Paintingstack

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.

Have a real, open voice conversation in the language you are learning, about anything you want. Mintza is a bilingual AI teacher that talks back like a person, follows your lead, and helps you in your own language when you get stuck. Practice speaking any of fifteen languages, in either direction. 10 free minutes, no subscription required.

Point your phone at anything and see the color structure underneath. Palette with proportions, color harmony, temperature map, and value structure. Built for people who mix paint, grade photos, and design with color.
