Web and Mobile Apps That Actually Work at Scale — Not Just in the Demo
We build web applications and mobile apps that hold up under real traffic, look exactly like the design, and don't need a rewrite six months after launch. Weekly demos. Your repo. No surprises.
The Real Problem
Why Most Web and App Projects Go Wrong
You briefed the agency. They built something. It looked fine in staging. Then real users showed up. The app slowed to a crawl on Android. The checkout flow broke on Safari. The mobile layout fell apart on a screen size nobody tested. And every fix took two weeks and a new estimate.
Most web and app projects fail gradually. The first release looks okay. But the codebase is messy, the performance was never properly tested, and the design got "interpreted" along the way instead of actually implemented.
We work differently.
You see a working build every Friday. Not a progress update — an actual clickable product. You can test it, break it, and redirect it before two months of work goes in the wrong direction. When we say pixel-perfect, we mean your designers can open the live product next to the Figma file and find them identical.
What We Build
Custom Web & Mobile App Development Services
From internal tools to consumer-facing apps — we cover the full spectrum of web and mobile development, built around your users and your scale.
Custom Web Application Development
Not websites. Web applications — tools people log into, use daily, and depend on for real work. Clean component structure, well-documented APIs, and a codebase your team can actually hand off without a six-hour onboarding session.
Mobile App Development (iOS & Android)
Native iOS and Android when performance and platform features matter. Every app we ship is tested on real devices, not just simulators. That sounds obvious. It isn't always done.
Cross-Platform App Development
One codebase, both platforms. We use React Native and Flutter where it makes sense and add native modules where it doesn't — so you're not paying for two codebases or compromising on user experience.
Progressive Web Apps (PWA)
A web app that installs on a phone, works offline, and feels like a native app — without the App Store review cycle or the cost of a separate mobile build.
Frontend Development & UI Implementation
Figma to production — without the interpretation layer where designs get adjusted because the developer found them difficult. Responsive across every breakpoint, consistent across every browser, smooth on every device.
Web App Performance Optimisation
We audit, profile, and fix: Core Web Vitals, server response times, bundle sizes, image optimization, caching strategy. The kind of work that makes a measurable difference to retention and SEO both.
Why OrchiX
What “Pixel-Perfect”
Actually Means Here
Every agency uses these words. Here's what they specifically mean when we say them.
Pixel-Perfect Means Designers Sign Off
Not "close enough." We QA against the original designs at every screen size before anything ships. Our developers work directly in Figma. Discrepancies are fixed — not logged as change requests.
Scalable Means 50x Your Current Load
Real scalability is about architecture decisions made early — database indexing, caching layers, stateless services, async processing. We document these so your next hire understands why things were built the way they were.
Weekly Demos, Real Redirects
Every Friday, a working build you can use. If a feature doesn't feel right in the actual product, you redirect it the following sprint — not after a six-month engagement ends.
Shared Repos, Zero Dependency
Your code lives in your GitHub organisation from the first commit. Bring development in-house, hand it to another agency, or give a technical co-founder access — without negotiating a handover.
Our Process
How We Build Web & Mobile Apps
Discovery & Technical Scoping (Week 1)
We map the user flows, define the technical requirements, and agree on what success looks like. You get a scoping document in plain language — no jargon, no ambiguity about what's included.
Design Review & Architecture (Week 2)
We review designs for technical feasibility, flag anything that would create problems in development, and settle system architecture, component hierarchy, API contracts, and third-party integrations.
Sprint Build with Friday Demos (Weeks 3–12+)
Two-week sprints. Working demos every Friday. You test the product as it's being built, catch problems early, and give feedback that actually gets incorporated — not logged in a backlog for later.
QA on Real Devices
Cross-browser testing (Chrome, Safari, Firefox, Edge), cross-device testing on actual iOS and Android hardware, performance testing, accessibility audit (WCAG 2.1 AA), and security review.
Launch & Handover
Staged deployment, real-time error monitoring, and performance tracking set up before go-live. Full documentation of the codebase and deployment process — so any competent engineer can pick it up without calling us first.
Technology
The Stack We Work With
We don't push a single stack on every project. The right technology depends on your performance requirements, your team's existing skills, and what you're building.

Web & App Development Across Industries
Every industry has different performance, compliance, and user experience requirements. We build for those specifics — not a generic template.
Fintech
Trading platforms, personal finance dashboards, lending portals, KYC flows. Performance and security treated as non-negotiable.
Healthcare
Patient portals, appointment booking, telemedicine apps, clinical tools. HIPAA-aware architecture built for non-technical users.
eCommerce & Retail
Custom storefronts, B2B ordering portals, inventory management interfaces, loyalty apps. Fast checkout flows that hold during peak traffic.
Logistics & Field Ops
Driver apps, dispatch dashboards, real-time tracking, offline-capable field tools. Built to run on mid-range Android in poor network conditions.
SaaS & B2B Tools
The core product your customers log into every day. Multi-tenant, role-based, and designed to add features without breaking what's already there.
Media & Content
High-traffic editorial platforms, content management tools, video streaming interfaces, subscription-gated content. Performance at scale is the whole job.
FAQ
Questions About Web & App Development
A focused web application with a clear scope takes 8–14 weeks from kickoff to launch. A mobile app (iOS or Android) typically takes 10–16 weeks. Cross-platform (both platforms, one codebase) adds two to three weeks. These timelines assume design assets are ready — if you need design work done first, add four to six weeks.
If your app needs deep integration with device hardware (Bluetooth, ARKit, high-performance graphics, background processing), native is worth the cost. For most B2B tools and content-driven consumer apps, React Native or Flutter gives you 95% of the native experience at 60% of the cost. We'll give you a specific recommendation after hearing about your use case — we don't have a default answer we apply to everything.
A focused web application runs $5,000–$15,000 depending on scope. A mobile app (single platform) runs $8,000–$20,000. Cross-platform mobile (iOS + Android) runs $12,000–$25,000. These are starting ranges — the actual number comes from a proper scoping session, not an estimate off a brief.
Yes. We work from Figma, Sketch, or Adobe XD files and implement them accurately. We'll do a design review before we start to flag anything that would cause problems in development — responsive edge cases, animation complexity, missing states — and resolve them upfront rather than mid-build.
We do this regularly. We start with a codebase audit to understand what's there, what's broken, and what's safe to build on. You'll get an honest report — not a sales pitch — and a recommended path forward. Some things are worth saving. Some aren't. We'll tell you which is which.
Full stack. We build the frontend, the API, the database, the cloud infrastructure, and the integrations. One team, end to end. If you already have a backend and only need frontend work, we do that too.
