Mobile and product apps, built once, maintained always.
Cross-platform iOS and Android apps with React Native and Expo, plus the APIs, infrastructure and store management to keep them shipping. The same studio that designs and runs your web stays on for mobile.
From MVP to App Store, and the long road after.
Cross-platform mobile
iOS and Android from one React Native codebase, faster to ship, easier to maintain.
Product apps
Consumer apps, B2B field tools, internal staff apps, designed for daily use.
API & backend
REST or tRPC APIs, Postgres, auth and background jobs, the parts a mobile app actually needs.
App Store release management
TestFlight, internal testing tracks, app store assets, review submission and post-release patches.
Native modules where needed
When React Native is not enough, payments, biometrics, deep camera, BLE, we bridge to native.
Long-term support
OS upgrades, dependency bumps, store policy changes. Mobile apps need ongoing care; we provide it.
App development, common questions.
Do you build native iOS / Android, or cross-platform?
+
We default to React Native with Expo for most product apps, one codebase, faster delivery, easier maintenance, and 95% of the user experience of fully native. When a project needs deep native integration (high-performance graphics, complex BLE, niche hardware), we either bridge native modules or recommend a native build, whichever is honest for the scope.
How much does it cost to build a mobile app in India?
+
A focused MVP mobile app from RoseLeap typically starts at ₹6-12 lakh for a single-platform launch with auth, a handful of screens and an API. Cross-platform launches (iOS + Android together) often add 20-30%, not 100%. Complex marketplaces or social apps scale into the ₹25-60 lakh range. We share a fixed quote per phase.
How long does it take to build and launch an app?
+
A focused MVP runs eight to sixteen weeks from kickoff to store submission. App Store and Play Store review adds a few days to a week. Larger products are scoped in two- to three-month phases with a working release at the end of each.
Do you handle App Store and Play Store submissions?
+
Yes. We manage TestFlight, internal testing tracks, asset preparation, store listings, screenshots, review responses and re-submissions. You provide the developer accounts (which you own); we operate them.
What happens after launch? Do you maintain apps?
+
Yes, most clients move into a monthly retainer covering OS upgrades, dependency updates, store policy changes, new features and bug fixes. Mobile maintenance is non-negotiable, stores break apps that go untouched for too long.
