Mobile App Similar to Astro Talk or Guruji Astro

We are looking for company / person who has already developed / designed applications like Astro talk and Guruji or other Astrology app and have made a successful live on the play store and app store. We are interested to purchase the same codes for both platform along with the web version and will be launching the app after making necessary changes in the UI/UX.

The mobile application must have a Chat and voice calling feature in built.

Please reach out to us with the price if anyone has developed the same application.
