NotePad is a clean, native iPad note-taking app built for Apple Pencil. It feels like a paper notebook with the power of digital ink. - Handwriting with pressure and tilt, low latency, and palm rejection - the Pencil draws while a finger scrolls and two fingers zoom. - GoodNotes-style tool bar: pen, highlighter, erasers, color dropdown and widths. - White paper or blackboard templates, applied across the whole notebook. - Shapes and flowcharts (process, decision, start/end, connectors) with editable vector overlays; connectors re-route when you move a node. - Type directly into sticky notes and flowchart nodes (multi-line, with background colors). - Lasso to move, delete or copy multiple strokes; recolor and edit shapes. - Import PDFs and annotate them; export pages or whole notebooks to PDF/PNG/JPG. - Organize with nested notebooks and tags, and search inside your handwriting. - Record voice memos per notebook. - Everything syncs across your devices with iCloud.
