As answered by people managing TrackMyDueDate and ShellNewHandler.
TrackMyDueDate's answer
Unlike bloated pregnancy apps that require sign-ups or bombard you with ads, Duedatecalc.online is laser-focused on one thing: giving you an instant, accurate due date. There’s no registration, no tracking, and no clutter. The tool is built to work flawlessly on any screen, delivering results using standard obstetric dating in seconds. Its simplicity and privacy-first approach set it apart from feature-heavy competitors that often overwhelm the user.
TrackMyDueDate's answer
They should choose it for speed, clarity, and trust. Many calculators hide results behind email gates, push in-app purchases, or display confusing medical jargon. Duedatecalc.online gives an immediate, easy-to-read breakdown of the due date, gestational age, trimester, and current week—with zero friction. It uses industry-standard Naegele’s Rule, the same logic trusted by healthcare professionals, and it respects user privacy by never storing personal data. If you want a straightforward, reliable answer without the fuss, this is the tool.
TrackMyDueDate's answer
The primary audience is expectant parents (especially first-time mothers and fathers) who want a quick, trustworthy estimate of their baby’s due date. A secondary but equally important audience includes healthcare workers—midwives, doulas, nurses, and OB-GYN students—who need a fast, mobile reference tool during consultations or classes without logging into a larger system.
TrackMyDueDate's answer
Duedatecalc.online was born from the frustration of watching friends and family struggle to find a clean, simple pregnancy calculator online. Every search led to ad-heavy sites, mandatory newsletter sign-ups, or apps asking for unnecessary permissions. The creator—someone passionate about practical, accessible digital health tools—decided to build the most straightforward EDD calculator possible. The goal was never to build a massive platform, but to give any person, anywhere, a reliable answer in seconds, for free, with complete privacy.
TrackMyDueDate's answer
The calculator is built as a lightweight, static web application to ensure maximum speed and reliability. The front-end is pure HTML5, CSS3, and vanilla JavaScript for the date calculation logic, making it fast and without heavy dependencies. The responsive design is achieved with CSS Flexbox/Grid, and the site is served via a global CDN to provide instant loading on any device, from smartphones to desktops.
TrackMyDueDate's answer
Because the tool is free and requires no account, usage is broad and viral rather than contract-based. The biggest “customers” are actually the large pregnancy resource blogs, community health organizations, and antenatal educators who regularly link to or recommend Duedatecalc.online in their materials. It has been embedded in midwifery course resources and shared across international pregnancy forums, making it a trusted go-to for thousands of everyday users worldwide rather than any single enterprise client.
