Mobile App Development

Q: Do you build native or cross-platform apps?

We build both, but recommend cross-platform (React Native or Flutter) for most projects because you ship to iOS and Android from a single codebase — meaning roughly half the time, half the cost, and one feature roadmap instead of two. We use native (Swift / Kotlin) when the project specifically needs platform-specific capabilities or maximum performance.

Q: How long does mobile app development take?

An MVP typically ships in 8–12 weeks. A full-featured app with backend integration, auth, payments, and push notifications usually runs 3–5 months. App Store and Play Store review adds 1–2 weeks at the end. We work in 2-week sprints so you see real progress every fortnight.

Q: Do you handle App Store and Google Play submission?

Yes — full submission lifecycle. We prepare store listings, screenshots, privacy policies, age ratings, app signing, and handle the review process including responding to rejections. You'll get an app live on both stores under your developer account, not ours.

Q: Can the mobile app share a backend with our web app?

Yes — that's the most common pattern. We design a single REST or GraphQL API that both your web app and mobile app consume. Authentication, business logic, and data stay in one place; web and mobile become two front-ends to the same backend.

Q: What about ongoing updates and OS changes?

iOS and Android release new major versions every year, and they regularly deprecate APIs. We offer maintenance retainers that cover SDK upgrades, OS compatibility, bug fixes, and minor feature updates — so your app stays current and passes future App Store reviews without firefighting.

Q: Do you provide app design as part of the build?

Yes. Mobile UX is fundamentally different from web UX — gesture patterns, screen sizes, platform conventions all matter. Our UI/UX designers work with the development team from day one to create app screens that feel native to each platform while staying on-brand.

Q: How much does mobile app development cost?

Cross-platform MVPs typically start from USD 8,000 and scale with complexity. Native iOS + Android (separate codebases) is roughly 1.6× that. Request a quote and we'll give you a transparent breakdown based on your specific app requirements.

Why cross-platform wins for most projects

Built once, shipped twice

Native iOS + native Android means two teams, two codebases, two release schedules, and twice the cost. Cross-platform — done right — ships to both stores from a single codebase with native performance. Here's the difference it makes.

Without cross-platform expertise

Native iOS + native Android means 2× the cost and timeline
App Store rejections and policy changes blocking launch
Slow, janky apps that drain phone batteries
Backend not built for mobile (no offline, no real-time)
No clear path from prototype to App Store

How we ship mobile

From first whiteboard sketch to live in the App Store and Play Store — here's the process.

Prototype & validate

Interactive Figma prototypes you can tap through on your own phone before a single line of code is written. We validate the flows, confirm the scope, lock the design.

Build the MVP

Cross-platform build in React Native or Flutter — single codebase, both stores. API integration, auth, push notifications, offline sync, analytics. Working app in your hands every 2 weeks.

Ship & maintain

App Store + Play Store submission, listing optimisation, response to review feedback. Then ongoing maintenance — SDK upgrades, OS compatibility, new features as your business grows.
