Chrovis is the fastest way to explore color theory on iPhone. Pick any color, instantly see every classic harmony scheme — complementary, analogous, triadic, split-complementary, tetradic — as clean, copyable swatches. No account. No network. No friction. Pick a color by typing a HEX value, dragging HSL sliders, or opening the system color wheel. Tap any swatch to copy HEX, RGB, or HSL in one tap. The Format Converter lets you type any format and see all three live. Designed for designers, developers, and artists who need a quick, reliable color reference that works everywhere — even offline. — WHAT MAKES CHROVIS DIFFERENT — • Harmony Explorer — See complementary, analogous, triadic, split-complementary, and tetradic schemes instantly for any color. • Format Converter — Type HEX, RGB, or HSL and watch all three update live. • Recent Colors strip — Quickly recall colors you've picked before. • Fully offline — No account or network needed, ever. — PRICING — Chrovis is free to use. A separate Pro upgrade unlocks saving and naming palettes, exporting as an image or CSS/Swift code, a WCAG contrast checker with AA/AAA pass/fail, and unlimited color history. — FEEDBACK — Made by a small indie team.

Founder quote

“Chrovis is built around one principle: your data stays on your device. We don't want it, we don't store it, and we don't need it to make the app work. Everything that can run locally, does.”
— Peter Zhang, solo developer, Obelisk Club
