Hexnut is the fast, no-nonsense hex color picker. It does one job cleanly: get exact color codes and copy them in a tap. No accounts, no ads, no tracking — and it works fully offline. PICK WITH PRECISION Drag the saturation/brightness field and hue rail, fine-tune R, G, B, or just type a hex code. A live preview shows your color instantly. SAMPLE FROM ANY PHOTO Load a photo and drag the loupe to read the exact hex of any pixel. Perfect for matching a color you spotted in a design, a screenshot, or the real world. EVERY FORMAT, ONE TAP HEX, RGB, HSL, HSB, plus ready-to-paste SwiftUI Color and UIKit UIColor code. Tap any row to copy. CHECK CONTRAST See the WCAG contrast ratio against white and black with AA / AAA pass badges — handy for accessible, readable color choices.

Founder quote

“Hexnutis 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
