PaintMatchr

PaintMatchr helps homeowners identify and re-buy the exact paint color already on their walls—without guessing, keeping old cans, or making multiple store trips. You take a few photos of the wall in different lighting and place a cheap calibration card (mailed to you or printable) in-frame. The app estimates the closest match across major paint brands and finishes, then generates a shopping list with quantities based on your room dimensions. It also warns when a “perfect match” is unrealistic due to aging, sheen differences, or textured surfaces, and suggests practical alternatives (feathering edges, repainting a whole wall, primer needs). This is not a magic wand: it won’t beat a professional spectrophotometer every time, but it can drastically reduce trial-and-error for touch-ups and small repaints—where most DIY frustration happens.
