I’m putting together a truly native mobile experience for both iOS and Android that pulls together information my audience currently has to hunt for in several places. The core of the project is an aggregation engine that will: • fetch Facebook and Instagram feeds through their official APIs • call Honeycomb (and similar) endpoints to surface product listings, blog posts and user reviews All content needs to land in a single, well-structured feed that updates automatically and can be filtered by source or content type. Your job starts with choosing the best native stacks—Swift for iOS and Kotlin for Android are my default expectations, but I’m open to proven alternatives as long as the final apps feel fully native and meet the respective store guidelines. You’ll handle secure OAuth flows, efficient background syncing, pagination, basic offline caching and a clean, modern UI that keeps latency low even when multiple sources refresh at once. Deliverables 1. Two store-ready apps (iOS & Android) built from the same design system 2. Source-controlled codebase with clear documentation for API keys, environment variables and build steps 3. A lightweight backend layer (if needed) to normalise responses from the various APIs 4. Brief hand-off session and a short PDF that covers architecture, third-party libraries used and future extension points Acceptance is complete when I can install both apps, connect my test accounts, see Facebook, Instagram and Honeycomb data merged in real time, and pass App Store / Google Play review without issues.

Hi There, 1.I’m putting together a truly native mobile experience for both iOS and And... ==> We got your idea about creating a single feed from Facebook, Instagram, and Honeycomb. This is a great concept to simplify things for your audience. We have worked on similar data aggregation apps before. One interesting feature we built for a past project was a smart feed that learned which content type a user preferred and showed that more often, without them needing to filter manually. We are very comfortable building with Swift for iOS and Kotlin for Android to get that truly native performance you want. We will handle all the technical details like secure logins, background data updates, and offline access to make sure the app is fast and smooth, even with all the data coming in. We understand the deliverables clearly. We will provide two polished apps, clean source code with proper documentation, and a lightweight backend to manage the different data sources. ## Queries : 1. When a user applies a filter to the feed, should that filter setting be saved for their next session? ## Initial Project Structure : - Splash - Connect Accounts - Main Aggregated Feed - Content Detail - Filter Options - Settings We use advanced AI tools (Cursor, Claude, ChatGPT) to speed up coding and reduce manual work hours. We pass these time-savings to you, providing a high-quality app at a very competitive price. Waiting for your reply. :-) Regards, Ghanu & Samir. KESHAV INFOTECH

Hi there, I’ve read your Cross-Platform Data Aggregator App brief and I’m confident I can deliver two fully native experiences (iOS with Swift and Android with Kotlin) that securely fetch Facebook and Instagram via official APIs, harmonize product listings, blog posts, and reviews from Honeycomb-like endpoints, all into a single, live-updating feed with filtering by source or content type. I’ll design a shared design system and implement a lightweight backend to normalize responses, with secure OAuth, efficient background syncing, pagination, and offline caching to keep latency low during multi-source refreshes. Deliverables align with your list: two store-ready apps, a well-documented codebase for API keys and env vars, a lightweight backend, and a concise hand-off PDF covering architecture and extensions. Proposed timeline: MVP in about 4 weeks, with another 2 weeks for polish and QA; I’ll adjust after scope confirmation. What is the single most important constraint or KPI for the MVP so I can scope precisely? What are the exact API rate limits for Facebook and Instagram, and policy constraints? Which Honeycomb-like endpoints will be used, and are there other data sources? Are there any extra authentication needs beyond OAuth? Preferred backend approach: serverless vs microservice? Caching strategy and offline data requirements? Minimum supported OS versions and device constraints? Target feed latency and refresh cadence? Push notifications requirement and event

Hello There!!! ⚜⭐⭐⭐⭐⚜(( Build a fully native app that unifies Facebook, Instagram and Honeycomb data in one smart feed ))⚜⭐⭐⭐⭐⚜ Your idea of bringing scattered content into a single real time mobile experience is powerful. You need two truly native apps that feel smooth on each platform while handling OAuth, background sync and API aggregation reliably. I have strong experience designing Swift and Kotlin solutions with clean architecture, secure token flows and efficient caching so latency stays low even with multiple sources. My plan is to create a small normalisation layer, structured pagination and a shared design system to keep both apps consistent. Most important features 1. Secure API integration with Facebook, Instagram and Honeycomb 2. Auto updating unified feed with filters by source and type 3. Offline caching and store ready native interfaces I would love to learn more about your preferred design style and timeline so we can shape a clear roadmap together. Warm Regards, Farhin B.

Hi I can build fully native iOS and Android apps using Swift and Kotlin (or equivalent native-quality stacks) to aggregate Facebook, Instagram, and Honeycomb data into one clean, unified feed. The core technical challenge is merging multiple API sources smoothly while keeping UI latency low during background syncs, pagination, and OAuth-secured requests. I address this by structuring a lightweight normalization layer and efficient caching logic so content stays fast, consistent, and filterable across sources. Your requirement for a single design system fits well with my experience delivering parallel native apps that pass App Store and Google Play review reliably. I also ensure secure credential handling, stable refresh cycles, and intuitive filtering for different content types. With clear documentation and a structured codebase, you’ll have everything needed for future expansion. I’m confident I can create a polished, native experience that consolidates all your channels seamlessly. Thanks, Hercules
