Soap Ledger vs SoapMetrics
SoapMetrics and Soap Ledger overlap closely: both have a NaOH, KOH and dual-lye calculator and a $5.99-a-month plan with batch tracking, inventory and costs. SoapMetrics' calculator needs a free account, and saving recipes is part of its paid plan; Soap Ledger's website calculator needs no account and the Free plan saves 10 recipes. SoapMetrics stores dual-lye recipes and has a built-in assistant, which Soap Ledger doesn't.

Where SoapMetrics is better
- Dual-lye recipes are stored in the app. Soap Ledger's website calculator does dual lye, but an app recipe holds one lye.
- A built-in assistant ("Ask SoapMetrics") on the paid plan.
- One simple paid plan at $5.99 a month, if that's all you want to think about.
Where Soap Ledger is different
- Calculate on the website with no account, and save up to 10 recipes free; saving isn't a paid feature.
- A yearly price ($49 for Maker) and a Shop plan for sellers, with sales import, profit reports and recall tracing.
- Every SAP value has a cited source shown under the result.
Which to choose
Choose SoapMetrics if you make dual-lye soaps often and want them saved as such, or want its assistant.
Choose Soap Ledger if you want to calculate without an account, save recipes for free, or need seller tools later.
What we couldn't confirm
- We couldn't find a yearly price or a trial for SoapMetrics Premium.
Try Soap Ledger. The lye calculator is free with no account; the app's Free plan needs only an email.
