iDataGear Inc operates across two areas: McLearn language learning products and Business Intelligence solutions. Intelligence Data Gear means we turn data into intelligence — whether helping people master new languages or helping businesses make smarter decisions.
iDataGear brings over 10 years of experience building data-driven software and mobile experiences. Our language learning apps are developed by native speakers and educators, ensuring cultural authenticity and pedagogical depth. Our BI solutions are backed by proven ETL methodologies, analytics implementation, and enterprise software engineering.
How we work: User research → iterative development → data-driven improvement. Every product undergoes rigorous testing and continuous refinement based on real feedback.
iDataGear is a software team working between Toronto, Canada and Hong Kong, combining three disciplines under one roof: language education, data engineering, and product development. Every McLearn course is written and reviewed by native speakers of Mandarin, Cantonese, and English, and aligned to recognised public standards — HSK for Mandarin, the CEFR (A1–C2) for English, and the Linguistic Society of Hong Kong's Jyutping romanization for Cantonese — so learners always know where they stand against an external benchmark.
The engineering side of the team brings over a decade of experience shipping production data platforms — ETL pipelines, analytics dashboards, and enterprise software — and applies the same discipline to our consumer apps: offline-first architecture, on-device machine learning for privacy (as in Momera.ME's local speech-to-text), and cross-platform delivery on web and Android. We use our own products daily — the same apps we publish are the ones our team learns and journals with.
Our McLearn trademark covers ALL English, Learn Chinese, Learn Cantonese, Xie Zi, and the Great Cantonese Dictionary. Built with cultural authenticity, structured learning paths, and cross-platform accessibility. Developed by language experts and native speakers.
iDataGear specialises in ETL data processing, analytics implementation, and BI dashboards. We help enterprises transform raw data into actionable intelligence — faster pipelines, clearer insights, better decisions.
From strategy sprints to full product builds, we deliver end-to-end software development — web applications, cross-platform mobile apps, and enterprise solutions.
Whether building language apps or BI dashboards, the same principles apply: clarity, quality, and continuous improvement. Our own products are the proof.
