What is the difference between cross-platform and multi-platform?

In general, there is no difference between cross-platforms and multi-platforms from the users’ side . However, developers choose cross-platform mobile app development if they are using tools that allow them to write codes for many platforms. On the other side, multi-platform means that codes run on many platforms.

developers like such a development because in this, programming is done only once and the app is supported by Android, iOS or Windows.

Cross-platform mobile development is the creation of software applications that are compatible with multiple mobile operating systems . Originally, the complexity of developing mobile apps was compounded by the difficulty of building out a backend that worked across multiple platforms.
