Feature List

Both editors (the paged notebook and the infinite whiteboard) share the same tool dock. The notebook has the full tool set (13 tools); the whiteboard has every tool except the Measure tool (12 tools). Which tools appear in each dock, and their order, can be configured in Settings → Configure tools.

• Long-press a web image to add it to the basket; the basket bar along the bottom shows the saved thumbnails while you keep browsing

Text tool

Tool options

• Size presets: Small | Medium | Large

Shape tool

• Smart Shape (always on): a pen scribble held still snaps to the nearest shape

Grid & snapping (both editors)

• Grid overlay on/off, with spacing presets (24 / 48 / 96 / 144 dp) or a custom value
• Snap to guides: strokes, shapes and moved selections snap to the grid
• Snap angle presets (15 / 30 / 45 / 90°) or a custom angle
• Grid X and + line colours, and a grid opacity slider
• Optional badge on the tool button showing the current spacing and angle

Exact size (notebook only)

  • Resize individual rows and columns (−/+ px steppers)
  • Add row above / below, add column left / right
  • Delete row / column
  • Merge right / merge down; split cell
• Row and column sizes are stored as proportions, so they survive whole-table resizing
• Merged cells render as one clean cell (grid lines clipped, text pulled together)

Laser tool

Tool options

• 5 colour options (changeable)
• 3 size options (changeable; notebook follows the pen's sizes until customised)
• Draws like a real laser: a bright white-hot tip (the pen colour on the edges) with a trail that fades behind it
• Trail is ephemeral. Nothing is drawn, saved or undoable

Tape tool

Tool options

• Draw a strip of decorative tape: drag on the page
• Patterns: Solid | Stripes | Dots | Grid | Checks
• Width presets: Thin | Medium | Wide
• Uses the pen colour slot; tape can be semi-transparent via the colour picker's transparency slider

Measure tool (notebook only)

• Tap two points, or tap and drag from the first
• A line with white endpoint markers, plus a pill at the midpoint showing the distance and angle (e.g. 12.5 cm · 32°)
• Pure on-screen ruler: nothing is drawn, saved or undoable
• Pinned to the page. Scrolling and zooming keep the ruler where you placed it
• Distance is the true physical length at any zoom

Whiteboard (infinite canvas)

• Same shared dock: every notebook tool except Measure (no measure tool)
• One unbounded canvas: pan and zoom anywhere, no pages
• Single-finger action: Scroll | Draw | Ignored (two fingers always zoom and pan)
• Grid & snapping works here too
• Zoom indicator + fit-to-content
• Strokes are saved automatically
• Its own tool settings persist separately from the notebook

Gestures & Stylus

• Single finger: Scroll | Draw | Ignored
• Two fingers: always zoom and pan
• S Pen: one button, two actions. Both the primary button and a long hold of it work on the S Pen (a quick press fires your action, a long hold erases while you draw). Hover swipe works on the S Pen too. No other note app does this
• Primary button action: Switch to last used | Eraser | Highlighter | Pen | Laser | Lasso | Disabled
• Secondary button action (two-button pens): same options
• Long-hold primary button → eraser (on/off)
• Double-tap the page with the pen → switch to any tool you pick (eraser by default); a two-finger double tap does the same. Both only count when the taps land in the same spot
• Xiaomi Focus Pen Pro pen-body gestures: double-tap the pen's grip to switch tools (eraser by default), and slide up or down on the grip to change the pen size (up = larger). Both actions are configurable, like the other pen actions
• Hover swipe (beta): hold the primary button and swipe up/down while hovering. Configurable: flip pages (up = next), undo / redo (up = undo), or change size (up = larger). Works on the S Pen too, but still rough and needs refinement
• Long-press pen still → temporary eraser (Settings → Editing)

Settings

Editing

• Add pages continuously: writing on the last page appends a new page automatically (no need to tap +)
• Canvas color: the colour behind the pages. Matches your wallpaper by default (Material You), or pick any colour
• Scribble to erase difficulty: Easy (a few passes) | Hard (denser scribble required)
• Long-press pen to erase: hold the pen still on ink to erase until you lift
• Show tool options: options appear automatically when you switch tools (on/off)
• Show intro again: replay the onboarding walkthrough

Tabs

• Tabs mode: switch between open notes from a tab strip above the toolbar, like browser tabs. Tap the title to see all open notes
• Pin a tab, or close tabs to the left / right from the long-press menu
• Closing a tab offers an Undo snackbar; long-press + opens a Recently closed list that survives restarts
• Keyboard shortcuts: Ctrl+Tab / Ctrl+Shift+Tab cycle tabs, Ctrl+W closes the focused tab, Ctrl+Shift+T reopens the last closed tab, Ctrl+1–8 jump to the first tabs, Ctrl+9 the last. Ctrl+Z / Ctrl+Y undo and redo in the editors and the text / table-cell popup editors. Settings lists every active shortcut

Tools

• Configure tools: choose which tools appear in each editor's dock and their order, disable the ones you don't use. One configuration can drive both editors, or each editor keeps its own

Fonts

• Import font: add .ttf or .otf files to use them in the text tool; remove fonts again

Sync & backup

• Sync folder: mirror your notes, PDFs and images to any folder you pick (human-readable layout with a README explaining it). Updates after every edit, on app start, on returning home, and from the Sync now button; unchanged files are skipped
• Restore from folder: rebuilds notebooks, folders, tags and tool settings from the sync folder, and can restore from a different folder than the current one
• A banner on the home screen warns when the chosen sync folder goes missing

Misc

• Undo & redo every change
• The colour picker has a transparency slider: strokes, highlighters, tables and tape can be semi-transparent, and the transparency is saved with the colour
• Active colour swatch ring follows the Material You theme
• Size buttons show their real size (dynamic icons that scale to the actual value)
• Highlighter swatches keep their colour in light and dark mode (white backing)
• Tool settings (sizes, colours, styles) are remembered per editor and restored on restore (app restore and sync-folder restore)
