Cross Platform Test Series App

@mrresearcher99

Hello, I have 10 years of experience developing mobile learning and education applications, with strong expertise in React Native, Android, iOS, REST APIs, and web-based admin systems. I can build this test-series platform with separate Practice and Live exam workflows, including timed sessions, automatic submission, instant results, scheduled exams, and controlled retakes. React Native is a suitable choice for maintaining a consistent experience across Android and iOS while keeping performance smooth on mid-range devices. I would implement secure authentication with a two-device limit, protected question/PDF access, real-time participation analytics, notifications, and a modular content structure that can later support video and audio. The admin dashboard would manage tests, questions, PDFs, users, scheduling, and reports efficiently. I’d be happy to discuss the workflow and milestone plan. Best regards

I see you're looking for a cross-platform test series app with specific user limits and a polished interface. And that requirement for each account to be limited to two devices, with the oldest logging out upon a third login, is a key feature that needs careful handling to make sure smooth user experience and security. I'll implement this by setting up a solid authentication mechanism that tracks device logins, and enforces the logout of the oldest device when necessary. For the rest of the app, I’ll make sure the interface is intuitive and responsive, just to focus on smooth navigation and performance. I can have the app ready for you to test first. So you can check everything works as expected before any payment or award. This way, you only commit once you're satisfied with the results. I’m ready to start immediately and can complete this for 9999 INR, looking forward to collaborating on this project, it should be fun! Rajavel - React Native and Flutter Developer

I can implement the complete testing, study-material and administration workflow. Key features I can deliver: • Practice Mode with unlimited attempts and instant results • Live Mode with scheduled start, countdown and one-time attempt restriction • Auto-submit/lock when the timer expires • Admin question-set management and one-click test publishing • PDF upload, tagging, expiry and in-app reader • Architecture ready for future video/audio content • Maximum 2-device account binding with automatic oldest-device logout • Secure APIs and content-access controls to reduce copying/sharing • Real-time participation and performance analytics • FCM push notifications for exams, PDFs and results • Web Admin Dashboard • Play Store & App Store ready builds • Complete source code, API documentation and deployment instructions **Tech Stack:** Flutter, Dart, Firebase/Node.js, REST APIs, PostgreSQL/Firebase and FCM. I’m ready to discuss the test logic, security requirements and timeline.

@abhilashr53

You want a polished, cross-platform test series app where students experience two distinct exam modes, secure study material, and a smooth interface on any Android or iOS device, while you control everything from a clean admin dashboard. Here is my approach. I will build the mobile app in React Native with Expo, giving you true native performance on both platforms from a single codebase. The backend will be Node.js with PostgreSQL, hosted on a scalable cloud instance. For the admin dashboard I will use a React web panel. Key implementation points. Live Mode uses server-authoritative countdown logic so the lock triggers even if a student loses connectivity briefly. Device binding is enforced at the token level with automatic session revocation on the third login. PDF content is served via signed expiring URLs with in-app rendering only, preventing direct download or sharing. The question bank sits behind role-gated APIs. The architecture adds video or audio material later with minimal restructuring. My strengths here are real-time scheduling systems, secure content delivery, and mobile UX that performs well on mid-range hardware. Realistic timeline is ten to twelve weeks for a production-ready build including admin dashboard and QA. One question before I finalise the proposal: do you have an existing brand style guide, or should I propose the visual design direction from scratch?

@iistiakahmed

Hi, your Test Series App is a strong match for our team because this is not just an app UI project. It needs reliable exam logic, real-time scheduling, security, analytics and a powerful admin system. I work with a small 7-member development team covering mobile, web/backend, UI/UX, database and deployment, so we can handle the complete product rather than outsourcing different pieces. We can build: • Android + iOS from one modern cross-platform codebase • Practice Mode with unlimited attempts + instant results • Live Mode with synchronized start/end time, countdown and automatic locking • Secure question bank and PDF study-material system • Maximum 2 devices/account with automatic oldest-device logout • Premium, fast UI optimized for mid-range phones • Admin dashboard for questions, exams, PDFs, expiry/tags and publishing • Real-time participation + student performance analytics • Push notifications for exams, materials and results • Architecture ready for future video/audio learning • Complete source code, documentation, release builds and deployment guidance We can also include useful extras such as detailed exam analytics, ranking/leaderboard options, question-level performance reports and a cleaner administrative workflow without complicating the student experience. I’m newer on Freelancer, so I’m especially focused on building long-term client relationships A chat would be appreciated so I can propose the exact architecture and milestone structure for your app.

@nakabirik

Hello, I have read your project requirement description carfully! The core challenge is making Practice and Live exams behave differently while keeping synchronized timing, one-attempt locking, two-device enforcement and secure study material reliable across Android and iOS. I’d use Flutter for the cross-platform app with a PHP/API backend, keeping test rules, device sessions and exam timing server-authoritative. Practice attempts can remain unlimited, while Live tests will lock attempts and enforce start/end timestamps even after reconnects. PDFs will support secure upload, tagging, expiry and in-app/offline access, with the question bank protected through backend authorization. The admin dashboard will cover question sets, scheduling, participation, performance and push notifications. My mobile/API, MySQL, Docker/CI-CD and production application experience supports this structure. Could you confirm whether the admin dashboard should be a separate web panel or included inside the Flutter app? Looking forward to working with you. Muheebwa

@shuvadeep003

Hi, Your app needs more than a test platform—the key challenge is delivering a secure exam system where Live Mode stays synchronized for every student while Practice Mode remains flexible, and both work smoothly on Android and iOS. I’d recommend Flutter with Firebase for authentication, notifications, and real-time scheduling, backed by a scalable API and admin dashboard. The MVP would include Practice and Live tests, automatic countdown locking, PDF study material with an in-app reader, two-device account management, secure question/PDF delivery, real-time analytics, and push notifications. The architecture will also support future video and audio content without major restructuring. I have around 6 years of freelance development experience in cross-platform mobile apps, backend APIs, Firebase integrations, and deployment. I’ll deliver clean source code, documentation, release-ready builds, and include a post-launch bug-fix support window. I’d be happy to discuss the question-bank workflow, anti-copy strategy, and milestone plan before finalizing the implementation. Best regards, Shuvadeep

@OmarRosariomade

Live Mode is where apps like this break, and it's a timing problem rather than a UI one. If the countdown runs on the phone, a student changes the device clock, or force-quits and reopens with a fresh timer. The remaining time has to come from the server on every sync, and "locks at zero" has to be enforced when the submission arrives, not by the screen going grey. A paper that lands after the window closes gets rejected server-side, or the lock is decoration. The second half of that is signal. Students on patchy mobile data will drop mid-paper. Answers should be written locally the moment they're chosen and flushed to the server against the attempt id, so a lost connection costs nothing and reconnecting doesn't restart anything. Skip this and you'll be granting manual re-attempts after every scheduled exam. One attempt only is worth enforcing as a database constraint on student and test, not by hiding the start button. A reinstall or a second device will otherwise create a second attempt and you'll find out from the leaderboard. Milestone one is auth plus the Live Mode engine with server-held timing. Is the Live paper identical for everyone, or randomised per student? Omar
