The present disclosure provides a method for interaction between terminals, implemented by a first terminal. The method includes: acquiring to-be-sent data; sending the to-be-sent data to a second terminal; displaying a display interface; monitoring whether first operation information from the second terminal is received, the first operation information including a processing operation received by the second terminal after the second terminal outputs the to-be-sent data and performed by a user of the second terminal on the to-be-sent data; and updating the display interface according to the first operation information once the first operation information sent by the second terminal is received. The present disclosure further provides an apparatus and a system for interaction between terminals. According to the present disclosure, data can be exchanged between terminals in real time, thereby improving interactivity between users of the terminals.
