CalcSphere's answer:
Zakat Calculator with Pakistani Fatwa โ The only free Zakat calculator following the silver nisab ruling of Mufti Taqi Usmani (Fiqhi Muqalat Vol 1, Page 31) and Darul Uloom Karachi. Silver nisab is pre-selected by default for mixed assets.

Perfect PageSpeed scores โ 100/100 Performance, 100/100 SEO, 100/100 Best Practices on Google PageSpeed Insights
CalcSphere's answer:
No clutter โ Unlike calculator.net and rapidtables.com, CalcSphere puts the calculator first with no pop-ups, no distracting ads blocking the tool, and instant results
Mobile-first design โ Built with Next.js 14 and Tailwind CSS, CalcSphere loads in under 1 second on mobile (LCP 1.3s) โ faster than most competitor sites
Dark and light mode โ Clean modern UI with full dark mode support unlike most legacy calculator sites
Dropdown inputs โ No need to type unit abbreviations manually โ all unit converters use dropdown selection
Rich explanations โ Every calculator includes a "What is" section, step-by-step how-to guide, pro tips, and real-world use cases โ not just a bare calculator
Pakistan-specific tools โ Zakat calculator, construction cost per marla, PKR salary calculator and EMI calculator built for Pakistani users โ not available on international competitors
CalcSphere's answer:
CalcSphere serves four main audiences:
Pakistani users โ Professionals, students and homeowners calculating EMI, Zakat, construction costs, salaries and inflation in PKR
UK and international business users โ Small business owners calculating business loan repayments, VAT, stamp duty and retirement planning
Students and academics โ Math and science students using percentage, GPA, quadratic solver, square root and fraction calculators
Health and fitness enthusiasts โ People tracking BMI, calorie deficit, body fat, ideal weight and running pace
CalcSphere is used in 80+ countries with strongest traffic from Pakistan, United Kingdom, United States, Australia, South Africa and Malaysia.
CalcSphere's answer:
CalcSphere was built out of frustration with existing calculator websites โ most are cluttered with ads, slow to load, and don't serve non-US audiences well.
The goal was simple: build the fastest, cleanest, most accurate free calculator website that works for everyone โ from a Pakistani homeowner calculating construction costs to a UK small business owner planning a loan.
The Zakat calculator was a particularly important addition. Most online Zakat calculators use incorrect nisab values or don't explain which scholarly standard they follow. CalcSphere's Zakat calculator is built on the verified fatwa of Mufti Taqi Usmani (Fiqhi Muqalat Vol 1, Page 31) and defaults to silver nisab for mixed assets โ making it the most accurate free Zakat calculator available online.
Built with Next.js 14, Tailwind CSS and deployed on Vercel, CalcSphere launched in April 2026 and achieved 100/100 Google PageSpeed scores on both mobile and desktop.
CalcSphere's answer:
CalcSphere is a free tool used by individual users worldwide โ not a B2B SaaS product with named customers
Users include students, homeowners, small business owners, construction contractors, financial planners and Muslim professionals calculating Zakat
Active users in 80+ countries including Pakistan, United Kingdom, United States, Australia, India, South Africa, Malaysia and Bangladesh

LinearB is an engineering productivity platform that provides visibility into developer workflows, automation, and process metrics. It collects data across the entire development lifecycle to diagnose blockers and optimize delivery. One user reports saving 321 developer-hours per month. - Source: dev.to / 3 months ago
Most tools measure half the picture. Traditional metrics platforms like LinearB focus on quantitative signals (DORA metrics, cycle time). Survey platforms like Culture Amp capture sentiment across organizations but aren't developer-specific. DX (founded by DORA/SPACE research creators) combines developer surveys with SDLC analytics. These approaches require deliberate implementation and buy-in. - Source: dev.to / 8 months ago
LinearB is a SaaS solution that retrieves metrics overtime, some of them being used to calculate DORA Metrics. They also have a Youtube channel that advocate for DORA Metrics and more. - Source: dev.to / over 2 years ago
