Call Re-coding app in ios and android

Develop a cross-platform call recording application for iOS and Android. The app should record all incoming and outgoing call details such as call duration, timestamps, and phone numbers. It should capture this call log data at regular one-hour intervals and securely transmit the anonymized aggregates to a backend server. The server would then compile and store the usage statistics. Key features include initiating audio recording with phone calls, running recording in the background even when the app is closed, and uploading encrypted data payloads on a schedule. Developers proficient in mobile SDKs like Swift, Java and backend services like Node.js are encouraged to bid on bringing this call data capture and reporting concept to life with an eye towards privacy and security best practices.
