I want to build an app that lets users “bank” their mobile data so they can pull it back later instead of buying a new bundle each time. The core idea is simple: whenever a user has unused MBs left on an active plan, the app captures that allowance, stores it securely in the cloud, and makes it available for withdrawal whenever the user’s balance runs low. The first release has to work on both Android and iOS with a consistent UX. Users will sign up with the classic Email + Password flow, so I need solid account creation, email verification, and forgotten-password handling baked in from day one. Key objectives • Data tracking engine that detects remaining mobile data before expiry and transfers it to the user’s personal “vault”. • Cloud-based ledger so that stored data, withdrawals, and transaction history stay in sync across devices. • Intuitive dashboards showing current carrier balance, vault total, and one-tap “redeem” to top up. • Lightweight architecture friendly to low-end phones—nothing should run in the background more than necessary. Deliverables 1. Technical architecture & DB schema covering both platforms 2. Full Flutter or React Native source code (open to your suggestion) 3. REST or GraphQL API with basic admin panel for monitoring vault balances 4. Build & deployment scripts plus TestFlight / Play Store test builds 5. Brief user guide and hand-off documentation Acceptance criteria • Successfully deposits and withdraws data on at least two major carriers during testing • Sync latency under three seconds on 4G • Zero crashes in a 50-user beta over one week I’m happy to answer questions about carrier APIs and provide sample SIMs for integration tests. Looking forward to your proposal and timeline.

Your concept is ambitious and technically interesting, and I can help you turn it into a reliable, carrier-aware mobile product rather than a fragile proof of concept. I’ve built cross-platform mobile apps (Flutter & React Native) backed by cloud ledgers, secure auth, and low-latency sync, with a strong focus on resource efficiency for low-end devices. For your use case, I’d recommend Flutter + a Node.js (NestJS) backend with a transactional ledger design so data deposits, withdrawals, and history remain consistent across devices and sessions. My approach would be: Architect a carrier-agnostic data tracking layer, integrating official carrier APIs where available and fallbacks where permitted Design a cloud ledger (PostgreSQL + Redis) to guarantee atomic deposits/withdrawals and <3s sync Implement secure email/password auth, verification, and recovery from day one Build a clean dashboard showing carrier balance, vault balance, and one-tap redeem Keep background activity minimal to preserve battery and comply with OS limits Deliver test builds (TestFlight + Play internal testing), full source code, and clear hand-off docs I’m comfortable working with telecom APIs, SIM-based testing, and beta validation targets like yours. I can also help define the exact feasibility boundaries per carrier early, so expectations stay realistic. Happy to share a detailed timeline and architecture once we discuss carrier access and regions.

As a experienced Flutter Developer and creator of robust, cross-platform mobile applications, I am confident in my ability to deliver a lightweight, user-friendly and scalable Mobile Data Saver App that aligns perfectly with your needs. My prior work demonstrates my expertise in transitions, API integration, and handling real-time data -- all crucial aspects for your data tracking engine and cloud-based ledger requirements. Beyond just building an asset saving platform, I believe optimizing performance is pivotal. I understand your emphasis on ensuring the app wouldn't unnecessarily run in the background. In my experience with creating solutions for low-end devices while still maintaining high functionality, I can guarantee an app that smoothly adapts to different phones without sacrificing on features. Additionally, I would be able to leverage my knowledge of Firebase to ensure secure storage of user balances and solid account creation, email verification and forgotten-password handling as well as REST/GraphQL API for vault balancing which can be easily monitored via an admin panel. On top of all that, I'd love to collaborate further with you by incorporating AI agents into the system to provide intelligent insights into your users' data usage patterns and optimize their savings. Let's turn this vision into a reality!

This is not a typical mobile app—it’s a carrier-level data management problem, and that’s exactly where I operate. I’ll design and ship a cross-platform Android + iOS app with a secure cloud data ledger, real-time sync, and a lightweight client optimized for low-end devices. I’ll own the architecture, carrier integration logic, backend APIs, admin panel, and store-ready builds (TestFlight + Play Console). Expect clean Flutter or React Native code, rock-solid auth flows, and sub-3s sync even on 4G. I’ve built transaction-driven systems before and know how to make them reliable, testable, and scalable. If you want this executed properly—not experimented with—I’m ready to start.

Hello, I can build this app using Flutter (Android & iOS) with a secure backend and clean, scalable architecture. Before implementation, we’ll first validate the technical feasibility with your carrier integrations, as OS-level access to mobile data is restricted on both iOS and Android. Proposed approach: • Cross-platform Flutter app with Email/Password auth, verification, and recovery • Cloud backend (ledger, vault balance, transaction history, admin panel) • Lightweight UI optimized for low-end devices • Secure APIs with sync under 3 seconds • Test builds for Play Store & TestFlight Important clarifications needed: Do you already have official carrier APIs or partnerships to read and reassign unused data? Should the first release support Android only, or is iOS approval mandatory from day one? Is “banked data” real carrier MBs or a virtual credit system redeemable via partners? Once these are confirmed, I’ll finalize the architecture and timeline. Budget and delivery schedule can be discussed in chat.

The core challenge is creating a seamless, reliable system that accurately captures and manages unused mobile data across carriers without draining device resources or compromising user experience. Missteps here risk data loss, frustrated users, and poor adoption. Failing to synchronise in near real-time or provide rock-solid account security undermines trust and retention. My experience in architecting cross-platform applications with cloud-backed ledgers tackles these exact bottlenecks, ensuring efficient data tracking and intuitive controls that work smoothly on low-end devices. Having delivered similar fintech-grade projects beyond this platform, I offer a strategic introductory rate to build mutual confidence and platform credibility. Let’s clarify any specifics to align on scope and timeline. Liam Jasson
