The offline resin planning app that answers every question before you mix. Calculate exact resin volumes, split Part A and Part B in both weight and volume, dial in your pigment load, plan multi-pour deep pours, and save projects with cure notes — no account, no internet.
Nine pour shapes — Rectangle Coat, Round Coat, River Channel, Block Mould, Cylinder, Sphere, Dome/Cabochon, Tapered Mould, and Custom Volume — each with the exact geometry formula. Enter your dimensions and Resinly gives the total resin you need, including your chosen waste margin. River tables include a multi-point width-averaging helper for uneven live edges.
Tell Resinly whether your product mixes by volume or by weight, and it shows the exact amount of Part A and Part B in both units simultaneously. Eliminates the most expensive resin mistake — measuring by the wrong basis. Works for coating epoxy, deep-pour epoxy, casting resin, UV resin, polyester, or any custom ratio you enter.
Once you know your batch mass, choose your colorant type — mica powder, pigment paste, alcohol ink, or oxide pigment — and pick an intensity level (translucent tint, standard colour, or full opaque). Resinly shows the exact grams to add and warns you before you hit the 4% cure-risk ceiling. A multi-colour split tool divides one batch into up to 8 equally sized tinted portions with colorant amounts per portion.
Save any pour as a project, then swipe right to add freeform cure notes — room temperature, humidity, resin brand, cure outcome, anything you want to remember. Notes appear under the project name as a one-line preview so you can see at a glance what worked and what to adjust next time.
Feed in your total volume, pour depth, max comfortable batch size, pot life, and room temperature. The planner splits the job into the right number of batches, shows Part A and Part B mass for each pour, calculates a heat-risk score from batch size, depth, and temperature, and gives a bench-ready checklist. New in 1.2: a temperature working-window gauge using the Rule of 10 — reaction rate roughly doubles per +10 °C rise above 21 °C baseline.
Standalone mixer for any amount you already know — enter total volume, total mass, or the Part A you measured, and get the matching Part B in both cups and grams. Useful when you're scaling a recipe up or down mid-project or double-checking an existing batch.
