Apple Notes vs. OneNote vs. Google Keep: Pick the Right Free iPad Note-Taking App

Yes, you can take notes on an iPad without paying anything. The harder part is avoiding the “free” app that quietly becomes a paid app after a few notebooks, a semester of PDFs, or a small number of monthly edits. For this comparison, “free” means the core app is usable without a subscription wall: Apple Notes, Microsoft OneNote, and Google Keep.

That leaves out some very good tools on purpose. GoodNotes, Notability, and CollaNote can be better choices if your real priority is polished handwriting, PDF markup, or advanced annotation. But their free tiers or optional paid upgrades are a different question from “Which free note taking apps for iPad can I rely on without planning around an upgrade?” GoodNotes’ free tier has been reported with a three-notebook limit, Notability’s free plan with limited edits per month, and CollaNote with an optional premium unlock; those details are useful, but they make these apps freemium rather than the center of this comparison.[1]

Quick Verdict

• Pick Apple Notes if your notes mostly live on iPhone, iPad, and Mac, and you want the fastest no-setup capture.
• Pick OneNote if you handwrite seriously, use Windows or Android too, or need notebooks, sections, pages, audio, and a larger structure that survives across devices.
• Pick Google Keep if you want quick reminders, voice notes, shared lists, and Google-side capture more than a notebook replacement.
• Skip all three as your main app if your main work is heavy PDF annotation, pen customization, or a handwriting-first study system.

Apple Notes vs. OneNote vs. Google Keep

The table is doing most of the honest work here. These apps are not three versions of the same product. Apple Notes is a built-in capture system. OneNote is a cross-platform notebook. Google Keep is a fast note-and-reminder layer sitting beside the rest of Google Workspace.

Pick Apple Notes If Your Life Is Already Apple-Shaped

Apple Notes is the free iPad note app I would rather see most Apple-only users start with before they download anything else. It is already installed, it does not ask them to invent a notebook system on day one, and it is available wherever their Apple life already happens: the iPad on the couch, the iPhone at the grocery store, the Mac during work.

Its biggest advantage is not that it looks exciting. It is that capture has almost no ceremony. Quick Notes can be opened with an Apple Pencil gesture from the bottom-right corner of the iPad screen, which matters when the choice is not between Apple Notes and a prettier app, but between writing the thing down now and forgetting it by the time an app finishes asking where to file it.[2]

It has also grown past the old “plain yellow notepad” reputation. Recent iPad note-taking coverage highlights native handwriting support, Apple Pencil Scribble, search that can find handwritten content, smart folders, collapsible sections, math notes that can solve or plot inline, and Apple Intelligence summarization features in iOS 18 and iPadOS 18.[2]

There are practical comforts here too: locked notes with Face ID or Touch ID, shared notes and folders, scanned documents, checklists, tags, and smart folders. For someone managing family lists, meeting notes, travel plans, class reminders, recipes, and stray ideas, that is enough structure without turning the app into a second job.

The catch is the Apple border. Apple Notes has no native Windows or Android app. You can use iCloud on the web from other platforms, but that is not the same as having a proper app on a Windows laptop or Android phone. If you regularly move between an iPad and a Windows machine, this is not a minor inconvenience; it is the point where a free app starts charging you in friction.

The other catch is hardware. Apple Intelligence features require an M1 or later iPad, or an iPad mini with A17 Pro. If you have an older iPad, Apple Notes can still be a very good free notes app, but it should not be sold to you as if every new AI feature will appear on your device.

Where Apple Notes Fits Best

• You use an iPhone, iPad, and Mac as your main devices.
• You want fast capture more than a carefully designed notebook system.
• You handwrite sometimes, but do not need advanced pen presets or PDF-heavy annotation.
• You want private notes that can be locked with Face ID or Touch ID.
• You are willing to accept that Windows and Android access will be second-class.

Pick OneNote If Your Notes Need to Survive Outside Apple

OneNote is the app I recommend to people who do not live inside one ecosystem. It is not the most elegant iPad note-taking app, and its notebook-section-page model can feel old-fashioned beside newer tools. But if your week includes an iPad, a Windows laptop, a work Mac, and maybe an Android phone, old-fashioned can be a compliment when it means the notes are still there.

ZDNET identified OneNote as a free iPad note-taking option with no credit card requirement, no notebook cap, and no note limit, while noting the 5 GB free OneDrive storage limit shared across Microsoft services.[3] That distinction matters. A missing notebook cap feels generous until the storage meter starts moving; for text notes, meeting notes, and moderate handwriting, 5 GB can last a while, but imported PDFs, image-heavy pages, and years of inked notebooks can make the ceiling arrive sooner than expected.

