I have a fully-working messaging platform built with React and Firebase. Now I need the same product delivered as truly react native apps for both iOS and Android. Every screen, animation, colour and interaction must match the current design pixel-for-pixel, so you will be working from the existing UI as the definitive reference. Functionality and flow needs to remain unchanged—real-time chat powered by Firebase, user authentication, media uploads, push notifications and all current edge-case flows must carry over seamlessly. On top of that, integrate in-app subscriptions using each store’s preferred system so users can choose either a monthly or an annual subscription

⭐️⭐️⭐️ React Native Migration of Firebase Messaging Platform (iOS & Android)⭐️⭐️⭐️ I will convert your existing React + Firebase messaging platform into fully native-grade React Native applications for both iOS and Android, ensuring pixel-perfect consistency with your current UI as the source of truth. The goal is a seamless transition where no functionality is lost and the user experience feels identical across web and mobile. The migration will preserve your full real-time chat system using Firebase, including authentication, messaging flows, media uploads, and all existing edge-case handling. I will ensure stable performance and consistent synchronization across devices with proper offline/online state management. Push notifications will be implemented for both platforms using Firebase Cloud Messaging (FCM), ensuring real-time delivery of messages and alerts. All animations, colors, spacing, and interactions will be matched precisely to your current design system. Let’s chat… Thanks

Hey, I will convert your React web app into true React Native apps for iOS and Android — real-time chat, authentication, media uploads, push notifications, and in-app subscriptions — all matching your current UI pixel-for-pixel. For subscriptions, I will integrate RevenueCat to handle both App Store and Google Play billing from a single SDK. This abstracts away the differences between Apple's StoreKit and Google's Billing Library, simplifies receipt validation, and gives you a unified dashboard for subscription analytics without maintaining two separate payment flows. Questions: 1) Are you using Firebase Cloud Messaging for push notifications already, or is that a new addition? 2) Do you have an active Apple Developer and Google Play Console account set up for deployment? Looking forward to potentially working together. Thanks, Kamran

Hi there To convert a working React/Firebase messaging platform into real iOS and Android apps, the most critical part is preserving the existing chat behavior while recreating the interface accurately in React Native. I’ll approach this by mapping every current screen, animation, color, interaction, Firebase flow, media upload path, notification state, and edge case before building the mobile version. The conversion needs careful handling because messaging apps can look correct but fail around real-time sync, unread states, background notifications, media permissions, subscription access, and offline reconnect behavior. This means I understand the goal is not a redesign or a wrapper. It needs native-feeling React Native apps that match the current product, keep Firebase chat stable, and support monthly and annual in-app subscriptions through Apple and Google systems. My process starts with UI and Firebase flow audit, then moves into React Native implementation, push notifications, subscriptions, QA, store readiness, and handoff notes. If it aligns with you, let’s discuss in detail via private chat.

You already have a working React + Firebase messaging platform, and now you need it rebuilt in React Native with identical UI/UX across iOS and Android. The goal is a pixel-perfect version that preserves real-time chat, media flows, and onboarding without behavioural drift. I would recreate the app in React Native using Firebase Auth, Firestore listeners and Storage for media, reusing the same data model to avoid migration risk. Push notifications will be wired via FCM/APNs, and I’ll align animations and spacing to match the current UI exactly using shared design tokens. Subscription system integrated with App Store and Google Play billing, with server-side validation to prevent edge-case abuse. Deliverable will behave as mobile parity of your existing system with no functional regression. Q1: Do you want shared backend or mobile-specific changes in sync or caching? Q2: Should subscriptions unlock features across web and mobile under one account system? Q3: Any existing animations or gestures that must be replicated exactly (swipes, transitions, haptics)?

Hi there, I will rebuild the app in React Native against your existing UI: real-time chat via Firebase, auth, media uploads, push via FCM with APNs bridge, and edge-case flows preserved. Subscriptions integrate with monthly and annual tiers per store. For subscriptions, I will use RevenueCat over raw react-native-iap. RevenueCat handles receipt validation, server-side entitlements, restore-purchase, family sharing, and cross-store reconciliation that a manual build writes by hand. At this budget, the time saved is real. Questions: 1) Apple Developer and Google Play accounts ready, or in scope? 2) Existing Firebase project transferable, or fresh project for native? 3) Subscription structure: one tier monthly/annual, or multiple? Looking forward to your response. Best regards, Faizan

Hi, I can convert your existing React and Firebase messaging platform into true React Native apps for both iOS and Android while keeping the current UI, animations, colors, and user interactions matched as closely as possible to the existing product. The main focus would be preserving the same real-time chat flow, authentication, media uploads, push notifications, and edge-case behavior without changing how users already experience the platform. I have strong experience with React Native, Firebase, mobile authentication, real-time database flows, storage handling, push notification setup, and in-app subscription integration. I would first review the current web app structure, map each screen and interaction, then rebuild the mobile version cleanly with proper native behavior for both platforms. Would you like the first milestone to focus on pixel-perfect UI conversion first, or should we start with Firebase chat and authentication flow before polishing the interface? Thanks Oleksandr
