I want a single, seamless way to link up to five Android and iOS phones to mine so I can: • Monitor activity in real time (notifications, usage stats, basic telemetry) • Push or pull files instantly between devices • Remotely adjust key settings—Wi-Fi, Bluetooth, volume, hotspot, etc. I am open to the best technical approach—native apps, a React Native/Flutter hybrid, or another secure solution—as long as it runs smoothly on both platforms and keeps battery impact low. End-to-end encryption and rock-solid permission handling are essential. Deliverables 1. Installable builds for Android and iOS plus source code 2. A quick-start guide showing pairing, everyday use, and revoking access 3. Brief hand-over session (video or live) to walk me through deployment and any future scaling The project is considered complete once I can reliably connect all five devices, perform the three functions above without crashes or noticeable lag, and see clear audit logs of each action.
