Hello,
As an expert developer, I can create a simple app that allows two users to make voice calls to each other using any VoIP SDK. The app will also have a feature to record and save the call recordings locally.
We will use advanced technologies and programming languages such as React Native, Node.js, and WebRTC to build the app. The app will be developed for both iOS and Android platforms, and will have a simple, user-friendly interface that allows users to easily make and receive calls.
To ensure the app is secure, we will use encryption technology to protect the calls and call recordings from unauthorized access. The app will also be designed to comply with applicable laws and regulations.
In terms of call recording, we will implement a feature that allows users to start and stop recording calls, with the recordings saved locally on the user's device. Users can access these recordings at any time from within the app.
We will also provide maintenance and support services to ensure that the app remains up-to-date and continues to perform optimally.
Thanks,
