How we build apps
Launch on both app stores without paying for two apps
Most businesses need their app on both iPhone and Android. Building two separate native apps doubles the cost and the maintenance. Cross-platform frameworks like Flutter let one codebase run on both, with smooth, native-feeling performance.
We start by scoping a focused first version, often an MVP, so you can launch, learn from real users and invest in the features they actually use. Design, development and backend happen in one team, with demos every sprint.
When a feature needs deep device access, we add native code for that part, so you get the speed of cross-platform with no compromise where it matters.
What’s included
From idea to app store, and beyond
One team covers product, design, engineering and launch, so decisions move quickly.
Discovery and MVP scoping
We define the core user journeys and features for version one, with a written scope and timeline.
UX and UI design
Clickable prototypes and branded screens tested before development begins.
Cross-platform development
Flutter apps for iOS and Android, with native modules where a feature requires them.
Backend and APIs
Secure cloud backends in Node.js with databases, authentication, admin panels and dashboards.
Integrations
Payments, maps, push notifications, chat, CRM and Zoho, connected and tested.
Launch and support
App store submission, analytics, crash monitoring, updates and new features after launch.

Cross-platform vs native
Cross-platform vs native app development
Both are good choices. The right one depends on your budget, timeline and features.
| Cross-platform (Flutter) | Two native apps (Swift and Kotlin) | |
|---|---|---|
| Codebase | One codebase for iOS and Android | Two separate codebases |
| Cost | Usually lower | Usually higher, roughly two builds |
| Time to market | Faster, ideal for MVPs | Slower |
| Performance | Smooth, native-feeling for most apps | Best for heavy graphics or deep hardware use |
| Maintenance | One set of updates | Every change made twice |
| Best for | Most business, booking, ordering and e-commerce apps | Games, AR and hardware-heavy apps |

FAQ
Frequently asked questions
Can’t find your answer? Book a free call and ask us directly.
Ask us a questionShould I build a cross-platform or native app?
For most business apps, cross-platform with Flutter gives you both app stores for less money and time. Native makes sense for graphics-heavy apps, AR or deep hardware features.
How long does it take to build an app?
It depends on scope. After a discovery call we define the first version and give you a written timeline. A focused MVP is the fastest way to launch.
How much does app development cost?
Apps start at $8,000 for an MVP and $18,000 for a full business app on iOS and Android, with enterprise apps quoted per project, compared with a typical $40,000–$90,000 at New York agencies. You can pay in one go or in equal monthly payments with no interest. Cost depends on features, integrations and backend needs, and we provide a fixed quote for the agreed scope after discovery.
Do you publish the app to the App Store and Google Play?
Yes. We prepare store listings, follow Apple and Google guidelines and handle submission and review.
Who owns the app and source code?
You do. The code, app store accounts and data belong to your business.
Can the app connect to my existing systems?
Yes. We connect apps to CRMs like Zoho, payment providers, booking tools and your own databases through secure APIs.
