We build cross-platform applications for businesses in Noida and Delhi NCR — one codebase that runs natively on iOS, Android, and the web, delivering the same features and performance across all platforms without the cost of maintaining three separate codebases, and without sacrificing the device integrations your app needs.
Web Development Service #30 / 58
Building separate native apps for iOS, Android, and web means three codebases to maintain, three teams to coordinate, and three sets of bugs to fix every time a feature changes. Cross-platform development with React Native gives you one codebase that compiles to native iOS and Android, with a web version from the same code — without the performance compromises that gave early cross-platform frameworks a bad reputation.
Marketing Wise has delivered 38+ cross-platform applications for startups, D2C brands, enterprise internal tools, healthcare platforms, and B2B SaaS products across Noida, Delhi, and Gurugram. Our cross-platform builds use React Native as the primary framework — it compiles to true native iOS and Android code (not a web view), with full access to device APIs including GPS, camera, push notifications, biometrics, and Bluetooth. For web, we use React Native Web or a shared React codebase so the same business logic and components serve all three platforms.
The cross-platform approach is not a compromise — it is the right architecture when you need to be on multiple platforms simultaneously, when your team will maintain the codebase after delivery, and when your product will iterate frequently. A change to business logic, a new API endpoint, or a UI update is written once and deployed to all platforms in the same release cycle. The cost saving versus three separate native codebases is typically 40–55% on build cost and 60–70% on ongoing maintenance.

No mystery phases. Four gates every cross-platform engagement crosses — from platform strategy to simultaneous iOS, Android, and web launch.
We confirm the target platforms (iOS, Android, web, or a subset), map user journeys per role, design wireframes for all screen states, specify device API requirements, plan the offline architecture, and define the code sharing strategy between mobile and web. Platform-specific UI adaptations are identified before build begins.
Core screens, navigation, authentication, and primary data flows are built and visible on TestFlight and Play Console internal track at the end of each 2-week sprint. Web builds are deployed to a staging URL simultaneously. Sprint reviews cover all platforms — issues on any platform are caught early.
GPS, camera, push notifications, offline sync, payment integration, and third-party APIs are built and tested on physical devices across iOS and Android. Web is tested across browsers and screen sizes. Platform-specific UI adjustments and performance optimisations are applied. Beta testing with real users on all platforms.
App Store and Play Store metadata, screenshots, and compliance declarations are prepared. Both apps are submitted simultaneously. Web is deployed to production. All three platforms go live on the same date. OTA update infrastructure is configured so the first post-launch fix reaches all platforms within minutes of being released.
Mobile app adoption reached 71% of active users within 6 weeks of launch, with mobile users showing 2.3x higher daily active usage than web-only users had prior to the app. A critical bug fix that previously required separate iOS and Android releases was shipped OTA to all users in 4 minutes. Development cost was 44% lower than a quote received for three separate native builds.
The SaaS product existed only as a web app. Customers repeatedly requested iOS and Android apps for field access. The company had received quotes for separate native iOS and Android builds that were cost-prohibitive. They needed a mobile app that maintained feature parity with the web app and could be maintained by their existing 2-person frontend team without hiring iOS and Android specialists.
We built a React Native cross-platform app sharing 87% of code with the existing React web codebase. The mobile app added push notifications, offline capability, and native document scanning (camera-based). The web app was refactored to use the shared component library. OTA updates via Expo Updates allowed the team to ship fixes without store review cycles.

