Which products we accept

A product's main purpose has to fit one of the topics the blog compares:

  • Math & Computing. Calculators, expression parsers, numeric precision and computer algebra.
  • AI & STEM Tools. AI math solvers and STEM computation, with their limits stated plainly.
  • Financial Modeling. Loan, interest and cash-flow maths for developers and analysts.
  • Developer Utilities. Libraries and utilities for dates, randomness and data transformation.
  • SaaS & Engineering Estimation. Cost, pricing and engineering estimation tools.

We decline general business software even when it contains a calculator — for example invoicing, budgeting, payroll, HR, CRM, project management, website builders or marketing tools. Keeping the articles focused is what makes a placement worth having.

How sponsored placements work

  • Each comparison article has a few reserved slots, shown as “[Sponsored Feature / Available Slot]” while they are open. A sold slot shows your product's verified details under a clearSponsored label, and the article gains a sponsorship disclosure at the top.
  • Sponsored listings sit between the numbered entries, never inside the ranking. Paying for a placement does not change which products we rank, what we say about them or their order.
  • Links in sponsored listings use rel="sponsored nofollow", as search engines require for paid links. We sell disclosed visibility in front of relevant readers — not backlinks, rankings, traffic guarantees or any other SEO outcome.
  • Listing text is short and factual. We check it against your website and may edit it for accuracy and length, and we can decline or remove a listing that turns out to be misleading.

What happens next

Advanced Calculator is a small project, so replies usually take a few days. If your product fits, we reply with the open placements, their terms and the listing details we need. If it doesn't, we'll say why.
