Overview

Digital products your customers enjoy using

We create modern websites and mobile applications combining responsive design, seamless functionality, and high-performance development that grows with your business.

Web and app development is how your business shows up online: the website people find on Google, the store they buy from and the app they open every day. At Bits Collision we design and build responsive websites, Android and iOS apps, e-commerce platforms and progressive web apps that are fast, secure and simple to manage.

We work with startups launching their first product, established brands refreshing an outdated site, and growing businesses that need a mobile app to serve customers on the go. Whether you need a marketing website in weeks or a feature-rich app built over several releases, we shape the plan around your goals and budget.

Good development pays for itself. A faster, clearer website converts more visitors, a well-built app keeps customers coming back, and a proper content management system lets your team update content without waiting on a developer. We build for today's launch and for the features you will want next year.

What we offer

What our web and app development covers

From a single landing page to a multi-platform product, every build is responsive, accessible and optimised for search from day one.

Responsive Website Development

Websites that adapt perfectly to phones, tablets and desktops, built with modern frameworks for fast load times and strong Core Web Vitals. We handle everything from information architecture to on-page SEO, so your site is easy to find and easy to use.

Android & iOS App Development

Native and cross-platform mobile apps for Android and iOS, designed around how your customers actually use their phones. We take care of app store submission, push notifications, analytics and the back-end services your app depends on.

E-commerce Solutions

Online stores built to sell, with smooth product browsing, secure checkout, payment gateway integration and inventory management. Whether you need a custom storefront or a Shopify or WooCommerce build, we focus on the details that raise conversion rates.

Progressive Web Apps (PWA)

Progressive web apps combine the reach of a website with the feel of a native app: installable, fast and able to work offline. They are a cost-effective way to reach mobile users without maintaining separate Android and iOS codebases.

CMS Development & Integration

Content management systems your team can actually use, whether that is WordPress, a headless CMS or a custom admin panel. We integrate your CMS with your CRM, marketing tools and analytics so content, leads and data stay in sync.

How we work

How we build websites and apps

A structured process means fewer surprises. You review designs before development starts and see working builds throughout.

  1. Discovery

    We learn about your business, audience and competitors, and define the pages, features and integrations your product needs.

  2. UX & Visual Design

    Wireframes and high-fidelity designs for every key screen, reviewed with you before any code is written.

  3. Development

    Front-end and back-end development in short sprints, with a staging link so you can test progress at any time.

  4. Testing & QA

    Cross-browser, cross-device and performance testing, plus accessibility and SEO checks before anything goes live.

  5. Launch

    We deploy your site or publish your app, set up analytics and monitoring, and make sure everything runs smoothly.

  6. Support & Growth

    Ongoing updates, new features and performance improvements as your audience and your ambitions grow.

FAQ

Web and app development FAQs

Can't find what you're looking for? Our team answers every enquiry within one business day.

A marketing website usually costs far less than a custom mobile app or an e-commerce platform with integrations. After a short discovery call we give you a clear, itemised estimate, and we can phase the work so you launch sooner and add features over time.

Most business websites launch in 4 to 8 weeks. Mobile apps and larger web platforms typically take 3 to 6 months, depending on features and integrations. You will see progress on a staging link throughout.

It depends on your users and features. Cross-platform frameworks like Flutter or React Native suit most apps and cut cost, native apps suit heavy device features, and a progressive web app is often the fastest, most affordable way to reach mobile users. We recommend the right option during discovery.

Yes. Every website we build is fully responsive and includes technical SEO foundations: fast loading, clean URLs, metadata, structured data and accessible markup, so search engines can crawl and rank it properly.

Yes. We connect your site to an easy-to-use content management system and show your team how to edit pages, publish posts and manage products without touching any code.

Yes. We prepare store listings, screenshots and privacy details, handle the submission and review process for both Apple's App Store and Google Play, and manage updates after launch.
