Overview
Your web or mobile app is often the first real conversation a customer has with your business, and increasingly it's where the business actually happens. We build products that make that moment count: fast, accessible, and engineered to scale across every screen, with the kind of polish that makes people trust the product behind it.
On the web we pair thoughtful UX with solid architecture — React and Next.js front ends, secure APIs, and data models that won't fight you as features grow. On mobile, most products ship faster and cheaper cross-platform with React Native, sharing one codebase across iOS and Android; when performance or hardware access demands it, we go fully native with Swift or Kotlin. We'll tell you honestly which path fits your product and budget.
We own the full journey: discovery and UX, design, development, launch, app store releases, and the iterations that follow. We ship early, measure honestly against real usage, and refine relentlessly — because the version that wins is rarely the first one, and a product is never really finished, just continuously improved.
Capabilities
What we deliver.
Responsive web apps
Modern, performant front ends built with React and Next.js that look and work right on every screen, from phones to ultrawide displays.
Cross-platform & native mobile
iOS and Android from one React Native codebase that feels genuinely native — or fully native Swift and Kotlin where performance and hardware access make it the right call.
APIs & backends
Secure, well-documented services, authentication, and real-time infrastructure that power your web and mobile apps reliably at scale.
Performance & accessibility
Core Web Vitals, smooth mobile interactions, and WCAG 2.1 AA accessibility engineered in from day one, with budgets so speed doesn't quietly regress.
App store delivery
We manage submission, review, signing, provisioning, and staged rollout end to end — including the bits that trip teams up on their first release.
Monitoring & iteration
Crash reporting, performance and usage analytics, and a release cadence that turns real-world feedback into steady improvement.

“The TechknockLabs team supported our developers as full-stack engineers in Node.js and React for almost a year. I'd highly recommend them to anyone considering them for a project.”
Web app, mobile app, or both?
It depends on where your users are and what they need to do. Many products start with a responsive web app and add mobile once usage proves it out; others are mobile-first from day one. In discovery we'll give you a straight recommendation based on your users, budget, and roadmap.
Cross-platform or native mobile?
Most products ship faster and more cost-effectively cross-platform with React Native, and modern tooling means it genuinely feels native. We go fully native when performance, heavy animation, or specific hardware demands it — and we'll tell you which fits your case.
Can you improve our existing site or app?
Yes — a lot of our work is exactly this. We audit performance, stability, UX, and architecture, fix what actually moves the needle, and lay out a path for the rest. You don't need a rewrite to get a meaningfully better product.
Do you handle app store submission?
Yes — store listings and assets, review submissions for Apple and Google, code signing, provisioning, and staged rollout. We've been through the rejections and edge cases, so your launch isn't where you learn them.
Who owns the code and how is handover managed?
You own the code outright. We keep it clean, documented, and covered by tests, and we hand over with the context your team needs — or stay on to support and extend it if you'd rather we did.
