Trazu - Paint, Sketch, Draw

A drawing and painting app for your phone. 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. Six mediums, each with its own behavior. Oil drags and blends. Watercolor goes translucent and blooms at the edges. Charcoal and pastel catch the grain. Ink stays crisp. Plus a basic medium for quick sketching. Over twenty brush tips, nine 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 every medium, every brush, every paper, PNG and JPEG export, and ten saved drawings. Trazu Premium removes the drawing limit and unlocks the study views.
