About univtool
Free, open‑style tools for students, engineers, and everyday problem‑solvers.
Who we are
univtool was started by a small team of engineers and educators who believe that high‑quality technical tools should be free and accessible to everyone. What began as a collection of RF calculators for our own students has grown into a suite of tools spanning electronics, finance, mathematics, and more.
What we offer
We currently provide calculators and interactive tools in five main areas:
🔬 Live Student Projects
Real‑world engineering projects with code, schematics, and demos.
📡 RF Engineering
Transmission line calculators, Smith charts, antenna design helpers.
🧲 EM Calculators
Electromagnetic field solvers, skin depth, waveguide tools.
💰 Financial Tools
FD, SIP, EMI, SWP, pension planners, and live market dashboard.
🧮 Everyday Calculators
Math, conversion, date, health – simple utilities for daily use.
Why we do it
We’ve all been frustrated by clunky, ad‑ridden tools that hide basic functionality behind paywalls. univtool is our answer: a clean, fast, and genuinely helpful resource. We keep it free thanks to our community and through carefully chosen affiliate links – when you buy something through one of our recommendations, we may earn a small commission at no extra cost to you.
👥 The team
univtool is maintained by a handful of engineers who love building useful things. We’re always happy to hear your feedback or suggestions.
