Your notes remember how they were written.
Nib Echo records every stroke as you write, then plays it back in perfect time with your voice — and, if you like, a floating camera bubble of you. Write on a page, an endless canvas, or straight onto a PDF. Scrub the timeline — watch it draw itself.
The loop
Write once. Live it again.
Nib Echo turns a note into a recording, and a recording into something you can rewind, share, and keep.
Write
Seven pens — fountain, brush, pencil, ballpoint, marker, dashed, highlighter — on any of 30 papers.
Record
Strokes, your voice, and an optional camera bubble — captured together, timed to the millisecond.
Replay
Every stroke redraws in order, in sync with the audio. Seek, pause, 2×, volume.
Export
An image, a flattened PDF, or the whole replay as an MP4 — ink and sound.
Three ways to start
A page, a plane, or someone else's document.
Not every thought fits on a page. Pick the surface that matches the thinking — all three record, replay, and export the same way.
The page
A bounded sheet with layers, portrait or landscape. Add pages, reorder, delete — the classic notebook, with a memory.
The infinite canvas
No edges. Pan and zoom forever, spread a whole argument out flat, then jump back to where you began. The replay pans with you.
A PDF
Import a document and it splits into pages you can write on directly. Add or delete pages, then export it back out — annotations flattened in.
Built for thinking
A quiet canvas with a long memory.
Everything you'd expect from a serious note app — and one thing no other has: the whole session, kept in time.
Echo Playback
Replay, not just review. Every stroke returns in the exact order you made it, synced to the audio you recorded while writing. Scrub anywhere, pause on a moment, race through at 2×, or ride the volume down without leaving the page. On an infinite canvas the view travels too — you get the pans and zooms back, not just the ink.
Layers
Stack and toggle like a drawing app. Add, hide, and reorder layers to keep a busy page under control.
A nib for every hand
Seven pens, each with its own weight and character — a pencil with real graphite grain, a brush that widens with your speed and fades at both ends — plus shapes and a full color wheel.
You, in the corner
Turn on the camera and a floating bubble records you while you write — drag it anywhere, switch lenses mid-take. It replays and exports exactly where you left it.
NewErase your way
Stroke, region, or whole page — with an adjustable eraser width you can see before you touch the ink.
Image & text
Drop in a photo or a caption. One transform bar scales, rotates, and moves both.
Thirty papers
Cornell, staff and tab, storyboard, isometric, four-line, Séyès, graph, quadrant — each note remembers the one it was written on.
Ten languages
English, 简体中文, 繁體中文, 日本語, 한국어, Deutsch, Français, Español, Português, Italiano.
Private by design
Your notes stay yours. Each .wv file is encrypted on device — strokes, audio, video, and all. Nothing is uploaded, because there is no account to upload it to.
AES-256Pro, when you outgrow the page
The app is free, and stays useful free. Pro removes ads and export watermarks, opens the infinite canvas and all 30 papers, turns on camera recording, and stretches a session from 10 minutes to 60.
Take it anywhere
Export the moment, not just the page.
Pick the pages you want as crisp images, hand an annotated PDF back as a PDF, or render the entire replay to an MP4 — ink drawn frame by frame, camera bubble composited in, your audio underneath. A hardware-accelerated pipeline keeps even long recordings quick. Straight to your gallery.
The craft
“The canvas is the protagonist. Everything else stays quiet until you need it.”
A warm, precise design language — low-contrast tooling, no ripple noise, paper that feels like paper. Built on a custom system tuned for handwriting.
Start a note that never forgets.
Free on Android, with Pro for when a page stops being enough. Your handwriting, kept in time.
