SparkyDraw – Simple-to-use, all-device drawing web app for children

SparkyDraw is a simple, delightful drawing web app designed for children (and not only!), compatible with any device and screen format (touch, pen/pointer & mouse friendly) and in any orientation. It remembers your artwork and settings across visits, exports high-resolution PNG images locally and adapts easily in small or big screens, in both portrait and landscape modes!

Supports multiple languages (more to be added - auto switch enabled) and is built with pure Vanilla HTML, CSS & JS — zero external frameworks, libraries or build tools.

As a PWA, it can also be installed on any device for quick access.

Zero ads, seamless updates.

P.S. This was purpose built, out of pure necessity, as it got frustrating having a simple app that is kid-friendly to draw on any device.
