Store description excerpt
DuoBoard is an iPad PDF whiteboard built for live teaching: prepare answers privately, show students a clean screen, and reveal each answer exactly when you're ready. Connect a TV or projector with AirPlay or a cable. Students see the lesson PDF and only the writing you choose to show, while hidden answers, notes, covers, and tools remain on your iPad. PREPARE ANSWERS IN PRIVATE Write answers before class in the Hidden layer. They stay off the student screen until you rub over an area to reveal it—one answer at a time, right on cue. COVER PRINTED ANSWERS Place covers over answers already printed on worksheets, textbooks, or answer keys. Reveal them one by one as you teach. KEEP THE LESSON MOVING • Scratch Pad with plain, lined, and grid backgrounds • Freeze or black out the student screen • Laser pointer • Reusable sticky notes for grammar points, examples, and reminders • Pen, highlighter, text, eraser, and solid, dashed, or wavy lines PRIVATE BY DESIGN No account. No sign-in. No servers. DuoBoard collects no data and never uploads your files. Everything stays on your iPad. Requires an iPad and Apple Pencil. Two-screen mode requires an external display connected via AirPlay or a cable.
