KeptBook is a precise paint-mixing calculator and personal record book for anyone who colors, paints or decorates. Enter the shades you want to blend, give each a share, and KeptBook tells you exactly how many milliliters of every shade you need. Don't know the total volume? Switch on the area estimator, enter the width and height of the wall, choose the number of coats and the surface type (standard wall, bare wood or metal), and the amount is worked out for you. A live stacked chart shows each shade's proportion at a glance. When you are happy with a blend, save it under a name such as "Living Room Wall" and find it again in your archive any time. FEATURES - Per-shade milliliter amounts from simple ratios - Area estimator with coats and surface absorbency - Visual stacked blend chart - Saved archive of past blends with full details - Delete single records or clear all data - Clean, minimal black-and-white design - Works fully offline; everything is stored on your device KeptBook keeps every formula, so the perfect color is never lost.
