iOS App Development
Native Swift apps for iPhone and iPad, built to Apple's guidelines to avoid App Store review surprises. Best when performance or deep device access matters.
Mobile App Development
What Is Custom App Development?
Custom app development means building a mobile app around your users, your data and your workflows, instead of bending the business to fit an off-the-shelf app or a template builder. Once the project is paid for, the code, the app store listings and the roadmap are yours.
The first real decision is how to build it. Native iOS (Swift) and Android (Kotlin) apps give the best performance and the most direct access to device features. Cross-platform frameworks such as Flutter and React Native share one codebase across both stores, which usually lowers cost and speeds up releases. We recommend one or the other based on the app, not on what we prefer to build.
Not every idea needs a custom app. If customers only need to read information or book an appointment, a well-built mobile-friendly website may do the job for less — and we will say so before quoting.
We build for US startups launching a first product and for established companies adding an app to systems they already run: ordering and e-commerce apps, booking, member portals and internal tools. BaseBites, a US military-base delivery service, has worked with our team on its iOS and Android apps since 2022.

A Mobile App Company in India, Built for US Clients
US companies outsource app development for cost, but the projects that go wrong usually go wrong on communication, not code. So the parts that matter are fixed in writing before work starts: who is on your team, how many hours overlap with your day, where decisions are recorded, and who owns the code.
You can hand us the whole build, or hire mobile app developers who join your own sprint process as a dedicated team. Either way, an NDA is signed before the first project conversation, and ownership of the code transfers to you once the project is paid in full.

iOS, Android and Enterprise App Development
Six ways we build and support apps. Most projects combine two or three — usually a platform choice, the backend behind it, and support after launch.
Android App Development
Native Kotlin apps for Android phones and tablets, tested across the range of devices Android users actually own, and released through Google Play.
Cross-Platform App Development
One Flutter or React Native codebase for both iOS and Android. Usually faster and cheaper to build and maintain, with near-native performance for most apps.
Enterprise App Development
Apps that plug into the systems you already run: company login, role-based access, CRM and ERP data, and admin dashboards for the people managing them.
App Backend & Integrations
APIs, admin panels, payments and third-party services. The app on the phone is usually the smallest part of the system that sits behind it.
App Development Technologies We Use
We pick the stack per app, not one stack for everything, and we tell you why — including when the simpler option is the right one. The backend is chosen for what your own team can maintain after handover, not for what is new.

How We Build a Mobile App
Six stages from first call to the app stores. The two that decide whether a launch date holds are scope sign-off and store review — not the coding.
Discovery & Scope
Who the users are, what version one must do, and what it connects to. Features that can wait go on a separate list.
UI/UX Design & Prototype
Screens and a clickable prototype you can tap through on your own phone before any code is written, so changes cost hours instead of weeks.
App Development
Built in short sprints with a test build on your phone after each one, so you see progress rather than hear about it.
Quality Assurance
Tested on real iOS and Android devices across screen sizes and OS versions, including weak connections and interrupted sessions.
App Deployment
Store listings, screenshots and submission to the App Store and Google Play, including fixes if a reviewer comes back with questions.
Support & Maintenance
Crash monitoring, OS-update fixes and new features after launch, backed by a 30-day warranty on defects from delivery.

Mobile App Development FAQ
Cost depends on screens and user roles, iOS or Android or both, and what the app connects to. Enterprise app development that plugs into a CRM or ERP costs more than a standalone app. We quote a fixed price after a scoping call.
It depends on scope, integrations and how fast decisions are signed off. A focused first version ships far sooner than a full product, which is why we separate must-have features from the ones that can wait. App store review adds time at the end.
Native suits products needing maximum performance or deep device access. Cross-platform suits most business apps: one codebase, lower cost, faster releases. BaseBites, a US delivery platform we built, runs two apps across iOS and Android from Flutter — natively that would have been four codebases.
Yes. Native apps for each platform, or one cross-platform app released to both stores. We handle App Store and Google Play submission either way.
Yes. Dedicated developers join your sprint process, use your tools and report to your team, while we handle hiring and management. It suits companies that already have a product owner and want capacity without permanent hires.
You do. Ownership of the custom code, designs and documentation transfers to you once the project is paid in full. An NDA is signed before any project discussion.
Cost is the usual reason, but it is not what decides whether the project works. What matters is a named team, working-hour overlap, decisions recorded in writing and contractual code ownership. Ask any offshore company to show you those four in writing before signing.
Yes. Every project includes a 30-day warranty on defects in our work after delivery. Ongoing support covers OS updates, crash monitoring, security patches and new features.
