What we build
From one idea to both app stores — and the web.
We help you pick the right path, then build it properly: clean code, tested, documented, and ready to grow.
Cross-platform mobile apps
One Flutter or React Native codebase, a native feel on both iOS and Android — faster to build, easier to maintain.
Native apps
Swift and Kotlin when raw performance, device hardware or platform-specific features demand the real thing.
Progressive web apps
Installable, offline-capable web apps that work on any device — no app store, instant updates.
Web applications
Dashboards, customer portals and SaaS-style tools — complex, role-based software that runs in the browser.
App backends & APIs
Authentication, payments, push notifications and real-time sync — the secure services your app runs on.
Security, QA & store launch
Automated testing, hardening and a guided App Store & Play Store submission — shipped right, not just shipped.
Where an app earns its keep
Common things we help clients put in people's pockets.
Booking & appointments
Membership & community
Field & on-site teams
Customer self-service portals
Internal tools & dashboards
Marketplaces & directories
Stack & approach
Proven tools, a process that protects your launch.
We choose the platform for your users and budget — then engineer it with testing and CI/CD from the first commit.

How we work
Prototype early, test on real devices, launch with confidence.
You validate the idea before we build the whole thing — and you see progress every week.
01
Discover & scope
Goals, users and platform choice — then a fixed scope, timeline and quote.
Week 102
Design & prototype
UX flows and UI, plus a clickable prototype so you can feel the app before code.
Week 1–203
Build & test
Sprints with weekly demos, real-device QA, and beta builds via TestFlight / Play Beta.
Week 2 onward04
Launch & iterate
Store submission, monitoring, and a steady cadence of updates and improvements.
Launch + ongoingThe On-Time Delivery Commitment
We agree a delivery date up front and stand behind it. If a milestone we control slips, you're not left guessing — there's a defined remedy, in writing, before we start.

Every client also gets our own branded client app and CRM — a live, white-label platform to track projects, message us, and manage their leads, all under the GigaWebZone brand. It's genuine and demoable.
Distinct from the bespoke app builds above — this is our own platform, shown in a live demo, not a client case study.Platform work

App development FAQs
For most apps we recommend cross-platform (Flutter or React Native): one codebase, both platforms, lower cost and faster updates. We go native (Swift/Kotlin) when you need maximum performance, heavy device-hardware use, or platform-specific capabilities. We'll give you an honest recommendation for your case.
Yes — that's what our discovery phase is for. We help turn a rough idea into a clear scope, user flows and a clickable prototype, so you can validate it before committing to a full build.
A focused MVP typically takes 6–12 weeks; larger apps scale from there. Cost depends on platforms, features and integrations. We lock a fixed scope and quote in discovery so there are no surprises — and we can phase the build to fit a budget.
Yes. We prepare store listings, handle the technical submission and review process for both Apple's App Store and Google Play, and support you through approvals.
Yes — OS updates, bug fixes, new features, monitoring and security are all available on ongoing care plans. Mobile platforms move fast, and we keep your app current.
They're two different things, and we keep that honest. The GigaWebZone client app & CRM is our own branded, ready-to-use platform that every client gets for managing their projects and leads. A bespoke app is custom software we design and build specifically for you and your users. We're happy to demo the former and scope the latter.
