvas changes how you take notes
The biggest difference isn't a feature, it's the shape of the page. OneNote is built around an almost unbounded document window where you click anywhere to add a text box. Information is saved in pages, those pages sit in sections, and the sections live inside notebooks. It's closer to a ring binder with dividers than a stack of separate notes.
Apple's app works note by note. You open a note, type, attach what you need and move on. Neither approach is better in the abstract. A free-form canvas suits people who sketch, lay out meeting notes spatially or keep a single notebook per project. A note-by-note app suits people who capture quickly and search later.
Picture the same meeting in each. On the canvas you might put the agenda top left, a diagram in the middle and the action points in a box beside it, all on one page. In Apple's app the meeting becomes a single flowing note, typed from top to bottom, with the diagram dropped in as an attachment.
Before you compare anything else, ask which of those habits is yours. If you've ever wished you could drop a text box beside a diagram, the canvas will feel like freedom. If you mostly jot and search, it may feel like clutter.
Questions worth asking first
- Which devices will you take notes on in a typical week, and are any of them Windows or Android?
- Do you write notes by hand, or always type?
- Would a password on certain notes give you peace of mind?
- Do you record lectures, interviews or calls you're allowed to record?
- Would an AI summary at the end of a long meeting save you time?
If most of your answers point to mixed devices, handwriting and summaries, OneNote is the stronger candidate. If they point to quick capture on Apple hardware, Apple Notes will be hard to beat.

When Apple Notes is the better fit
If every device you use is made by Apple, the built-in app keeps things simple. Press record inside a note and it captures the audio session and produces a live transcript, which is useful for lectures, calls you're allowed to record, or talking an idea through. Type a calculation, add an equals sign, and the answer appears inline.
Attachments are drag and drop: pictures, videos, PDFs and other files go straight into a note, so a single note can hold a brochure, a photo of a whiteboard and your thoughts on both. For fast, low-effort capture on Apple hardware, it's hard to argue with something that's already installed.
The note-by-note shape also keeps the thinking light. There are no notebooks to plan and no sections to name before you write, so the gap between having a thought and saving it is about as short as it gets.
When OneNote wins
OneNote earns its place when your devices are mixed. It's available as a free, stand-alone app on Windows, macOS, iOS, iPadOS and Android, so you can use the same notebooks on a work PC, an Android tablet and an iPhone.

The notebook structure pays off for long-running work. A notebook per client or course, with a section per month or topic, keeps years of notes browsable in a way a single long list rarely is. The freedom of the canvas is also its risk, though: without a plan, notebooks sprawl and pages end up with names nobody can find six months later, so a little structure on day one saves hours later.
If meeting notes are your main use, also look at other tools that summarise meeting notes, since a clear summary at the end of a long session is the job most people want help with.
Matching the app to the job
- Interviews and lectures belong in Apple's app, because it transcribes the recording live, right inside the note.
- A client project lasting months suits OneNote: one notebook, with a section for each phase.
- Ideas laid out around a diagram suit the OneNote canvas, where a box can go anywhere on the page.
- Trip research full of PDFs, photos and videos suits Apple's app, since files drag straight into a note.
- A work PC plus an Android tablet points to OneNote, which has apps for both.
- A passing thought while you're out is quickest in Apple's app, already on your iPhone.
A week in both apps
Before you move anything, run both for a week on the same work. Take every meeting's notes on the OneNote canvas and every passing thought in Apple's app, then swap for the second half of the week. By Friday you'll know whether the canvas helped you think or just gave you more places to lose things, and whether fast capture was what you were missing all along. Jot down which app you opened first each morning; that small record settles more than any feature list.
Moving your notes without losing anything
- Count what you're moving: how many notes, how many attachments and how many audio recordings.
- Move one folder or one notebook first, never everything at once.
- Open the moved notes on every device you use, including your phone, and check attachments open.
- If you rely on audio transcripts or handwriting, test those on day one, since they're the features most likely to change your routine.
- Set up the structure you want in the new app before importing, so notes land in the right place.
- Leave the originals in place until you've stopped reaching for them, then archive rather than delete.
Frequently asked questions
Is OneNote a separate download on a Mac?
Yes. It's a stand-alone app on macOS, so unlike Apple's built-in app you install it yourself.
Can I put a password on a OneNote note?
Yes. Password protection for notes is one of the features its help pages list.
Can OneNote solve maths like Apple Notes does?
Yes. Microsoft's help lists converting and solving maths equations, so both apps can deal with the sums in your notes.
Can I write by hand in OneNote?
Yes. Handwritten notes are supported, which suits anyone who thinks with a pen or annotates diagrams as they go.
Can Copilot summarise my OneNote notes?
Yes. Microsoft lists Copilot in OneNote, including summarising your notes, so a long page can end with a short recap.
