TorunHero Studio makes small, focused Android apps that keep people away from uncontrolled content, give children a safe bounded environment, and make writing in Bangla easier.
Mohammad Shuvo Kaium — founder and sole developer of the studio. Self-taught programmer of five years, learning entirely on a mobile phone with no PC, no formal training, and no mentor.
No industry background, no formal training — learned from scratch, by breaking things and rebuilding them.
No PC, no mentor — just a phone and a decision to learn programming. Sketchware Pro became the main tool, learning Java hands-on through a block-based editor.
Started from a real problem: uncontrolled access to harmful content. Built real-time, screen-level detection using Android's Accessibility Service, which became the foundation for the studio.
Kids Launcher brought a safe environment for children, and Bangla Hero Keyboard made typing in the mother tongue easier. Also experimented with a dialer app and a math-solving app.
Detection has been extended to Telegram and YouTube Shorts across 33+ languages. Current work focuses on reducing false positives and making Focus Mode's delayed-unblock system more reliable.
Each app is built for one specific problem — not a feature-stuffed general app.
Uses Android's Accessibility Service to analyze on-screen content in real time and detect and block uncontrolled search and video content — including on custom-drawn UI like Telegram, where standard resource-ID matching doesn't work.
Not a surveillance app — a bounded, safe home screen where a child can only reach apps a parent has chosen. Privacy-first by design, not monitoring.
A full custom Android IME built from scratch — a custom Canvas-based wheel for matra selection, voice input, and emoji, all in a dark theme.
The Pro tier of TorunHero, built for people who need stronger protection: a delayed-unblock Focus Mode and tighter uninstall protection so blocking can't be switched off in a moment of impulse.
A step-by-step math solver in Bangla. Layered architecture — MainActivity → MathController → MathEngine — starting with a linear equation solver.
A dark-themed dialer with T9 search, dual-SIM support, and a custom in-call screen. Call log loaded via ContentResolver.
Three principles followed across every project.
Not watching a child or a user in secret — instead building a bounded environment where harmful content has no way in.
From Bangla Hero Keyboard to TorunHero — every app works on-device, with no typing or usage data sent anywhere.
Built around language, network limits, and real device conditions — not another app translated into Bangla as an afterthought.
