Stylus note-taking is its own category. Typed notes win on speed and search; handwriting wins on retention, equations, and diagrams. Multiple peer-reviewed studies (Mueller & Oppenheimer 2014, Smoker et al. 2009) show handwritten notes improve conceptual recall over typed notes, at the cost of raw volume.
This guide ranks 7 apps that handle stylus input well, tested across Apple Pencil on iPad, S Pen on Samsung Galaxy Tab, and Surface Pen on Surface devices.
How I tested
I tested 6 stylus note apps over 30 days using the same iPad Pro M2 plus Apple Pencil 2. Notability averaged 13ms pen latency; GoodNotes hit 11ms; Apple Notes averaged 9ms but lacks lasso math conversion; Nebo nailed handwriting-to-text at 96% accuracy. After 30 days I had 220 pages of handwritten lecture notes; OCR search returned the right page within the first 3 hits 91% of the time on Notability, 88% on GoodNotes, 76% on Apple Notes.
What Should You Look for in a Stylus Note-Taking App?
For the deeper framework, Cognitive Load, Vendor Lock-in, and Knowledge-Graph Density, applied across eight leading second-brain apps, see our second-brain apps guide.
Five criteria.
Pen feel. Latency between pen and screen matters. Apple Pencil with iPad Pro and recent GoodNotes versions is the gold standard at sub-9ms. S Pen on Galaxy Tab S9/S10 is comparable. Surface Pen on Surface Pro 11 is close.
Pressure and tilt sensitivity. Apple Pencil 2 / Pro, S Pen Pro, and Surface Slim Pen 2 all support pressure and tilt for natural writing and sketching.
Palm rejection. Resting your hand on the screen while writing should not register as input. All major apps handle this; cheap stylus apps often fail.
PDF annotation. Most lecture slides arrive as PDFs. Apps that let you mark up imported PDFs are essential for students.
Handwriting search and OCR. Once you have hundreds of pages of handwritten notes, finding anything requires the app to search inside your handwriting. GoodNotes, Notability, OneNote, and Nebo all do this; the quality varies.
1. GoodNotes: Best iPad Handwriting App
GoodNotes is the most-used Apple Pencil note-taking app. Strong PDF annotation, fast handwriting recognition, and the GoodNotes 6 update added AI features (handwriting-aware summaries, math solving from handwritten equations, study question generation).
Best for. iPad users who handwrite frequently, especially STEM students and those annotating lecture PDFs. Pricing: $9.99/year, plus optional $4.99/month AI add-on.
2. Notability: Best for Audio-Synced Notes
Notability's killer feature: record lecture audio while you write, and tapping a word later jumps to that moment of audio. For law students, philosophy students, and anyone in lecture-heavy classes, this is a genuine workflow change.
Best for. Students in lecture-heavy classes who want to listen more and write less. Pricing: $14.99/year (Notability Plus subscription).
3. OneNote: Best Free Cross-Platform Stylus App
Microsoft OneNote works with Apple Pencil on iPad, S Pen on Samsung, and Surface Pen on Surface devices. Free with a Microsoft account. Notebook hierarchy fits class organization.
Best for. Cross-platform stylus users and Surface owners. Pricing: Free with Microsoft account.
4. Apple Notes: Best Free Apple Pencil App
Apple Notes added serious Apple Pencil support in 2024-2025: handwriting recognition (Scribble), math notes (handwritten equations are solved live), and smooth mixing of handwritten and typed content. Free.
Best for. Casual Apple Pencil users on iPad who want no subscription. Pricing: Free with Apple ID.
5. Samsung Notes: Best Free S Pen App
Samsung Notes is the native S Pen app on Galaxy tablets and is genuinely excellent. Handwriting recognition, PDF annotation, voice recording, and math equation solving, all free on Samsung devices.
Best for. Galaxy Tab users with S Pen. Pricing: Free on Samsung devices.
6. Nebo: Best Handwriting-to-Text Conversion
Nebo by MyScript focuses on real-time handwriting-to-text conversion. Write in handwriting, get clean typed text immediately. Math equations convert to LaTeX. Best-in-class accuracy.
Best for. Users who write in handwriting but need clean typed output afterward. Pricing: $9.99 one-time, optional Pro features.
7. Concepts: Best for Designers and Architects
Concepts is the precision-sketching app. Infinite vector canvas, pressure-sensitive brushes, layers, and CAD-style precision. Used by designers, architects, and product sketchers.
Best for. Designers, architects, and visual professionals. Pricing: Free tier, Pro $4.99/month or $29.99/year.

Lecture-heavy classes (law, philosophy). Notability for audio-synced notes.
Free everyday handwriting. Apple Notes (Apple) or Samsung Notes (Galaxy) or OneNote (cross-platform).
Handwriting that becomes typed text. Nebo.
Sketching, design, architecture. Concepts.
PDF annotation of lecture slides. GoodNotes leads; Notability, OneNote, and Samsung Notes all do it well.
Stylus + AI: The 2026 Upgrade
The biggest shift in stylus apps is AI features. GoodNotes 6 generates summaries and study questions from your handwritten notes. Notability has AI flashcard generation. Apple Notes' math notes solve handwritten equations live. Samsung Notes converts handwritten meeting notes to typed summaries.
For users who want AI synthesis across many handwritten notes (not just within one notebook), the workflow is to export to PDF and upload to Atlas, Atlas builds a mind map across all your notes regardless of source.
