Best Note-Taking App with Stylus in 2026: A Head-to-Head Comparison by Performance and Platform

Introduction: Why Stylus Performance Matters More Than Ever

The gap between writing on paper and writing on a screen has narrowed to the point where, with the right app, you can forget you are not using a physical notebook. But that experience depends entirely on a handful of technical details that most app store descriptions gloss over: stylus latency, palm rejection quality, and handwriting recognition accuracy. A difference of a few milliseconds in latency or a few percentage points in recognition accuracy can mean the difference between a tool that fades into the background and one that constantly reminds you it is there.

This comparison is built around those specific performance metrics. It is not a general device-buying guide — we have already covered that angle in our Handwritten Notes App Buying Guide 2026, which organizes recommendations by device ecosystem. Here, we focus on concrete, measurable differences in stylus behavior across eight apps: Samsung Notes, Nebo AI 4.0 (now MyScript Notes), GoodNotes 6, Notability, Microsoft OneNote, Noteshelf, Flexcil 3 Pro, and Apple Notes. We also include apps like Noteshelf and Flexcil 3 Pro that were not covered in our earlier guide, because they bring meaningful strengths to specific workflows.

How We Evaluated and Compared These Apps

The core performance data in this comparison — latency measurements, handwriting recognition accuracy percentages, and annotation time reductions — comes from independent testing conducted by ROIpad between May 2025 and January 2026. Their testing involved 450+ hours across 15 Android tablet models with 8 active stylus technologies, plus controlled tests on iPad and Windows devices. The handwriting recognition accuracy figures are based on 15,000 handwriting samples across 12 languages from 75 test subjects.

We supplemented this with hands-on evaluations from Tool Finder, MakeUseOf, ZDNET, and PCMag, and cross-referenced pricing data against current app store listings as of June 2026. The evaluation criteria are:

• Stylus latency: the delay between pen tip contact and ink appearing on screen, measured in milliseconds. Lower is better.
• Handwriting recognition accuracy: the percentage of handwritten words correctly converted to typed text in controlled tests.
• Palm rejection quality: how reliably the app ignores accidental palm contact while writing.
• PDF annotation: the depth of tools for marking up, highlighting, and organizing PDF documents.
• AI features: built-in capabilities like handwriting-to-text conversion, math solving, summarization, and quiz generation.
• Cross-platform availability: whether the app works across iOS, Android, Windows, and macOS, and how well the experience transfers between platforms.

Deep Dive: The Top Contenders for Stylus Note-Taking

Samsung Notes 2026: The Gold Standard for Galaxy Tab Owners

If you own a Galaxy Tab S10 series device with the S Pen Pro 2, Samsung Notes is the most responsive stylus note-taking app available. ROIpad's testing measured latency at just 6ms — the lowest of any app in this comparison — and handwriting recognition accuracy at 97.3%. The app is pre-installed and free, with no subscription required.

The deep integration with Samsung's hardware means palm rejection is essentially flawless: the device knows when the S Pen is near and ignores hand contact. The app also achieves a 99.7% sync success rate across Galaxy devices, per ROIpad, so your notes stay consistent if you use multiple Samsung products.

• Best for:Galaxy Tab S10 owners who want the lowest latency and best palm rejection available.
• Not for you if:You use an iPad, non-Samsung Android tablet, or Windows device. Samsung Notes is locked to the Galaxy ecosystem.
• Caveat:The 6ms latency and 97.3% accuracy figures are specific to the Galaxy Tab S10 series with S Pen Pro 2. Older Galaxy devices will not achieve the same performance.

Nebo AI 4.0 (MyScript Notes): The Cross-Platform Handwriting Recognition Champion

Nebo, now rebranded as MyScript Notes in late 2025, holds the highest handwriting-to-text conversion accuracy in this comparison at 98.1%, based on ROIpad's 15,000-sample test across 12 languages. More impressively, it achieved a consistent 9ms latency across 12 different Android tablet models from 5 manufacturers — meaning the experience does not degrade on non-Samsung hardware.

The app's AI features go beyond simple conversion. It can summarize handwritten notes, explain concepts, generate quizzes, and solve math equations. The Lasso tool lets you select, move, and resize handwritten content as if it were typed text. MakeUseOf's testing highlighted that Nebo's handwriting recognition "achieves a level of accuracy that no other app on Android matches."

Nebo is available on iOS, Android, Windows, and macOS, making it the strongest cross-platform option for users who switch between devices. The free version limits you to 5 notes; the full unlock is a one-time payment of $14.99 (legacy pricing) or a subscription at $8.99/month or $59.99/year.

• Best for:Users who prioritize handwriting-to-text conversion accuracy above all else, and those who work across multiple platforms.
• Not for you if:You need deep PDF annotation tools or a rich notebook organization system. Nebo's PDF support is basic.

GoodNotes 6: The iPad-First Powerhouse with Growing Cross-Platform Reach

GoodNotes 6 remains the most polished stylus note-taking experience on iPad. The writing feel is paper-like, palm rejection is excellent, and the AI features — including Ask GoodNotes, which can explain concepts from your handwritten notes — add real utility. Tool Finder named it the "best all-rounder for iPad" in their 2026 testing.

The app has expanded to Android and Windows, but the experience on those platforms still trails iOS. The Android version improved in 2026, but latency is slightly higher and palm rejection is less reliable than on iPad. If you are primarily an iPad user, GoodNotes is an easy choice. If you need to switch between iPad and a Windows laptop, the cross-platform experience is functional but not seamless.

Pricing has shifted to a subscription model: $9.99/year or $29.99 lifetime on iPad, or $11.99/year for the cross-platform plan. A free starter plan with 3 notebooks is available. For a detailed look at GoodNotes on Windows, see our GoodNotes for Windows guide.

• Best for:iPad users who want the most refined writing experience and AI-powered note review.
• Not for you if:You are on Android or Windows and expect the same level of polish as the iPad version.

Notability: The Lecture Capture Specialist

Notability's standout feature is its audio recording with real-time transcription. As you write, the app records the lecture or meeting and syncs the audio to your handwritten notes. Tap on any word later, and the audio jumps to that moment. For students and meeting-heavy professionals, this is a killer feature that no other app in this comparison matches as cleanly.

ZDNET rates Notability 4.7 stars alongside GoodNotes, noting its multiple pen styles, PDF annotation, templates, and math conversion. However, the app is Apple-only — there is no Android or Windows version. Pricing is $14.99/year for Standard (unlimited edits, handwriting search, iCloud sync) or $19.99/year for Plus (adds AI tools). There is no one-time purchase option.

• Best for:Students and professionals who need audio-synced handwritten notes for lectures or meetings.
• Not for you if:You use Android or Windows, or you want a one-time purchase option.

Microsoft OneNote: The Best Free Cross-Platform Option

OneNote is the only app in this comparison that offers a genuinely free, full-featured stylus experience across iOS, Android, Windows, and macOS. PCMag gives it 4.5 out of 5 stars and an Editors' Choice award, citing its excellent organization tools, free-form placement of content, and top-notch web clipper.

The trade-off is performance. ROIpad measured OneNote's latency at 12ms on Android — double Samsung Notes' 6ms — and handwriting recognition accuracy at 94.7%. Palm rejection is good but not excellent, and the app lacks the AI-powered features of Nebo or GoodNotes. For casual note-taking and cross-platform access, OneNote is hard to beat at its price point. For power users who write extensively, the higher latency and lower accuracy may become noticeable.

• Best for:Budget-conscious users who need stylus support on multiple platforms without paying for a subscription.
• Not for you if:You need the lowest possible latency, best handwriting recognition accuracy, or advanced AI features.

Noteshelf: The Best Android Stylus Experience Outside Samsung's Wall

For Android tablet users who do not own a Galaxy Tab, Noteshelf offers the strongest stylus experience. Tool Finder highlights it as the best Android option with a $9.99 one-time purchase, AI features, and reliable palm rejection across Android devices. ROIpad's testing measured 93.2% handwriting recognition accuracy and 10ms latency — not class-leading, but solid for a non-Samsung-optimized app.

Noteshelf is available on iOS, Android, Windows, and macOS, making it a viable cross-platform option. The one-time purchase pricing is increasingly rare in this category and may appeal to users who are tired of subscriptions.

• Best for:Android tablet users (non-Samsung) who want a one-time purchase app with good stylus support.
• Not for you if:You need the highest handwriting recognition accuracy or advanced PDF annotation tools.

Flexcil 3 Pro: The PDF Annotation Speed Demon

Flexcil 3 Pro is purpose-built for users who spend most of their note-taking time annotating PDFs. ROIpad's testing found that it reduces common annotation task times by 62% compared to other apps, thanks to its unique split-screen and drag-and-drop workflow. You can pull content from a PDF directly into a side notebook without switching modes.

Its handwriting recognition accuracy is 95.8% with 8ms latency, per ROIpad — competitive with the top tier. The app is available on iOS and Android, with pricing at $7.99/month or $49.99/year. If your workflow is PDF-heavy — research papers, contracts, technical documents — Flexcil's efficiency gains may justify the subscription cost.

