Trazu - Paint, Sketch, Draw

A painting and drawing app for iPhone, iPad, and Mac. 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. Over twenty brush tips, twelve paper textures, a full HSB color picker with hex input and recent colors. Eyedropper, paint bucket flood fill, selection, transform to rotate and flip, crop, 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, PNG and JPEG export, and ten saved drawings. Trazu Premium removes the drawing limit and unlocks 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).
