Soap calculator & lye calculator for cold process and liquid soap
Soap Calculator – SoapCalc opens on the exact search term, with "Safe Lye Calculator" and "Accurate NaOH & water for any soap recipe" set in large type on its first screenshot. TCL Soap Calculator answers the query more completely inside the frames, showing a finished recipe with "Lye (NaOH) (purity: 99.8%) 69.3 g" and a full soap-properties graph, but its captions stay on "soap" and its repeated "THE COSMETICS LAB / SOAP CALCULATOR" header consumes the top third of every image. The match to intent is where the gap opens, not the depth of the product.

App B
Value Proposition
B leadsTCL Soap Calculator's first caption promises "Create perfect soap recipes in seconds", but the word lye appears only inside a small table row.
Soap Calculator – SoapCalc leads with "Safe Lye Calculator" and "Accurate NaOH & water for any soap recipe", matching the query word-for-word.
Clarity
TiedTCL Soap Calculator shows real output: oils with percentages, "Water 138.5 g", lye grams, then property bars with recommended ranges and oil sliders.
Soap Calculator – SoapCalc pairs plain captions "Snap a Recipe Photo" and "Recipe Insights" with Bar/Liquid/Cream tabs and trace and unmould rows.
Emotional Hook
TiedLavender sprigs and the photographed "Lavender breeze" bar add craft warmth, but no soapmaker appears and captions name features, not feelings.
"Know what your recipe will do" names the underlying worry, yet all four frames are device mockups on flat mint and cream backgrounds.
Trust Signals
B leadsThe "trusted by thousands of soapmakers since 2012" claim sits only in the description; on-image proof is the masthead and a tiny copyright line.
The headline word "Safe" plus visible test-batch and "actual results vary" disclaimers read as caution cues; no ratings, awards or user counts shown.
Soap Calculator – SoapCalc draws consistent enthusiasm for being free and the go-to tool for cold process soap making, with one reviewer calling it 'The BEST app for those making cp soap'. The same review set also shows two recurring frictions: recipe saving limits behind a paywall plus uncertainty about offline storage, and an interface described as harder to navigate than the earlier version. TCL Soap Calculator has only a single supplied review, praising ease of use, which is not enough evidence to establish any recurring theme.

MediumTCL Soap Calculator positions on provenance and depth: a free, ad-free tool "created by a soapmaker for soapmakers" since 2012, framed explicitly as the modern replacement for SoapCalc. Soap Calculator – SoapCalc positions on input automation: the same lye math plus "Snap a recipe photo" import and a Blend Advisor that suggests oil-blend changes. The mismatch is credibility-and-control versus speed-and-assistance, so both listings answer "lye calculator" but sell different reasons to switch.
App A
Positioning

Target audience
Cold process soapmakers, beginner through experienced, wanting control
Value promise
Free, ad-free calculator balancing beginner guidance with advanced control
Tone

App B
Positioning
Automated recipe capture calculator
Target audience
Recipe collectors making cold process, liquid, hybrid soap
Value promise
Accurate lye math plus photo import and blend suggestions
Tone
modern, benefit-led, lightly conversational
Gap
TCL Soap Calculator leads with craft credibility and cost ("trusted by thousands of soapmakers since 2012", free and ad-free, manual control via Recipe Tuner), while Soap Calculator – SoapCalc leads with automation (photo-to-recipe import, Blend Advisor suggestions) and treats lye math as table stakes.
Opportunity
Manual control and a decade of use are exactly what experienced soapmakers distrust automation for, so TCL Soap Calculator can claim the accuracy-and-authorship position that an AI-suggestion listing cannot credibly contest.
Risk
TCL Soap Calculator's differentiators are resource claims ("FREE & AD-FREE", more features) rather than capability claims, and the listing discloses a "Save up to 20 recipes and 5 templates" cap directly under the free framing. A searcher comparing the two sees one listing promising a new capability and one promising the absence of ads with a stated storage ceiling, which weakens preference among users choosing a long-term recipe home.
Strategic advantage
The 2012 track record and the SoapCalc-successor framing give TCL Soap Calculator a switching story aimed at soapmakers who already use a legacy calculator and want the same rigour with a cleaner interface, a buying motive rooted in continuity, not novelty.
Missed opportunity
Neither listing addresses lye handling anxiety: both treat NaOH and KOH as arithmetic, and neither names the safety margin, caustic-handling caution, or first-batch reassurance that a beginner searching "lye calculator" is actually nervous about. Safe-by-default is unowned in this pair.

Soap Calculator – SoapCalc
Strong lead
Soap Calculator – SoapCalc holds rank 2 for lye calculator against TCL Soap Calculator at rank 4, and the gap traces to intent match rather than product depth. Soap Calculator – SoapCalc says the search term in its short description and on its first screenshot, while TCL Soap Calculator keeps its strongest evidence one tap deeper.
Why it wins
Soap Calculator – SoapCalc names the query where it is read first, opening on "Safe Lye Calculator" in large type and carrying lye calculator into its short description, so the listing confirms the search in seconds. TCL Soap Calculator shows the more complete answer inside its frames, including a finished "Lye (NaOH) (purity: 99.8%) 69.3 g" recipe and a soap-properties graph, but a repeated brand header takes the top third of every image and the captions stay on the broader term.
Biggest opportunity
TCL Soap Calculator's short description does not yet carry lye calculator, and adding it alongside the 2012 track record converts an existing credibility asset into search-visible proof that Soap Calculator – SoapCalc cannot match.
Next priority
Test a short description that fronts the term and the record together, e.g. "Free lye calculator & soap calculator, trusted by soapmakers since 2012" (69 characters). The second test is whether the first screenshot leads with the recipe output instead of the brand header, since the depth already exists and is currently arriving late.
