Precision Tools for Every Calculation
Prufly is a dedicated platform of free, browser-based calculators built to eliminate guesswork, save time, and deliver accurate results — for students, educators, and professionals alike.
Prufly is a professional-grade, fully free calculation platform established in 2026. Designed with clarity and precision in mind, Prufly empowers students, educators, and professionals to perform complex calculations instantly — with zero cost, zero registration, and zero compromise on accuracy.
Who We Are
Prufly was founded on a straightforward observation: reliable calculation tools should not be locked behind paywalls, complex software, or steep learning curves. Our team of educators and developers set out to build a platform that treats accuracy and accessibility as equally non-negotiable priorities.
Since our launch in 2026, Prufly has grown into a trusted resource for over 50,000 users worldwide — from high school students planning their study schedules to professionals verifying financial figures. Every tool on our platform is engineered to be fast, dependable, and straightforward to use.
Prufly tools are built around four core principles:
- Completely Free — No subscriptions, no trial periods, no hidden charges
- Instant & Browser-Based — No software installation or account creation required
- Privacy by Design — All calculations are processed locally on your device; no data is transmitted or stored
- Universal Accessibility — Fully optimised for desktop, tablet, and mobile devices
What We Offer
Prufly hosts a growing library of over 20 specialised calculators and conversion tools, carefully organised across three core categories to serve the broadest range of everyday needs:
- Academic Performance Tools — GPA calculators, grade predictors, attendance trackers, and study planners designed to help students monitor progress and plan effectively
- Mathematics & Scientific Tools — From quadratic solvers and graphing calculators to logarithms, factorisation, and root calculations with step-by-step working
- General-Purpose Utilities — Percentage calculators, fraction tools, date and time calculators, word counters, and number-to-words converters for everyday professional use
