CodeMonkey's answer

CodeMonkey was founded in 2014 by Jonathan Schor, Ido Schor, and Yishai Pinchover, inspired by their experiences teaching kids to code through playful activities. They envisioned a platform that would make coding accessible and enjoyable for children, blending real programming languages with engaging, game-based learning. Launched in Israel, CodeMonkey quickly gained global traction, reaching over 34 million students in 206 countries by 2024 . In 2018, it was acquired by TAL Education Group but continues to operate independently, expanding its offerings to include courses in AI, data science, and digital literacy. Today, CodeMonkey remains committed to empowering young learners worldwide through fun and effective coding education.

CalcSphere's answer:

CalcSphere was built out of frustration with existing calculator websites — 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 — 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 — making it the most accurate free Zakat calculator available online.
