Notes ABC: Handwriting & PDF

Notes ABC is a private, offline note-taking and PDF workspace made for students, engineers and anyone who thinks best with a pen. Write with real-feeling pens, mark up big textbooks, solve equations without internet, and study smarter. No account needed. Your notes stay on your device.

WRITE LIKE ON PAPER
• Six pens: Fountain, Ballpoint, Pencil, Brush, Calligraphy and Watercolor, plus a Highlighter. Lines follow your hand closely, respond to pressure and keep the size you choose.
• Save your own pens with their own color and width. Add as many as you like and see each one at a glance.
• Precise eraser: remove a whole stroke or just the part you touch. Scribble over a word to erase it without changing tools.
• Realistic paper sound, magnetic baseline snapping and a stylus hover preview of your exact line width.
• Color Studio with ready-made palettes (Everyday, Pastel, Earth) and your own, shown in two scrolling lines for fast access.
• Page rulers in real centimeters, plus a movable ruler and shape recognition.
• Blank, lined, grid, dotted, Cornell and planner paper in A4, A5, Letter and Legal, in light or dark.
• Add photos, stickers, shapes and typed text anywhere, and keep things organized with layers.

BEAUTIFY HANDWRITING
Turn messy writing into clean text as you write. Write, pause, and your words become a beautiful handwriting style or a typed font such as Cursive, Casual, Serif or Mono. Choose Notebook mode to continue line after line from where you start, or In place to tidy each note where you wrote it. Keep your own size or set one. Your original handwriting can be brought back with one tap.

YOUR TOOLBAR, YOUR WAY
Reorder pens and tools by dragging, hide what you do not use, and add new pens. Hold any tool to open its settings. Swipe along the bar to reach everything quickly. Move it anywhere, horizontal or vertical.

STUDY SMARTER
• Active Recall tape: cover labels, formulas and dates, then tap to reveal and test yourself.
• Embed videos next to your notes.
• Pomodoro timer, habit tracker, checklists and mind maps.

MATH, CHEMISTRY AND PHYSICS
• Lasso a formula and solve it step by step, fully offline: equations, derivatives, integrals, limits and matrices.
• 2D graphs and rotatable 3D surfaces you can insert into your notes.
• Balance chemical reactions, find molar masses and convert units.
• Advanced reading for handwritten formulas: use the fast built-in model, or download the more accurate one only if you want it.
• Review what was read and fix it with one tap.

POWERFUL PDF WORKSPACE
• Open and annotate large textbooks with sharp zoom for fine diagrams and small print.
• Long-press to select text, then highlight or underline. Markups stay attached to the page at any zoom.
• Tap links to jump to pages or open web addresses, without clutter on the page.
• Find text across the whole document: jump to each match, with the word highlighted.
• Export notes as vector PDF that stays sharp and searchable in any reader.
• Fill in forms, and add sticky notes, typed text, callouts and stamps.

MOVE AROUND EASILY
• Floating navigator pad to pan across large pages without lifting your pen, with a zoom slider.
• Two fingers pan and zoom, three fingers tap to undo, four to redo.
• Easy Writing Pad: a magnified strip that moves along as you write.
• Split view: keep a reference note beside the one you are writing.
• Night mode keeps late-night study easy on the eyes.

PRIVATE AND SECURE
• No sign-up and no cloud sync. Your notebooks live on your device.
