I would like to hire a professional developer/team that can develop an app for smartwatch. Below are the initial summarized requirements:


To connect smartwatch with cellphone (Android/IOS) using Bluetooth to be able to share data such as:

Make & receive WhatsApp calls using the watch

I need to know a rough estimate:
