Stop wasting resin/epoxy. Stop second-guessing your ratios. Resin Calculator Master is the complete calculation toolkit for resin artists, epoxy crafters, jewelry makers, and anyone working with two-part mixed materials. Whether you're mixing a small batch, filling a custom mold, or managing a multi-step pour — this app handles every number instantly, right on your iPhone. NO MORE WASTED RESIN The Quick Mix Calculator takes your resin's ratio in any format — 1:1, 2:1, 100:30 — plus the total amount you want to make, and tells you exactly how much Part A and Part B to measure out. Choose your unit: grams, ounces, milliliters, or fluid ounces. Switch between weight and volume input mid-session without losing your numbers. No mental math. No scraping residue from an over-poured cup. VOLUME ESTIMATOR FOR ANY MOLD The Project Estimator calculates exactly how much resin you need to fill a mold. Choose your mold shape — cylinder, rectangular block, sphere, half-sphere, cone, torus ring, or prism — then enter the dimensions. The app calculates the fill volume, applies a waste factor buffer for material left in the mixing cup, and converts that into the exact weight of resin to prepare based on your density setting. Works for jewelry molds, coaster molds, river table pours, and large casting projects. WEIGHT / VOLUME CONVERTER Most resin brands state mix ratios by weight. Most measuring cups show volume. The Weight/Volume Converter bridges this gap instantly. Select from built-in density presets for common resin and epoxy types, or enter a custom specific gravity from your brand's data sheet. Every result includes a confidence level indicator so you know how accurate the conversion is given your input precision. STEP-BY-STEP MIXING TIMER The Mixing Assistant guides you through each stage of a resin session with a dedicated countdown timer for every step: - Measure and prepare both components - Mix until fully combined - Degas in a pressure pot or vacuum chamber - Pour into your mold carefully - Cure — with a 1-minute alarm before your step ends The timer runs in the background while your screen is locked and fires a local notification when your step is almost up. Never over-mix again. Never lose track of your pot life window mid-pour. SAVED BRAND AND MOLD PROFILES If you work with the same resin brands and molds repeatedly, Profiles removes all the repetitive data entry. Create a Brand Profile with your resin name, mix ratio, and density. Create a Mold Profile with shape selection and dimensions. Tap any saved profile to instantly load those values into the Quick Mix Calculator, Project Estimator, or Converter — every session starts ready to go. MATERIALS CHECKLIST Before you open a bottle, the built-in prep checklist walks you through everything: safety equipment, workspace setup, mold release, component temperature, and material readiness. Tap each item to check it off. Pouring prepared prevents expensive and frustrating wasted batches. PRO TIPS AND SAFETY WARNINGS Contextual tips appear throughout the app as you work — covering how ambient temperature affects cure time, when to use a heat gun for bubbles, what pot life means for your pour window, and how to avoid fish-eyes and cloudiness. Safety warnings appear automatically when your inputs flag a potential issue worth noting. PREMIUM — ONE-TIME PURCHASE 1.
