I need a web-based or desktop based application, similar to the WhatsApp web, I will add contacts, able to see the whats app profile and details.
In this system, I will add contact numbers.
This system will fetch user profile and details
No other function needed(like chat, share, etc - not needed)
Not on the phone. It can be web based or desktop based. Even your development environment is ok for me, I can install it on my machine.