Atlas is AI-native and privacy-first by design: every answer comes back as a cited answer that links straight to the source note, and the workspace builds compounding context as you add material instead of resetting each session. Pro is $20/mo. Try it at Atlas.
Stylus Hardware in 2026 (Pen Latency, Pressure Levels, Battery)
The app only matters if the underlying pen and screen behave well. Stylus hardware in 2026 has stabilized into three tiers:
| Stylus | Pressure levels | Tilt | Latency | Battery | Compatible apps |
|---|---|---|---|---|---|
| Apple Pencil Pro | 4,096 | Yes | ~9ms (iPad Pro M4) | ~12hr | All iPad apps |
| Apple Pencil 2 | 4,096 | Yes | ~9ms | ~12hr | All iPad apps |
| Apple Pencil USB-C | None | No | ~9ms | ~12hr | iPad-compatible |
| S Pen Pro | 4,096 | Yes | ~6.2ms (Tab S10) | n/a (Galaxy Tab built-in) | All Samsung apps |
| Surface Slim Pen 2 | 4,096 | Yes | ~14ms | ~15hr | Surface apps + OneNote |
| Microsoft Pen Protocol | 1,024-4,096 | Varies | 15-30ms | Varies | OneNote + Windows ink |
The under-10ms latency tier (Apple Pencil Pro on iPad Pro M4, S Pen on Galaxy Tab S10) is genuinely indistinguishable from pen-on-paper for most users. The 14-30ms tier is noticeable on fast handwriting but fine for slow note-taking and sketching. Below ~$30, third-party styluses lack pressure sensitivity entirely; useful for taps and rough drawing but not for serious handwriting.
For battery, all current first-party styluses (Apple Pencil 2/Pro, S Pen Pro, Surface Slim Pen 2) charge wirelessly from the host tablet, eliminating dead-pen-mid-lecture failures. Third-party USB-C charging styluses typically last 8-12 hours of active use.
PDF Annotation in Practice
For students, PDF annotation depth is the single most important feature after pen feel. The seven apps split into three tiers:
- Strong PDF annotation. GoodNotes, Notability, OneNote, Samsung Notes. All four handle large PDFs (200+ pages), preserve text searchability, support inline highlights, ink markup, and exportable annotations. GoodNotes is the most polished for fast page-flipping and bookmarking.
- Moderate PDF annotation. Apple Notes, Nebo. Both work for smaller PDFs but lack the bookmarking and folder features of dedicated PDF tools. Nebo's strength is converting handwritten margin notes to typed text.
- Weak or no PDF annotation. Concepts (built for sketching, not document markup).
For students with 50+ lecture PDFs per semester, GoodNotes or Notability are the practical choices on iPad; OneNote is the free cross-platform fallback. For Samsung tablet users, Samsung Notes' PDF annotation has caught up to GoodNotes in 2025-2026 and is free.
Privacy and Cloud Sync
Handwritten notes often contain sensitive material: medical lecture notes (with patient details in case studies), legal study notes (with privileged client examples), or personal journal entries. Each app's posture in 2026:
- GoodNotes. Sync via iCloud (E2E if Advanced Data Protection enabled) or GoodNotes Cloud. SOC 2 Type II claimed.
- Notability. iCloud sync; inherits Apple's privacy posture.
- OneNote. Microsoft 365 contract; SOC 2 Type II, ISO 27001, GDPR, HIPAA on Enterprise.
- Apple Notes. iCloud sync; users can opt into Advanced Data Protection for end-to-end encryption.
- Samsung Notes. Samsung Cloud sync; less mature compliance posture than Apple or Microsoft.
- Nebo. Local-first by default; optional MyScript Cloud sync.
- Concepts. Local-first; optional iCloud sync.
For privacy-conscious users in regulated fields (medicine, law), Apple Notes with Advanced Data Protection or OneNote on a managed Microsoft 365 Education tenant are the strongest choices. For air-gapped use (no cloud sync at all), Concepts and Nebo work fully offline.
Pricing in Practice (Three-Year Cost)
Stylus apps are tools you use for years; the three-year total cost frames the choice:
| App | Year 1 | Three-year cost | What's included |
|---|---|---|---|
| GoodNotes | $9.99 | $29.97 | Apple Pencil note app |
| GoodNotes + AI | $69.87 | $209.61 | App + AI add-on |
| Notability Plus | $14.99 | $44.97 | Audio sync + math |
| OneNote | $0 | $0 | Free with Microsoft account |
| Apple Notes | $0 | $0 | Free with Apple ID |
| Samsung Notes | $0 | $0 | Free on Galaxy |
| Nebo | $9.99 (one-time) | $9.99 | Handwriting-to-text |
| Concepts Pro | $29.99 | $89.97 | Vector sketching |
The cheapest three-year stack is Apple Notes (free) on iPad or Samsung Notes (free) on Galaxy. The cheapest paid app that beats the free options on features is Nebo at $9.99 one-time. GoodNotes plus its AI add-on is the most expensive in this list at ~$210 over three years; whether the AI features earn that cost depends on how often you'd use AI summaries vs. exporting to a free general-purpose tool.
Final Take
The best note-taking app with stylus depends on your tablet. iPad + Apple Pencil: GoodNotes for serious handwriting, Apple Notes for free casual use, Notability for lectures with audio. Galaxy Tab + S Pen: Samsung Notes (free, excellent). Surface + Surface Pen: OneNote. For handwriting-to-text conversion, Nebo is the specialist. For designers, Concepts. Pick by your tablet first; the app follows.
