About Mayra
Mayra is an entrepreneur and product builder based in New York, United States of America. He is the founder and creator of iCalcApp — a free online calculator platform designed to make everyday financial, health, and mathematical calculations fast, accurate, and accessible to everyone without requiring signups, subscriptions, or technical knowledge.
With a background in technology and product development, Mayra built iCalcApp after observing that most online calculator tools were cluttered with ads, difficult to navigate on mobile devices, or provided results without any meaningful context or explanation. His goal was to create a platform that not only gives the correct answer but also helps users understand what the answer means and how to use it.
Why He Built iCalcApp
The idea for iCalcApp came from a personal frustration. While researching a home loan, Mayra found that most online EMI calculators gave a number without explaining how the EMI was split between principal and interest, how the total interest changed with different tenures, or what a realistic amortisation schedule looked like. He found the same problem across health tools, percentage calculators, and unit converters — tools that gave numbers without context.
iCalcApp was built to fix that gap. Every calculator on the platform is designed around three principles: accurate formula implementation, clear explanation of the result, and practical guidance on what to do with the information. The platform is built to serve students studying for exams, professionals making financial decisions, fitness enthusiasts tracking health metrics, and anyone who needs a reliable calculation quickly.
Areas of Expertise
How iCalcApp Ensures Accuracy
Every calculator on iCalcApp uses formulas sourced from authoritative references. Health calculators are built on WHO and CDC guidelines. Finance calculators follow standard banking mathematics. Tax tools are based on official government rate schedules. Each calculator is manually tested against known values before publication.
When formulas or rates are updated — such as revised GST slabs, new income tax brackets, or updated WHO health benchmarks — the affected calculators are updated promptly. Users can report any discrepancy through the Contact page and the team investigates and responds within 48 hours.
All calculations run in the user's browser — no data is sent to any server, ensuring complete privacy for sensitive financial and health inputs.
Editorial Responsibility
Mayra is responsible for the accuracy and quality of all content on iCalcApp. This includes reviewing calculator formulas, approving new tools before publication, writing and editing the blog articles that explain calculation concepts, and responding to user feedback about formula accuracy or content quality.
The iCalcApp Editorial Policy documents the standards applied to every calculator and article on the platform, including the sources used, the update process, and the disclaimer standards.
