Resin Pour Planner

Plan transparent resin, epoxy and Jesmonite pours without hiding the maths. Resin Pour Planner keeps ratio by weight and ratio by volume as separate modes, names every unit, and shows the calculation basis beside the answer. Choose a rectangle, round, oval, ring, sphere or half sphere mould, or enter a custom measured volume. Set the number of moulds and an extra mix percentage. The app explains that extra mix means a percentage of the whole cavity volume, before density and the component split are applied. Copy the ratio from your product label and enter clear names for both parts. In weight mode, the app divides the required wet weight by the total ratio parts. In volume mode, it divides the planned volume by the total ratio parts. Density is used only when a weight result genuinely needs it. The two modes are never silently converted or treated as interchangeable. Every valid plan shows: - one-mould volume and whole-batch volume - the exact extra mix calculation - volume-to-weight conversion when density applies - Part A and Part B amounts with units - each component's percentage of the calculated total - displayed rounding reconciled back to the displayed total - package cost, batch cost and cost per mould Save moulds for repeat work. Save mixtures with ratio, density and package prices. Record completed batches in history, then reuse the same checked setup instead of doing the hand maths again. A portable JSON backup covers moulds, mixtures, prices, settings and history. No account is required. Everything people expect from resin mix, ratio, epoxy and hardener calculators is kept in one transparent workflow. Built-in examples are starting references only. Always copy the current manufacturer's ratio and instructions from your own product label or technical data sheet. Follow the maker's safety guidance, personal protective equipment, mixing time, working time, temperature and maximum pour depth. Your workshop records stay on your device. The free installed app contains one bottom banner and occasional interstitial ads after selected saved batches. A permanent Remove Ads purchase is available through Google Play. The browser version remains ad free.