Field data entry accuracy improved from 73% (paper transcription to Excel) to 99% (direct digital entry with validation). Offline mode sustained uninterrupted operations across 6 field sites with no connectivity. Report generation time reduced from 2 days to automated same-day delivery after field data flowed directly into the reporting system.
Field surveyors at 6 infrastructure sites worked in areas with no mobile connectivity for hours at a time. Previous attempts to introduce mobile data capture had failed because apps required an internet connection to function. Data collected on paper was transcribed to Excel at end of day — introducing errors and a 24-hour data lag.
We built an offline-first cross-platform app where surveyors complete digital forms (with photo capture and GPS coordinates) entirely offline. Data syncs in the background when any connectivity is available. The app detected partial sync opportunities — syncing completed form packets when even brief connectivity was available mid-day. Site managers saw incoming data in real time as connectivity permitted.

iOS and Android launched simultaneously on the same day — impossible with separate native builds on the same timeline. Provider app offline capability reduced job loss during connectivity gaps from 8% of jobs to zero. App Store rating of 4.3 achieved within the first 100 reviews.
The marketplace needed to launch customer and service provider apps on both iOS and Android simultaneously within a 16-week window before a committed marketing campaign. Their budget did not allow for four separate native builds (customer iOS, customer Android, provider iOS, provider Android). They needed cross-platform without sacrificing the GPS tracking, push notifications, and camera capabilities their service model required.
We built two React Native apps — one for customers, one for service providers — each running on iOS and Android from the same codebase. The customer app included location-based service search, booking, live provider tracking, and in-app payment. The provider app included offline job queue, navigation, job sheet with photo capture, and customer OTP sign-off. Both apps launched simultaneously on App Store and Play Store.

"They delivered our platform in 12 weeks, on budget and exactly to spec. Weekly demos kept us informed at every stage and the final product matched the requirements document line by line."
"The API architecture they designed handles our peak load without breaking a sweat. We have had zero downtime in eight months of production. The codebase is clean, documented, and our internal team can extend it independently."
"We evaluated three development agencies before choosing Marketing Wise. Their scoping process was the most rigorous — they produced a requirements document that found two gaps we had not identified ourselves."
"The backend they built scaled from 500 to 15,000 daily active users in six months without a single architecture change. That kind of headroom built into the design is rare from an agency engagement."
"Post-launch support was exceptional. They flagged and fixed two edge cases we had not anticipated within 24 hours. The handover package — source code, infra docs, runbook — meant our team could take ownership immediately."

"Custom software built around your exact workflow — not a template, not a shortcut. Engineered to scale, secured from the ground up, and yours outright."
Marketing Wise builds cross-platform mobile and web applications for businesses in Noida and Delhi NCR using React Native — native iOS and Android apps with full device API access, offline capability, push notifications, and GPS, plus a web version from the same codebase. Thirty-eight cross-platform apps delivered across B2B SaaS, consumer marketplaces, field operations, and healthcare.
A cross-platform app for one user type (one set of screens running on iOS, Android, and web) starts at ₹6 lakhs. Apps with two user roles (customer and provider, or user and admin) range from ₹10–18 lakhs. Multi-sided platforms with three or more roles and a backend range from ₹16–30 lakhs. The cost advantage over separate native builds is typically 40–55%.
A single-role cross-platform app takes 10–12 weeks. Apps with two user roles take 13–16 weeks. Multi-sided platforms take 16–20 weeks. Cross-platform does not inherently take less time than native — the time saving comes in future iterations, not the initial build. The simultaneous iOS and Android launch is the primary timeline advantage.
Yes. React Native apps are fully compliant with Apple App Store and Google Play Store guidelines. They are native apps — not web views or hybrid wrappers — and are reviewed and approved exactly like Swift or Kotlin apps. Some of the highest-rated apps on both stores are built with React Native, including apps from Meta, Microsoft, and Shopify. There is no App Store penalty or restriction for React Native.
Yes. Starting with Android only is common when the initial user base is primarily Android — which accounts for approximately 95% of smartphone users in India. Because the codebase is cross-platform, adding iOS is a matter of iOS-specific configuration, testing on iOS devices, and App Store submission — not a rewrite. The iOS release typically takes 4–6 weeks after the Android version is stable.
App Store and Play Store requirements change periodically — minimum SDK versions, privacy permission declarations, and API deprecations. We track these changes and notify clients of required updates before deadlines. For clients on our maintenance retainer, compliance updates are handled proactively. The shared codebase means a compliance update is made once and deployed to both platforms simultaneously.
