Common questions
How does a celebrity video call platform protect payments?
In this concept, fans pay into escrow when booking a slot, and funds are held until the call is completed, then released to the celebrity. The design also includes a refund if a call is missed.
What technology powers reliable one-to-one video calls in a mobile app?
The design uses a WebRTC-based video engine with connection monitoring and session management inside a native iOS app. A live timer and escrow status stay visible during the call.
What does it take to build a booking marketplace with live video?
The concept covers a talent directory, availability calendars with timezone handling, escrow payments, WebRTC video and a React web dashboard for talent to manage bookings and earnings. Zovintra can scope a similar marketplace.
