What We Deliver

Everything included in our App Development

A complete app development service from discovery to deployment and beyond.

Cross-Platform (Flutter)

One codebase, two platforms. Flutter delivers native-quality iOS and Android apps at a fraction of the cost.

Native iOS (Swift)

Pure Swift and SwiftUI apps for iOS and iPadOS with native performance and full access to Apple APIs.

Native Android (Kotlin)

Modern Kotlin apps with Jetpack Compose, targeting the full Android device ecosystem.

UX-First Design

Every screen is designed for real human behaviour — fast onboarding, intuitive navigation, and zero friction.

Backend & API Integration

REST/GraphQL APIs, Firebase, push notifications, payments (Stripe, in-app purchases), and real-time features.

Store Publishing

We handle the full App Store and Play Store submission process, including ASO, screenshots, and review responses.

How We Work

Our Process

A clear, collaborative process with regular check-ins so you always know where your project stands.

Start a Project
01

Concept & User Research

We map user personas, journeys, and pain points. This ensures every feature solves a real problem — and that nothing unnecessary is built.

User PersonasJourney MappingCompetitive Analysis
02

UI/UX Design

Interactive Figma prototypes following platform guidelines (HIG for iOS, Material 3 for Android). User-tested before a line of code is written.

Development & Sprints

Two-week sprints with TestFlight / internal track builds delivered each sprint. You test on real devices throughout.

Ask Us Anything
Flutter vs native — which is right for my app?
Flutter is ideal for most apps — it reduces cost, ships faster, and delivers near-native performance. Native (Swift/Kotlin) is recommended for apps with heavy platform-specific features like AR, advanced camera processing, or complex hardware integrations.
How long does it take to build a mobile app?
A simple MVP takes 6–8 weeks. A feature-rich cross-platform app typically takes 3–5 months. Enterprise apps with complex backends can take 6–12 months. We'll give you a precise timeline in your free consultation.
Do you handle App Store / Play Store submission?
Yes, fully. We prepare all store assets (screenshots, descriptions, keywords, icons), submit the app, handle review feedback, and guide you through any rejection issues.
Can you build a backend / API for the app?
Absolutely. We build the entire product — mobile app, backend API, database, admin panel, and cloud infrastructure. You get a complete solution, not just a front-end.
What if I already have a design?
Great — we can work from your Figma files. If there are gaps or improvements needed, our designers will flag them as part of our kickoff process.
Do you offer maintenance after launch?
Yes. We offer monthly maintenance retainers covering OS compatibility updates, bug fixes, performance monitoring, and feature additions.
