Trazu is a mobile painting app where paint behaves like the real thing: it loads, depletes, mixes when wet, and drags across the grain of the paper. Six mediums (oil, watercolor, charcoal, ink, pastel, plus a basic brush), nine real paper textures, and four study views (value, temperature, saturation, contrast) built into your canvas. 20+ brushes, flood fill, reference import, export. No account, no ads, works offline. Real paint, no mess.

Hi everyone, we're Paintingstack, the studio behind Trazu. We built Trazu because drawing apps come in two extremes: professional tools like Procreate that bury you in features and a learning curve, or free apps that drown you in ads and lock basic tools behind paywalls. We wanted the middle, an app that respects your time and just lets you draw. The part we're proudest of is the paint itself. Most apps lay down flat strokes. In Trazu the brush carries a finite load of paint that depletes as you stroke, picks up and mixes with the colors already on the canvas when it's wet, and catches on the tooth of the paper you picked, so charcoal breaks up over the grain and oil drags and blends like the real thing. Everything runs on your device. No account, no internet, no ads. Free to start with generous limits, and a single one-time Premium unlock (no subscription, $9.99) for unlimited drawings and the four study views. It's on iOS and Android, in eight languages. We'd love your feedback, especially on how the brushes feel under your finger or pencil.

how does the pigment mixing actually handle when you're layering wet oil over a partially dried section — does it stay believable or start looking muddy?