The iPad experience is strongest when you treat OneNote like a freeform workspace rather than a stack of paper. Its infinite canvas lets you tap, type, draw, diagram, or drop content wherever it makes sense. That is useful for lecture notes that sprawl sideways, project planning that starts as a cluster of boxes, and meeting notes where typed decisions sit beside hand-drawn process sketches.

For Apple Pencil users, OneNote is the serious free alternative in this group. ZDNET notes Apple Pencil support and an Ink Color Selector tool that lets users choose pen color mid-stroke.[3] It is not trying to be a boutique handwriting studio, but it does offer native ink in a way Google Keep simply does not.

Audio is another reason OneNote deserves more respect than its interface sometimes earns. Audio recording can sync to typed or inked notes, so playback can jump to the part of the note associated with what was being said at the time.[3] For a student, interviewer, or meeting-heavy worker, that can matter more than whether the sidebar looks modern.

The organization model is also the most durable of the three apps. Notebooks, sections, and pages make sense for semesters, clients, departments, research projects, or long-running personal systems. Apple Notes can approximate some of this with folders and smart folders, but OneNote is better when the structure has to be visible and stable.

The trade-off is that OneNote asks for more tolerance. Sync depends on OneDrive, storage is shared, the interface can feel dense, and imported PDFs can turn a “free forever” setup into a storage-management problem. If you are going to annotate hundreds of large PDFs, you should think about storage before you build a whole study system inside it.

Where OneNote Fits Best

• You use an iPad plus Windows, Android, Mac, or the web.
• You want real Apple Pencil handwriting without paying for a handwriting-first app.
• You organize by class, project, client, department, or long-running topic.
• You record lectures, interviews, or meetings and want audio tied to notes.
• You can watch the 5 GB OneDrive storage ceiling before PDFs and media pile up.

Pick Google Keep If You Need Capture, Not a Notebook

Google Keep is excellent when it is allowed to be Google Keep. It is a fast place to catch a thought, dictate a note, save a list, set a reminder, color-code a small pile of active items, or share a grocery list with another Google user. It becomes disappointing only when someone tries to sell it as a full iPad handwriting app.

Its strength is the Google surface area. Keep connects with Gmail, Google Docs, and Google Calendar reminders; it also supports voice notes with auto-transcription on iPad, labels, color coding, and collaborative notes.[2] If your day already runs through Gmail and Docs, Keep can be the small capture layer that keeps ideas from disappearing before they become documents, tasks, or calendar reminders.

The storage number looks more comfortable than OneNote on paper: Google accounts include 15 GB of free storage shared across Gmail, Drive, and Photos.[2] But Keep’s real limitation is not usually storage. It is shape. There are no notebooks, no section hierarchy, no serious long-form workspace, no robust PDF markup, and no native Apple Pencil inking experience comparable to Apple Notes or OneNote.

That makes Keep a poor answer for the student who wants to handwrite lecture notes across a semester. It is a good answer for the same student’s parking reminders, office-hour questions, shared shopping list, or sudden idea that should later become a Google Doc. The difference sounds small until the week before exams, when a wall of colored cards is not the same thing as a course notebook.

Where Google Keep Fits Best

• You use Gmail, Google Docs, and Google Calendar all day.
• You want fast notes, reminders, shared lists, and voice capture.
• You prefer labels and search over folders and notebooks.
• You do not need Apple Pencil handwriting as your main use.
• You expect short notes to move elsewhere when they become real documents.

The Limitations That Change the Answer

The right free iPad notes app usually becomes obvious once you name the constraint you are most likely to hit.

This is also where the freemium handwriting apps deserve a fair mention. Dedicated tools such as CollaNote, GoodNotes, and Notability are often better for people who care deeply about pen tools, handwriting recognition, PDF markup, stickers, templates, or study-focused annotation systems. Handwriting-focused comparisons regularly treat these apps as a different class from general-purpose note apps.[4]

Paying for that class of app can be reasonable. The mistake is pretending it is the same decision as choosing a genuinely free default notes app. If your work depends on polished handwritten notebooks and marked-up PDFs, start by comparing handwriting apps. If your work depends on notes being available everywhere without a surprise subscription, start with Apple Notes, OneNote, and Google Keep.

The Clean Match

For an Apple-only iPad owner, Apple Notes is the safest free starting point: instant capture, strong enough handwriting, locked notes, smart organization, and no extra account to manage. For anyone who uses Windows, Android, or a mixed-device setup, OneNote is the better free bet, especially if handwriting, audio, and structured notebooks matter. For a Google-heavy routine, Google Keep is the right quick-capture tool, as long as you do not mistake it for a full notebook app.
