A painting and drawing app. Free to start. Trazu Premium is a single one-time purchase, yours for life, no subscription. The brush carries a charge of paint that depletes as you drag, picks up wet color already on the canvas, and responds to pressure and speed. Nine mediums, each with its own behavior. Oil drags and blends. Watercolor goes translucent and blooms at the edges. Charcoal, chalk, and pastel catch the grain. Ink stays crisp. Airbrush lays soft gradients, blending stumps move paint without adding any, and a basic medium covers quick sketching. Paint in layers. Keep the sketch, the color and the details apart, and hide, rename, fade or merge any of them. Select part of a layer by rectangle, freehand or ellipse, then move, scale or turn it. Composition guides sit over the canvas while you paint and never reach your export: the rule of thirds, diagonals and a grid, and the classical constructions of the masters, from the golden section and golden spiral to dynamic symmetry and the harmonic armature. Over twenty brush tips, twelve paper textures, six canvas shapes, a full HSB color picker with hex input and recent colors. Eyedropper, paint bucket flood fill, symmetry, flip, and undo. Import a photo and paint over it. Four study views (Value, Temperature, Saturation, Contrast) let you flip the canvas and read your work while you paint. Everything stays on your device. No account, no sign-up, no ads, no cross-app tracking. Works fully offline. Free includes over twenty brushes, nine papers, three layers, the everyday composition guides, PNG and JPEG export, and ten saved drawings. Trazu Premium removes the drawing limit and unlocks up to twenty layers, the classical composition guides, the four study views, transparent PNG export, six master brushes (silverpoint, conté, scumble, blending stump, tortillon, and airbrush), and three master papers (black, laid Ingres, terracotta).
