Mobile App Development Services
Building separate iOS and Android apps doubles your cost and halves your speed. StellarCode builds cross-platform apps with React Native and Flutter: one codebase, native performance, both app stores. For products that genuinely need platform-specific work — heavy graphics, background hardware access — we advise honestly and build native modules only where they earn their keep.
We handle the full lifecycle: product design, development, App Store and Play Store submission (including the review-rejection wrangling), analytics, crash reporting and post-launch iteration. You talk directly to the engineers building your app, not an account-manager relay.
What you get
Cross-platform iOS & Android apps
React Native or Flutter builds that share 90%+ of code across platforms while feeling native on each.
App Store & Play Store launch
Store listings, screenshots, review compliance and phased rollouts — we carry the app through approval, not just to it.
Push notifications & engagement
Segmented push, deep linking and in-app messaging wired to your CRM so the app drives retention, not just installs.
Offline-first data sync
Local storage and conflict-safe sync for apps that must work in the field, on planes, or on patchy networks.
Payments & subscriptions
In-app purchases, Stripe, and regional gateways — implemented to pass store review and reconcile cleanly with your accounting.
Analytics & crash monitoring
Event tracking, funnels and crash reporting from day one, so decisions after launch are made on data.

Mobile App Development — FAQ
How much does mobile app development cost?
A focused single-purpose app typically runs $6,000–$15,000; a marketplace, delivery or social app with accounts, payments and notifications usually lands $15,000–$50,000. These are commonly 40–70% below US, UK or GCC agency quotes because our engineering hub is in Sri Lanka. You get a fixed quote after a free consultation.
Should I build native or cross-platform?
For over 90% of business apps, cross-platform (React Native or Flutter) is the right call: one codebase, both stores, 30–40% lower build cost and much cheaper maintenance. Fully native development only pays off for graphics-heavy games or apps needing deep, constant hardware access — and we will tell you honestly which side of that line your idea falls on.
Do you handle App Store and Google Play submission?
Yes, end to end. We prepare the store listings, privacy declarations and build artifacts, submit for review, and handle any rejections until the app is live. Both store accounts are created in your name, so you own the listing and its history.
Can you update or rescue an existing mobile app?
Yes. We regularly take over apps whose original developers moved on — upgrading abandoned React Native/Flutter versions, fixing store-policy violations, and restoring broken release pipelines. It starts with a short audit so you know the exact state of what you own before committing to anything.
