Lyewise helps every soap maker craft the perfect bar for their exact needs. From guiding you toward the right oils for the qualities you're after — hardness, lather, conditioning, longevity — to calculating the precise lye and liquid amounts your recipe requires, it turns the technical side of cold-process soap making into something clear, safe, and creative. Whether you're pouring your very first batch or refining a product line, Lyewise helps you understand every bar and make it better.
Lyewise is an all-in-one cold-process soap studio: a precise lye (sodium hydroxide) calculator, a fatty-acid and bar-quality analyzer, additive and fragrance calculators, a searchable oils encyclopedia, a guided gel-phase timer, and a built-in troubleshooting assistant — all in one place, on any device, with your recipes synced to your account.
Lyewise runs in any browser, but you can also add it to your home screen so it opens full-screen with its own icon — no app store needed.
iPhone & iPad (Safari): Open lyewise.com in Safari, tap the Share button (the square with an up-arrow), scroll down and tap Add to Home Screen, then tap Add. On iPhone this works only in Safari, not Chrome.
Android (Chrome): Open lyewise.com in Chrome, tap the ⋮ menu (top-right), tap Add to Home screen (or Install app), then confirm Install. Chrome may also show an Install banner you can tap.
