Frequently Asked Questions

SolversPro is a comprehensive suite of free, lightning-fast online calculators and utilities for professionals, students, and everyday use. We cover everything from finance and health metrics to complex engineering calculations, developer tools, and an AI-powered universal solver.

Yes! All of our standard calculators, converters, and developer utilities are completely free with no hidden costs. We believe essential calculation tools should be accessible to everyone without paywalls or mandatory sign-ups.

No account or registration is required. You can start using any calculator on SolversPro instantly — just visit the page and begin. The optional Dashboard feature uses your browser's local storage, so it works without an account too.

Absolutely. The vast majority of our tools run entirely client-side in your browser — your inputs never leave your device. If you use the Dashboard to save results, that data is stored locally using your browser's localStorage. We do not collect, transmit, or store your personal calculation data on our servers.

We use Google Analytics to understand aggregate site traffic (e.g., which pages are most popular). We do not use tracking cookies for advertising or sell any user data. You can read more in our Privacy Policy.

We offer 90+ tools across ten major categories: Finance (tip calculator, live currency converter, compound interest, simple interest, ROI, mortgage, cash-on-cash return), Health (TDEE, BMI Calculator with visual gauge, and Child & Teen BMI Calculator with CDC growth percentiles), Math (age calculator, percentage calculator, scientific calculator, quadratic solver, statistics, geometry, matrix, unit converter, random number generator), Trades & Engineering (concrete slab, wire size, board feet, paint calculator, solar panel), Developer Tools (JSON/XML tools, format converters, data-to-class generators, diff tools, code beautifiers, string escapers, hash generator, regex tester, Base64 converter, color converter, JWT decoder, number base converter, timestamp converter, code minifier, slug generator, UUID generator, markdown to HTML), Security (password generator), Network (Internet speed test, network jitter test, bufferbloat test, Internet Radar, IP subnet calculator, My IP checker, IP address lookup), Text (word counter, case converter, lorem ipsum, Morse code, URL encoder, number to words), PDF Tools (merge, split, compose, images to PDF, PDF to images/text/HTML, protect, remove password, flatten, preflight), and QR Code Generator.

Our calculators use industry-standard formulas and are built for professional-grade accuracy. All computations run in real-time using JavaScript's IEEE 754 double-precision floating-point arithmetic, which provides up to 15–17 significant digits of precision.

Yes. SolversPro is fully responsive and works on any modern device — desktop, tablet, or smartphone. You can even install it as a Progressive Web App (PWA) on your home screen for instant access without downloading anything from an app store.

Most of our standard calculators run entirely in your browser and will continue to work with limited or no internet connectivity once the page has loaded. The AI Solver feature requires an active internet connection to process your queries.

The Universal AI Solver is our Gemini-powered assistant that can answer complex math, engineering, physics, and logic questions with detailed step-by-step explanations. Simply type your problem in natural language and get an instant breakdown of the solution.

Yes, the AI Solver is currently free to use. Because it relies on a cloud-based AI model, there may be usage limits during periods of high demand to ensure quality of service for all users.

The Dashboard is your personal command center. It lets you save calculation results from any tool, set global preferences (like default currency and measurement system), and export or import your saved data as a JSON file for backup or portability — all stored locally in your browser.

Yes! The Dashboard includes a full Data Management section. You can export all of your saved results and preferences as a single JSON file, and import them back on any device or browser. This makes it easy to back up your data or move between devices.

SolversPro works on all modern browsers including Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, and Brave. We recommend keeping your browser updated to the latest version for the best experience.
