TL;DR
Apple Notes is sleek but ecosystem-locked, Google Keep is the sticky-note champion for quick thoughts, and OneNote is the Swiss Army knife that does everything but dishes.
You've probably lost countless brilliant ideas to the abyss of your terrible memory. Me too.
That's why note-taking apps aren't just productivity tools—they’re one of the few truly helpful apps on our daily devices.
But with so many options, how do you choose?
I've spent quite some times testing the water, from simple tools to complex powerhouses, from Apple Notes to Notion.
But today, I’ll go over the free most popular free options out there to go with every operating system.
1. Apple Notes:
“The Sophisticated Minimalist”
Remember when Apple Notes was basically digital notepaper where you could jot down grocery lists and nothing else?
Those days are long gone.
Apple Notes has evolved from the app you accidentally opened to a powerful contender that might make you consider buying a $1,200 phone just to use it.
Pros
Apple Notes excels at feeling like it was built into your device rather than tacked on as an afterthought. And it works pretty flawlessly.
The interface is clean without being barren. You can:
Quickly jot down notes with different formatting options, highlights, links, and much more
Scan documents that look like actual scans rather than drunken photography
Create checklists that satisfy that dopamine hit when you check items off
Add hand-drawn sketches if you're blessed with an Apple Pencil and artistic ability
Lock notes with Face ID
But the real magic happens when you're fully committed to the Apple ecosystem. Start a note on your iPhone, continue on your MacBook, review on your iPad, and even check it on your Apple Watch if you hate your eyesight.
Cons
If you're not locked into Apple's walled garden, Apple Notes might get you there. Cross-platform functionality is basically non-existent, which is Apple's way of saying, "Buy our other products or keep your thoughts elsewhere, peasant."

Try the Dark Vision OS icon pack for iPhone*. It looks fantastic!
2. Google Keep:
“The Colorful Sticky-Note Champion”
Using Google Keep feels like walking into an office where someone went wild with Post-it notes, except they're all magically searchable and you'll never find one stuck to the bottom of your shoe.
Pros
Keep is the embodiment of Google's design philosophy: simple, accessible, and slightly addictive. It's the note app for people who think "folders" sound too complicated.
Instead of rigid organization, Keep gives you:
Color-coding that turns your note collection into a digital rainbow
The ability to add collaborators
Voice notes that actually transcribe what you said, not what the AI thought it heard
Location-based reminders that ping you when you're near a place
The best part is how it syncs across anything with a screen and an internet connection. You could probably access Keep on your smart fridge if you were so inclined.
Cons
It’s not complex at all.
Try to write anything longer than a few paragraphs, and the experience becomes about as comfortable as wearing wet jeans.
And if you need serious structure or organization? Keep looks at you blankly and says, "Have you tried using different colors?"
3. Microsoft OneNote:
“The Kitchen Sink Approach”
OneNote is what happens when Microsoft looks at minimalism and says, "No thanks, we'll take ALL the features." Classic Microsoft move.
It's the note app equivalent of bringing a flamethrower to toast marshmallows—excessive but impressive.
Pros
OneNote doesn't just want to be your note app. The feature list reads like a productivity wishlist:
Notebooks, sections, and pages that can be organized with the precision of a librarian with OCD
A canvas approach where you can place text, images, and drawings anywhere you want
The ability to embed practically anything—spreadsheets, PDFs, audio recordings, your existential dread
Handwriting recognition that sometimes feels like witchcraft
Cross-platform availability that works equally well on Windows, Mac, iOS, Android, and probably some platforms that haven't been invented yet
For students and researchers, OneNote is digital nirvana. You can take notes during a lecture, record the audio simultaneously, and later click on your written notes to hear exactly what was being said when you wrote them.
Cons
Learning OneNote's full capabilities requires about the same time commitment as learning Notion, but Notion does offer some unique things.
The interface can feel overwhelming, like walking into a cockpit and being told, "Just fly the plane, it's intuitive."
Let’s be real, Microsoft has never been “good” at design.
OneNote can feel as bloated.
Side-by-Side Comparison
Who Should Use What
Choose Apple Notes if:
You're more committed to Apple than most people are to their marriages
You appreciate thoughtful design and an interface that doesn't shout
You need something powerful but not overwhelming
Your idea of cross-platform is moving from iPhone to iPad
Choose Google Keep if:
Your attention span matches that of a caffeinated squirrel
You need quick capture more than deep organization
You love color-coding everything in your life
You share notes with people who would be confused by anything more complex
Choose Microsoft OneNote if:
You have information management needs that border on professional
Your brain works in an organized, hierarchical way
You teach, study, or research, and need your notes to work as hard as you do
You enjoy spending time learning software (no shade, I'm one of you)
The Bottom Line
After spending way too much time testing notes apps, I've concluded that there's no perfect note app—just the perfect note app for you. Duh…
I've ended up using a combination based on my needs. I mainly use Notion for my complex project organization. But I still use Apple Notes for my personal stuff.
The beauty of digital note-taking is that switching costs are low. Try them all, see which one makes your brain happy.
Obsidian. Plain text, and the notes live on your computer. Sync costs a few bucks, but there are free workarounds. My favorite feature is the daily note where I can dump my brain
