Store description excerpt
Anyone can save what you wrote. Nib Echo saves how you wrote it. REPLAY THE ENTIRE PROCESS Press play and watch the page rebuild itself — every stroke, every pause, every correction, in the order it actually happened. Not a static image of the answer, but the thinking that led to it. Speed it up to 2x, slow it to 0.5x, or drag the waveform straight to the moment you care about. Perfect for lectures you want to revisit, tutoring you want to send home, design reviews you want to justify, and problems you want to work through again tomorrow. STROKES, NOT PIXELS Nib Echo doesn't record your screen. It records the motion of your pen as data — which is why a full session stays a tiny file instead of a giant video. Keep hundreds of them on your phone. Send one over chat without waiting for an upload bar. Your whole notebook weighs less than a handful of photos. AN INFINITE CANVAS Stop planning around page edges. Pan in any direction, zoom out to see the whole idea, zoom in to work on one corner of it. Mind maps, system diagrams, lesson plans and brainstorms get as much room as they need — and the replay follows your camera, so viewers see exactly what you were looking at. CAMERA, VOICE AND INK ON ONE TIMELINE Record your face and your voice while you write. All three tracks stay locked together, so the explanation always lands on the right stroke. Export it as a finished MP4 and you have a full lesson — no editing software, no second take. PDF ANNOTATION Drop in a PDF and mark it up page by page. Insert blank pages where you need more room, reorder them, delete the ones you don't want, then export the whole marked-up document back to PDF. Contracts, papers, sheet music, homework — all in the same app as the rest of your notes. EVERYTHING ELSE YOU'D EXPECT Seven pens from fountain to marker to highlighter. Shapes, text and images you can scale, rotate, mirror and crop. Stroke, area and full-page erasers. Thirty page templates from plain grid to Cornell, staff, storyboard and isometric. Folders, search and sorting to keep it all findable. Export to MP4, PDF, PNG or audio. Works fully offline. No account, no setup — open it and write. NIB ECHO PRO Unlock the infinite canvas, camera recording, the full template library and extended recording length. Remove ads and export without a watermark. Monthly, half-yearly and yearly plans, cancellable any time in Google Play. Available in English, 简体中文, 繁體中文, 日本語, 한국어, Deutsch, Español, Français, Italiano and Português (Brasil).
