About Trazu

Trazu is a mobile painting and drawing app with real paint physics. Your brush carries a finite charge of paint that depletes as you stroke, picks up and mixes with the wet color already on the canvas, and catches on real paper grain. Six mediums behave like the real thing: oil drags and blends, watercolor blooms, charcoal and pastel catch the texture. Twenty-plus brush tips, nine paper textures, and a full toolkit: eyedropper, flood fill, selection, transform, crop, canvas resize, and photo import for reference. Built-in study views flip your painting into value, temperature, saturation, and contrast maps so you can see why it works. Everything runs offline: no account, no internet, no ads, and your drawings stay on your device. Export to PNG or JPEG. Free to start with the full paint engine and up to 10 drawings; a one-time Premium purchase unlocks unlimited drawings and the study views. No subscription. Available in eight languages on iOS and Android, for phones and tablets.
