civvy.tech is a collection of free, browser-first tools for daily tasks that should be easy but are often frustrating online. Every calculator is built from a verified formula, tested by hand, and kept free of logins, popups, and clutter.
Most utility websites are overloaded with friction: popups, ad walls, and unnecessary sign-up steps. civvy.tech was created to be the opposite. Every tool is designed to open quickly, work clearly, and finish the task without distractions โ and every result is backed by a formula you could check yourself if you wanted to.
Pages should load fast on regular mobile networks and low-power devices, not just high-end desktops.
Inputs are simple, labels are obvious, and results are explained in plain language whenever possible.
Calculations happen in your browser. We do not collect or sell personal calculation data.
Krishna Sapkota
Creator & Developer, civvy.tech
civvy.tech is built and maintained by Krishna Sapkota, a software developer who writes the calculation logic behind every tool by hand and checks it against reference sources โ WHO and NHS guidance for the health tools, published financial formulas for the money tools, and official grading regulations for the VTU student tools โ before anything goes live. Written explanations are drafted with AI assistance and then reviewed and edited for accuracy; nothing is published unedited.
Every tool on civvy.tech goes through the same three checks before it's published or updated.
Each calculation is based on a published, citable formula or standard โ for example WHO BMI bands or NHS hydration guidance โ never guessed or approximated.
Every tool is tested against hand-calculated examples and edge cases before release, so the output matches the underlying formula exactly.
Tools and their explanations are revisited as guidance changes โ such as updated WHO thresholds โ and pages note when they were last checked.
