Startup MVPs & Consumer Apps
Beautiful, App Store-ready cross-platform MVPs that ship to iOS and Android together — perfect for validating product-market fit without the cost of running two parallel native teams.
Cross-Platform Mobile App Development

Sales, service, and audit apps for travelling teams — offline-first sync, GPS routing, signature capture, photo attachments, and MDM-friendly deployment.
EdTech & Learning Apps
Adaptive video playback, downloadable lessons, quizzes, gamification, and parent dashboards — engineered to be smooth on the entry-level Android phones most Indian students use.
On-Demand Service Apps
Booking, tracking, payments, and ratings — Uber-style apps with maps, real-time location, and dispatch logic deployed across both stores from a single codebase.

Our Cross-Platform Development Process
A six-step delivery rhythm to ship cross-platform mobile apps with the polish, performance, and store-readiness of true native.
Discovery & Framework Pick
We assess your team, performance needs, UI complexity, and integrations — then recommend Flutter or React Native with documented trade-offs (not religion).
UX & Design System
A unified design system that respects platform conventions where it matters (gestures, navigation) while keeping a strong brand identity across both stores.
Cross-Platform Build
Senior-led sprints with weekly TestFlight and Play Internal builds, automated tests for both platforms, and platform-specific code where genuinely needed.
Performance & Polish
Frame-rate profiling, app size optimisation, cold start tuning, image caching, and platform-specific tweaks — so users cannot tell it is "cross-platform".
App Store + Play Submission
Both stores submitted from a single release — privacy nutrition labels, data safety forms, screenshots, age ratings, and reviewer-comm handled.
Maintenance & OTA Updates
OS upgrade tracking, dependency upgrades, OTA updates via CodePush or Expo Updates, store rating monitoring, and feature roadmap support.
Why Choose Hendoi for Cross-Platform Apps
Six reasons to trust your cross-platform mobile programme to a senior-led engineering team in Chennai.
Faster Time-to-Market
One codebase, one team — typically ~40% faster than running parallel iOS and Android native teams. Get to App Store and Play Store in weeks, not quarters.
Lower Total Cost
Lower development cost, lower maintenance cost, and one feature roadmap to manage. Money saved on parallel native teams becomes marketing budget or runway.
Native-Class Performance
Flutter compiles to native ARM; React Native's new architecture (Fabric + TurboModules) gives near-native perf. We profile aggressively to keep 60fps targets.
Identical Brand Experience
Pixel-perfect consistency across iOS and Android — same animations, same fonts, same micro-interactions. Marketing teams love the brand consistency.
Senior Engineering Only
Our cross-platform leads have shipped multiple Flutter and React Native apps to App Store and Play Store. You get judgement, not just code-throughput.
Transparent Delivery
Weekly TestFlight and Play Internal builds, direct Slack/WhatsApp access to engineers, clear SOWs with honest estimates, and predictable monthly burn.
Engagement Models
Pick the commercial shape that matches your cross-platform programme — launch, scale, or consolidate.
MVP Launch
Fixed-scope cross-platform MVP shipped to both stores with analytics, crash reporting, and 30-day hypercare for rating recovery.
- One codebase, two stores
- Analytics + crash reporting
- 30-day hypercare
Product Squad
A senior cross-platform squad working as an extension of your team — flexing capacity with your roadmap, with weekly demos and transparent burn.
- Senior Flutter / RN engineers
- Weekly demos & sprints
- Roadmap that flexes monthly
Native-to-Cross Migration
When you have separate iOS and Android teams burning budget — we migrate to one cross-platform codebase incrementally, screen by screen.
- Incremental migration
- No Big Bang rewrite
- Team consolidation

Frequently Asked Questions
Common questions founders and product owners ask before scoping a cross-platform mobile app project.
Should I choose Flutter or React Native?
It depends on your team and product. Flutter has tighter visual consistency and great performance for content-rich apps. React Native is excellent if you have a JS/TypeScript team and want code sharing with web. We document the trade-offs in discovery and pick what fits your reality.
Is cross-platform as good as native?
For 80–90% of consumer and enterprise apps, yes. Modern Flutter and React Native (with the new architecture) deliver near-native performance. We recommend true native only when you need deep platform integration (ARKit, Core ML, complex AR), maximum battery efficiency, or absolute UX fluidity for gaming-class interactions.
How long does a cross-platform app take to build?
An MVP typically takes 10–16 weeks for both iOS and Android. Larger products with backend, integrations, and compliance scope can run 4–7 months. We share a milestone plan with weekly TestFlight/Play Internal builds.
How much does a cross-platform app cost?
Cross-platform development typically costs 30–50% less than dual-native because of the shared codebase. After a discovery call we share fixed milestone pricing or retainer estimates with every assumption documented.
Can you integrate native modules in cross-platform apps?
Yes — we write platform channels in Flutter and native modules in React Native when we need to access platform-specific APIs (biometric, HealthKit, payment SDKs, BLE devices, AR features). The cross-platform shell stays in Dart/JS while the bridge code stays minimal and well-tested.
Do you handle App Store and Play Store submission?
Yes — App Store Connect setup, privacy nutrition labels, data safety forms, age ratings, screenshot sets, App Tracking Transparency configuration, and reviewer-comm support.
How do OTA (over-the-air) updates work?
React Native supports CodePush and Expo Updates; Flutter supports Shorebird. We configure OTA carefully — within Apple's rules — so you can ship fixes within hours, not days, while staying compliant.
Can you migrate an existing native app to Flutter or React Native?
Yes — we do it incrementally. New screens go cross-platform first; existing screens stay native until they're re-implemented. The team consolidates gradually without a risky Big Bang rewrite.
