Mobile apps cross-platform or native.

Flutter & React Native for cross-platform speed. Swift & Kotlin native for deep OS integration. We help you pick the right approach — then ship it to the App Store and Play Store. Most teams don't need native; we'll tell you honestly which side you're on.

Our honest read on Mobile App Development.

Four ways to ship a mobile app — cross-platform (Flutter, React Native) or native (Swift, Kotlin). The right pick depends on your audience, your budget, and how deep into each OS you need to go.

Best for
  • iOS + Android from one codebase
  • Native premium experiences
  • Offline-first apps
  • App Store + Play presence
Not for
  • Web-first products (use a PWA)
  • Sub-$15k budgets (use no-code)
  • "Just wrap our website"
  • Simple brochure apps
Most teams don't need native. Flutter or React Native ships iOS + Android from one codebase at roughly half the cost of building twice. We reach for native (Swift / Kotlin) only when the app needs deep OS integration — Apple Watch, CarPlay, Wear OS, ARKit — or when raw performance is genuinely the differentiator. The most expensive mistake we see: building two native apps when cross-platform would have done the job.

The four ways to build mobile — compared

Side-by-side on the 10 dimensions clients actually ask about. No vendor spin — these numbers come from our own builds.

Dimension Flutter React Native iOS Native Android Native PWA / Web
Single codebase (iOS+Android)
Native performance
Deep OS integration
Time to ship both platforms Fast Fast Slow (2x) Slow (2x) Fastest
App Store / Play eligible
Offline-first capability
Hiring market depth (India)
Binary size 30+ MB 20+ MB 5–15 MB 8–20 MB < 1 MB
Maintenance cost Low Low High (2x) High (2x) Lowest
Typical 6-mo build $25–55k $25–55k $35–70k $30–65k $10–25k

* "PWA / Web" = a Progressive Web App or Capacitor-wrapped website. Cheapest and fastest, but limited OS access and weaker App Store presence. Native columns assume building that ONE platform; building both natively doubles cost + maintenance — which is exactly why cross-platform (Flutter / RN) exists.

When we don’t recommend Mobile App Development

Mobile App Development is a great tool — for the right job. Here’s where we’d point you elsewhere, even when it costs us the project.

Web-first product, mobile is a bonus?

PWA (Next.js) or Capacitor wrap

If 90% of usage is on the web, don't build a separate app. A PWA is installable, push-capable, and offline-ready — ships in a fraction of the time.

Validate an idea this month under $15k?

FlutterFlow, Glide, or Bubble

A real custom mobile build is 8+ weeks. For "does anyone want this?", no-code tools ship a testable app in days — then go custom once it's validated.

iOS-only with deep Apple features?

Native iOS (Swift)

If the app lives and dies on Apple Watch, CarPlay, Vision Pro, or ARKit, skip cross-platform. See our dedicated iOS Native page for that path.

"Just turn our website into an app"?

Capacitor / TWA wrapper

Wrapping a responsive site in a native shell is legitimate and cheap — but it's a wrapper, not an app. We'll tell you honestly whether wrapping is enough or you need the real thing.

The stack we’d actually build

A real Mobile App Development project rarely lives alone. Here’s the typical integration stack for a production build.

Mobile App Development stack architecture Mobile App at the center, with 4 integration satellites connected by data flows. Mobile App Cross-platform or native Flutter or React Native Free OSS Supabase or Firebase backend $0–25/mo RevenueCat IAP · Subscriptions $0+/mo Sentry Crash · Performance $0–26/mo
  • Core platform
  • Best-in-class integrations
  • Real-time sync

Total tooling cost: ~$50/mo for a production cross-platform app + backend + crash reporting + IAP. Add Apple Developer ($99/yr) + Google Play ($25 one-time). The real cost is engineering — most cross-platform MVPs ship in 8–12 weeks; native (iOS + Android) doubles that.

What else we can build on Mobile App Development

Mobile App Development is an umbrella — we ship across all four approaches. Here's the breadth of what we build, whichever stack fits your project. Not sure which? The comparison above (and a 15-min call) sorts it out.

The actual offer

Two ways we ship Mobile App Development work.

The deliverable is the same — production-grade Mobile App Development builds backed by ~9 years on the platform. What changes is whose name goes on the project. Pick the engagement model that fits.

For Agencies · White-label

Your name on it. Our hands on it.

We become your invisible Mobile App Development team. You stay client-facing; we handle design, build, and delivery.

  • Custom Mobile App Development builds to your Figma — or full Figma → Mobile App Development end-to-end
  • Your branding on every deliverable; your client never sees our name
  • NDA signed pre-kickoff; collaboration inside your Slack and your Notion
  • Direct line to a senior dev — no handoff to junior offshore
  • Optional white-label maintenance retainer once sites go live

Engagement Hourly or fixed-project. Most agency builds run 2–8 weeks per site, depending on scope.

