Mobile App Development

Apps users love. Built on iOS, Android, or both.

From a 3-week MVP to a multi-million-user social app — we build mobile products that feel native, run smooth, and scale gracefully. React Native and Flutter for speed. Swift and Kotlin when you need the metal.

Mobile-first engineering with App Store-grade polish.

We've shipped apps that hit #1 in their category, passed Apple's strictest reviews on first submission, and survived viral growth without rewrites. We design for the constraints: battery, network, screen — and we treat performance as a feature, not an afterthought.

  • React Native (Expo or bare workflow)
  • Flutter for pixel-perfect cross-platform
  • Native iOS (Swift, SwiftUI) and Android (Kotlin, Compose)
  • Offline-first architecture with sync engines
  • App Store + Google Play submission, ASO, and review handling

Our Approach

How we deliver end-to-end

01

Product Discovery & UX

User journeys, wireframes, and a clickable Figma prototype. We pressure-test the idea before we touch code.

02

UI Design & Prototyping

Pixel-perfect designs in Figma, motion specs, and a design system that scales as you add features.

03

Engineering Sprints

Weekly TestFlight & Play Internal builds. You see and use the app every Friday — long before launch.

04

QA & Beta Testing

Real devices, edge networks, accessibility, localization. Beta rollouts via TestFlight & Play.

05

Launch & Optimize

Store submission, ASO, analytics dashboards, crash monitoring. We watch the launch metrics with you.

FAQs

Common questions

Should we build native or cross-platform?
Depends. Heavy graphics, ARKit/ARCore, deep system integration → native. Most CRUD apps, social apps, e-commerce → React Native or Flutter saves 40-60% time and money. We&apos;ll recommend honestly after your discovery call.
How long does a mobile app take to build?
MVP (4-6 weeks), production app (8-16 weeks), complex platform (4-8 months). We give a hard timeline after scoping and stick to it.
Do you handle App Store and Play Store submission?
Yes. We handle developer accounts, signing certificates, store listings, screenshots, ASO keywords, and review responses. Most clients get approved on first submission.
What about updates and maintenance?
iOS/Android push two major releases a year — we keep your app on the latest SDKs, dependencies, and design guidelines. Monthly retainer or per-update billing — your call.
Can you migrate our existing app?
Yes. We&apos;ve done native-to-RN, RN-to-Flutter, Cordova-to-native, and full rewrites. We start with an audit so you know exactly what you&apos;re getting.
