Improving the Paint Ninja Drawing App

06 April 2026

I’ve been quietly working on improving the Brush Ninja drawing app over the past few weeks. Nothing flashy on the surface, but lots of small upgrades that make it nicer to use.

There are a few new features, along with some general code tidy up to fix bugs and improve performance.

The biggest change is the addition of layers. You can now draw on separate layers, hide them, and build up your artwork in stages. It opens the door to more complex drawings without making things harder to manage, and it sets things up nicely for future features.

There’s also a brand new smudge tool. This lets you push colours around the canvas, a bit like dragging wet paint with your finger. It’s surprisingly fun. You can soften edges, blend colours, or just make a mess and see what happens.

I’ve also added a pipette tool. This one’s simple but useful. You can grab colours directly from your drawing instead of guessing or tweaking sliders. It makes it much easier to stay consistent, especially when you’re working with shading or gradients.

The paint brush has had some attention too. It feels smoother and more responsive, especially when drawing longer lines. There’s automatic smoothing to reduce jitter, better spacing, and it behaves more like you’d expect.

Overall, this is a solid step forward. The app still aims to stay simple and approachable, but it now has a bit more depth if you want it. Paint Ninja is still in beta, so I’m keen to keep improving it based on feedback and how people actually use it.

As with everything on Brush Ninja, it’s free to use, and there’s no account or sign up required. Just head over to the drawing app and give it a try.