For End Clients · Direct

From kickoff to handoff. One team.

Full engagement: discovery, design, build, launch, and ongoing care. One point of contact, ~9 years on Mobile App Development.

  • Discovery + content audit + scoped proposal in week 1
  • Figma design + Mobile App Development build with weekly review cadence
  • CMS / admin training + handoff documentation at launch
  • Performance + SEO + accessibility baseline before sign-off
  • Optional care retainer for ongoing iteration after launch

Engagement Project-based or monthly retainer. Most direct engagements run 4–12 weeks end-to-end.

Not sure which model fits? Most engagements start with a 30-min scoping call where we figure that out together.

Engineering rates · USD

Real engineers. India-priced.

All-in rates for Mobile App Development engineers — 3 to 15 years of experience. USD quoted; INR / EUR / GBP available on invoice. Pick your tier and engagement model.

How we calculate this
Hourly
The base. You pay for every hour the engineer logs. No minimum — usually billed in 15-min increments.
Monthly retainer
hourly × 160 hrs/mo × 0.90 — the engineer is dedicated full-time for the month. We discount 10% in exchange for the commitment.
Fixed-cost · scope-first
We don’t quote fixed-cost without scope. After a 15-min scoping call, the typical formula is hourly × estimated hrs with a 10–15% scope-creep buffer absorbed by us. Three months of senior dev typically lands in $15k–$35k depending on platform and complexity — we’ll give you a precise number after we understand the project.
3 – 6 yrs

Mid

$ 24 / hour

Cross-platform developer who ships features across iOS + Android from one codebase.

Best for
  • MVP development
  • Feature iteration
  • Push + IAP integration
  • App Store / Play deploys
Most picked
6 – 10 yrs

Senior

$ 40 / hour

Senior mobile engineer who owns architecture, native channels, and offline-first design.

Best for
  • Production-grade apps
  • Native module bridges
  • Offline-first architecture
  • Custom animations + motion
10 – 15 yrs

Lead · Architect

$ 55 / hour

Mobile architect who designs multi-platform systems and leads the iOS + Android strategy.

Best for
  • Multi-platform architecture
  • Performance + battery audits
  • Team scaling + hiring
  • CI/CD + release pipelines

Rates in USD for cross-platform (Flutter / React Native) — the default for most mobile projects. Native iOS / Android run slightly higher (see those pages). Monthly retainer = hourly × 160 hrs × 90%. 3-month fixed = hourly × 480 hrs, scope creep absorbed. Excludes Apple Developer ($99/yr) + Google Play ($25 one-time). 6+ month retainers get an additional 10% off.

Common questions

Cross-platform or native — how do we decide?

A 15-min call. The default is cross-platform (Flutter or React Native) — one codebase, both stores, roughly half the cost of building twice. We only recommend native (Swift / Kotlin) when the app genuinely needs deep OS integration (Apple Watch, CarPlay, Wear OS, ARKit) or when raw performance is the differentiator. If you’re not sure, that’s exactly what the scoping call sorts out.

Flutter or React Native?

The comparison table above scores them nearly identically — the real deciding factor is your team. React Native if you already live in the JavaScript / React ecosystem (you’ll share types and tooling with your web frontend). Flutter if you’re starting fresh and want pixel-perfect identical UI on both platforms. We ship both; see the dedicated Flutter and React Native pages for the deep dives.

When do we actually need native?

When the app lives and dies on platform-specific features. Native iOS for Apple Watch, CarPlay, Vision Pro, Live Activities, or ARKit. Native Android for Wear OS, Android Auto, home-screen widgets, or deep device integration. If your audience is 80%+ on one platform and needs those features, native is worth the extra cost. Otherwise cross-platform wins.

Can you just turn our website into an app?

Sometimes that’s the honest answer. If your product is fundamentally a responsive website, a PWA or a Capacitor-wrapped shell gets you an installable, push-capable app for a fraction of the cost of a native build. We’ll tell you on the call whether wrapping is enough or you genuinely need a real app — even though the wrapper makes us less money.

Selected work

Our work on this stack is under NDA.

Every engagement we have shipped on this technology has been delivered for clients under mutual confidentiality. We respect that — and we’d rather walk you through the work in a private session than publish a watered-down case study.

What we share privately
  • Architecture diagrams and decision records
  • Performance / scale metrics (before vs after)
  • Stack-specific gotchas we have solved at production scale
  • Code-review samples (sanitized, with client permission)
How to see it
  • 15-minute discovery call — no pitch deck, no qualification gauntlet
  • Mutual NDA in place before any technical walkthrough
  • Live architecture review on Loom or in-person at our Ahmedabad office
  • References from current retained clients on request
