We build software that just works.
DHB Apps is an independent software studio building efficient mobile and web applications — React Native and Expo on Android and iOS, Next.js on the web. Whichever platform a product lives on, we ship with a relentless focus on performance, simplicity, and user experience.
Our Engineering Philosophy
Good software solves one problem exceptionally well. We do not build Swiss-army-knife applications — we build precision tools. Each product starts with a single, clearly defined user need and is engineered until it fulfils that need with zero friction.
The platform follows the problem, never the other way round. Some products belong in your pocket — we ship those cross-platform with React Native and Expo, dropping into native Kotlin or Swift when performance demands it. Others belong in a browser tab — we build those with Next.js and React. The user experience on screen is always the final arbiter.
Every product ships with WCAG-compliant accessibility and localisation in at least 7 languages — from day one, not as an afterthought. On mobile, that also means full offline support.
Mobile & Web, One Standard
React Native and Expo for Android and iOS, Next.js and React for the browser — one shared engineering standard across every platform we ship to.
Native When It Matters
For tasks requiring direct hardware access or maximum frame-rate fidelity, we write native Kotlin and Swift modules — no compromises.
Resilient by Architecture
Mobile apps work fully without a network connection, and web apps degrade gracefully. State is persisted locally; sync is additive, never a requirement for core functionality.
Privacy by Design
No data leaves the device without explicit user action. Analytics, when present, are anonymised and opt-in only.
What We Build
Our portfolio spans multiple verticals and both platforms — mobile apps and web applications — all united by the same quality bar: snappy, resilient, and free of unnecessary complexity.
Precision Utility Apps
Tools that deliver a single measurement or calculation with sub-millimeter or mathematical exactness. These apps replace physical instruments with software equivalents that live in your pocket.
Conversion & Calculation
Fast, offline-capable converters and calculators for units, currencies, and everyday numeric tasks. Optimised for zero-latency responses, even without internet access.
Daily Productivity
Lightweight apps that replace spreadsheets or generic calculators for specific recurring tasks. Single-session learning curve with no onboarding required.
Interactive Entertainment
Physics-driven UI experiences with algorithmically guaranteed fairness — randomised decision tools built on cryptographically seeded engines for provably unbiased results.
Web Platforms
Full products that live in a browser tab — dashboards, workflows, and subscription platforms built with Next.js and React. Nothing to install, available on every device with a browser.
AI & Automation
Agentic tools that carry out real work on your behalf — research, drafting, scheduling, and publishing — with human review built into the loop rather than bolted on afterwards.
Technology Stack
We use a modern, opinionated stack built around React — React Native on mobile, Next.js on the web — with native modules where throughput demands it.

Shared & Tooling
Global by Default
We ship full localisations in 7 languages from day one — not as a follow-up release. Every string, number format, and accessibility label is language-aware at launch.
