Batch Balancer: Lye Calculator

Batch Balancer is a soap calculator and lye calculator for hobbyist soap makers. Work out the lye and water amounts for your oils, scale a recipe up or down to fit your mold, and keep a saved record of every batch you make — ingredients, amounts, and notes — so a good batch can be made again exactly.

Making soap from scratch lives or dies on the math: too much lye and a bar is harsh, too little and it never quite becomes the bar you planned. Batch Balancer does that math with you at the scale, then keeps the record, so the recipe that worked is the recipe you can repeat — not the one you half-remember.

WHAT IT DOES
• Lye and water calculations — enter your oils and get the lye and water amounts for that recipe.
• Recipe scaling — scale a recipe up or down to fit your mold, instead of re-working every amount by hand.
• Saved batch records — keep ingredients, amounts and notes for every batch, so a good batch can be made again exactly.
• A record keeper, not just a calculator — your batch history stays together in one place, batch after batch.

PRIVATE, SIMPLE, ON YOUR DEVICE
All calculations and all of your saved batches stay on your device. The app collects no data and has no accounts. We don't collect your data.

FREE, SUPPORTED BY ITS SHOP
Batch Balancer is free, with no ads in the app. The Shop tab links to soapmaking supplies sold by third parties on eBay; those links are affiliate links, which means the developer may earn a commission on purchases made through them, at no extra cost to you. That shop — not ads — is what supports the app.
