What is mobile-ink?

Mobile-ink is a production-grade React Native library delivering native Skia/Metal-powered drawing for iOS apps, handling Apple Pencil input, variable-width strokes, eraser tools, shape recognition, selection, zoom, and infinite continuous notebooks. Extracted from the MathNotes app, it solves the lack of robust open-source ink engines by providing low-latency rendering, JSON serialization, and momentum scrolling without JS thread stalls—ideal for mobile ink stores or notes apps needing pro canvas primitives in C++ under React Native.

Why is it gaining traction?

Unlike basic SVG canvases or JS-heavy drawers that lag on Pencil input or long docs, mobile-ink offers battle-tested performance from a live App Store app, with tools like pen, highlighter, crayon, and pixel eraser that feel native. Devs dig the fixed engine pool for seamless page transitions and batch export to PNG, cutting rebuilds in production-grade React apps. Early adopters praise its docs, example Expo app, and CI stability despite low stars.

Who should use this?

React Native devs building notes, whiteboard, or diagramming apps—like mobile ink crew sketching STEM math or mobile ink PEI designers—wanting Pencil-ready surfaces without native iOS reinventing. Perfect for production-grade React projects needing zoomable infinite canvases, serialization for saves, and selection editing, but skip if you're Android-first or Expo Go-bound (needs dev client).

Verdict

Grab it for iOS notes prototypes—solid API, example app, and real-world use make it a credible start despite 1.0% score from 10 stars and iOS-only maturity. Polish docs and add Android to hit escape velocity; young but thoughtfully engineered.
