The ToolsACE Team
We are a small group of software engineers and technical writers who build, document, and review every tool on ToolsACE. We are not a faceless content farm — and we are honest about what we are: builders who care about getting the math right and citing where it comes from.
How we earn your trust
We are engineers and writers, not licensed clinicians, financial advisors, or attorneys. So instead of asking you to trust a title, we show our work: we implement each tool against a documented, published standard, test it against known results, and link the authoritative sources we used.
For health, pregnancy, and other sensitive calculators, our results are educational and should not replace advice from a qualified professional. Every such tool carries a clear disclaimer and links to primary sources so you can verify the underlying guidance.
Our working principles
We build the tools ourselves
Every calculator, converter, and generator is implemented in-house in TypeScript and runs entirely in your browser. There are no third-party calculators embedded behind the scenes.
We verify against the published formula
Each tool is checked against the standard, equation, or specification it implements — for example, the WHO BMI classification or the Mifflin–St Jeor equation — and tested with known inputs and expected outputs.
We cite primary sources
For health, finance, and other accuracy-sensitive tools, we link the authoritative references we relied on (WHO, CDC, NIH, ACOG, AHA and similar) directly on the tool page so you can check the source yourself.
We review and date our content
Tool pages show when they were last reviewed. When a formula, guideline, or recommendation changes at the source, we update the affected tools and refresh the review date.
We store no personal data
Calculations happen on your device. We do not require an account, and we do not collect or retain the values you enter.
We do not fake trust signals
We do not publish invented star ratings or review counts. Where we have not built a genuine review system, you will not see one. Our credibility comes from transparent methodology, not decoration.
Spotted something we got wrong?
We read every message and fix verified errors quickly. Accuracy corrections from readers make the tools better for everyone.
