First of all, I want to correct that it is inaccurate to define a spy as a simple synchronized video social software. Tiki starts with synchronous video matching and connects users through matching. It's a purely synchronous social interaction. Spy adopts synchronous+asynchronous mode, which combines one-to-one social mode of synchronous video and social mode of asynchronous short video. The core function of 10 version spy is to connect users one-to-one through video. It focuses on unlicensed deception, allowing users to discover the real other party.