• Best for:Researchers, lawyers, and professionals who annotate large volumes of PDFs.
• Not for you if:You primarily take freeform handwritten notes and rarely work with PDFs.

Apple Notes: The Surprising Free Contender

Apple Notes has evolved significantly with iPadOS 18. The Smart Script feature refines your handwriting to make it more legible without changing your personal style, and Math Notes solves handwritten equations in real time. Handwritten content is fully searchable via iCloud, and the app is free and built into every Apple device.

ZDNET rates Apple Notes 4.6 stars, noting its seamless iCloud sync and searchable handwritten content. Latency with Apple Pencil on an iPad Pro is approximately 7ms — among the best available. The limitations are minimal PDF annotation tools and no cross-platform support. If you are fully in the Apple ecosystem and your needs are straightforward, Apple Notes may be all you need.

• Best for:Apple-only users who want a free, built-in app with excellent handwriting refinement and search.
• Not for you if:You need cross-platform access, advanced PDF annotation, or AI-powered note features beyond math solving.

Best-for Summary: Which App Should You Choose?

The right app depends on your device, your primary workflow, and your budget. Here is a quick-reference guide to the best choice for each common scenario.

• Best for Galaxy Tab S10 owners: Samsung Notes. The 6ms latency and 97.3% accuracy are unmatched on Samsung hardware, and it is free.
• Best cross-platform handwriting recognition: Nebo AI 4.0 (MyScript Notes). 98.1% accuracy across iOS, Android, Windows, and macOS makes it the clear leader for users who switch devices.
• Best for iPad: GoodNotes 6. The most polished iPad stylus experience with strong AI features and a reasonable $9.99/year subscription.
• Best for students (iPad): Notability. Audio-synced handwriting is a game-changer for lecture capture, though it is Apple-only.

• Best for non-Samsung Android tablets: Noteshelf. A one-time $9.99 purchase with good stylus support and cross-platform availability.
• Best for PDF-heavy workflows: Flexcil 3 Pro. 62% faster annotation times make it the efficiency leader for document-intensive work.
• Best free Apple-only option: Apple Notes. Smart Script and Math Notes make it surprisingly capable for a built-in app.

Frequently Asked Questions About Stylus Note-Taking Apps

Can I sync my handwritten notes across platforms?

It depends on the app. OneNote syncs seamlessly across iOS, Android, Windows, and macOS via Microsoft's cloud. Nebo AI 4.0 also supports cross-platform sync through its own cloud. GoodNotes 6 offers cross-platform sync but the experience is smoother within the Apple ecosystem. Samsung Notes syncs across Galaxy devices but not to iPad or Windows natively. Apple Notes syncs only within the Apple ecosystem via iCloud.

How accurate is handwriting-to-text conversion in 2026?

The best apps now achieve 95-98% accuracy in controlled conditions. Nebo AI 4.0 leads at 98.1%, followed by Samsung Notes at 97.3% and Flexcil 3 Pro at 95.8%, per ROIpad testing. Accuracy varies by language, handwriting style, and writing speed. For a broader look at handwriting-to-text tools beyond stylus apps, see our Handwriting-to-Text Apps Compared guide.

Is a paid app worth it over a free one like OneNote?

For casual note-taking, OneNote's free offering is sufficient. The trade-offs are higher latency (12ms vs. 6-9ms for paid apps), lower handwriting recognition accuracy (94.7% vs. 97-98%), and fewer AI features. If you write extensively, annotate PDFs regularly, or rely on handwriting-to-text conversion, the paid apps deliver a noticeably better experience. The $10-15/year subscription for GoodNotes or Notability is a small investment for daily use.

Do I need a specific stylus for these apps?

All the apps in this comparison work with any active stylus compatible with your device. However, performance varies significantly. ROIpad found that apps optimized for the S Pen showed 34% better latency and 41% improved accuracy compared to generic stylus support. If you are using a third-party stylus on an Android tablet, Nebo AI 4.0's consistent 9ms latency across 12 different tablet models makes it a safer bet than Samsung Notes, which is tuned specifically for the S Pen.

What about apps like CollaNote, Noteful, or LiquidText?

These are worthy contenders that did not make the top tier of this comparison due to limited testing data or narrower use cases. CollaNote offers built-in translation over 90 languages and a free unlimited-note tier. Noteful (iPad-only) is a strong PDF annotation app with a one-time purchase under $15. LiquidText is the best option for deep document analysis and research, with an $80 one-time purchase or subscription. If your workflow is highly specialized, these apps are worth investigating.
