Hi sir,
We can help you in designing and developing your chat room application. We have recently worked on "we share" chat application along with audio and video calling functionalities. You also can share images, pdf files, videos, etc.,
Please ping me so that I can share you the APK of the app so that you can have a clear idea on our work.
Will be waiting to hear from you.
Thanks and Regards,
Neeraja
