## What is Colorimeter?

Turn your iPhone into a pocket colorimeter. Point the camera at any surface — a flower, a wall, a fabric swatch — and read its color instantly, in every format you need.

POINT. READ. CAPTURE.
• Live color readings straight from the camera viewfinder
• Values in HEX, RGB, HSB, Lab and CMYK, updated in real time
• Freeze the reading with one tap to examine or save it calmly
• Full-screen camera mode with overlay controls
• Tactile feedback on every capture

SAMPLE FROM YOUR PHOTOS
Pick any image from your library and tap a point to read its exact color. Perfect for moodboards, references and pictures you took on site.

YOUR PALETTE, ALWAYS WITH YOU
Every captured color lands in your History: a clean grid of swatches with HEX codes, ready to copy or share. Your collection is stored with iCloud, so it follows you across your devices.

PRO-GRADE CALIBRATION
Ambient light fools cameras. Colorimeter's Accurate mode fixes that:
• Calibrate with any 18% neutral gray reference card
• The app estimates the scene's real illuminant from the gray
• A Bradford chromatic adaptation (in LMS cone space) corrects every reading toward your target illuminant, D65 or D50
• Create and manage a profile for each lighting condition
• Calibrated captures store Lab values you can trust

MADE FOR DESIGNERS, PAINTERS AND MAKERS
• Choose your preferred format for quick copy
• Adjustable sampling patch size for noisy surfaces
• Light, dark or system theme
• Modern, fast, native SwiftUI app

HONEST BY DESIGN
• 100% ad-free — no banners, ever
• No accounts, no tracking, no analytics
• Your colors stay in your private iCloud

A note on accuracy: readings are indicative. A phone's RGB sensor is not a spectrophotometer, and metallic or iridescent finishes are out of reach for any camera. For everything else, calibration gets you remarkably close.
