Custom App Development — Mobile & Web Applications
From concept to launch, we build powerful applications that transform how you do business. Oxsome's full-stack development team handles everything, from design and backend to security and deployment, so you can focus on running your business while we bring your vision to life.
We specialize in cross-platform development for iOS and Android, delivering native performance from a single codebase. This means faster time to market and a consistent experience for all your users, without doubling your development costs. Our intuitive UX design process includes user research, interaction design, accessibility-first principles, and micro-animations that delight users.
Every application we build runs on powerful, scalable infrastructure. Cloud-based architecture, real-time sync, offline capability, and seamless API integrations ensure your app grows with your business, from 100 users to 100,000. Enterprise-grade security is built into every layer, with end-to-end encryption, secure authentication, compliance readiness, and regular security audits.
We don't disappear after launch. Our ongoing partnership includes app store submission, performance monitoring, feature updates, and ongoing support. Whether it's a customer-facing mobile app or an internal business tool, Oxsome brings your vision to life with enterprise quality at accessible prices.
AI App Builder: Describe It, and We Build It
Most AI app builders hand you a template and a blank canvas, then leave the hard parts (real backends, security, app store approval) to you. Oxsome works the other way around. You describe what the app needs to do in plain English, and our team pairs proprietary AI agents with senior developers to design, build, and ship a real, production application, not a no-code demo that breaks the moment your business grows.
This is the same AI-first approach that powers every Oxsome product. The apps we build plug straight into the Oxsome Command Center, so the website, SEO, advertising, and data services you already run through Oxsome share one login and one AI brain. Your app is not a disconnected island; it is another surface of the platform that runs your business.
AI shows up throughout the build. Our agents help scope features, generate and review code, tune performance, and surface the app in AI search and assistants like ChatGPT alongside your website. The result is a custom app builder experience with the speed of AI and the reliability of a human engineering team standing behind every release.
Frequently Asked Questions
What is an AI app builder, and how is Oxsome different?
An AI app builder uses artificial intelligence to speed up how an app is designed and built. Most tools are self-serve, no-code template systems that leave backends, security, and app store submission to you. Oxsome pairs proprietary AI agents with senior developers, so you describe the app in plain English and get a real, production-ready application, connected to the Oxsome Command Center, rather than a template you have to finish yourself.
How much does it cost to build a custom app?
Custom app cost depends on scope: the number of features, whether it is mobile, web, or both, the complexity of the backend, and any integrations. A focused internal tool costs far less than a multi-feature consumer app with real-time sync and offline support. Because pricing is tied to what you actually need, Oxsome scopes every project individually and gives you a fixed quote after a free discovery call. There are no hidden per-seat fees.
How long does app development take?
A straightforward app can launch in a few weeks, while a feature-rich cross-platform app with a custom backend typically takes a few months from kickoff to app store. Using AI agents alongside our developers to scope, generate, and review code shortens timelines compared with a traditional agency. We give you a milestone schedule up front so you always know what ships when.
Do you build native, cross-platform, or web apps?
All three. We build cross-platform apps for iOS and Android from a single codebase for native performance without doubling costs, native apps when a platform-specific experience is required, and full web applications and SaaS platforms. We recommend the approach that fits your users and budget during the discovery call.
Does the app connect to the rest of the Oxsome platform?
Yes. Apps we build plug into the Oxsome Command Center, the same place you manage your AI website, SEO, advertising, and data services. One login, one AI brain, and your app shares data and reporting with everything else Oxsome runs for you.
Do you support and update the app after launch?
Yes. Launch is the start of an ongoing partnership. We handle app store submission, performance monitoring, feature updates, and support so your app keeps working and improving as your business grows from a hundred users to a hundred thousand.
