If you want to merge mobile phone applications and name them, you can adopt the following methods:

1. Unified brand name: You can consider naming the merged applications as abbreviations of the original brand names or other related names to facilitate users' identification and memory. For example, the merged application will be named "XX", so that users will easily associate with the original brand when using it.

2. name of merged features: the merged application can be named as a name that combines two or more application features to show the features and advantages of the new application. For example, name the merged application "XX+YY" or "XXYY" so that users can know the characteristics of the new application at a glance.

3. Focus on function name: The merged application can be named as the main function name provided by the application to highlight its characteristics and value. For example, name the merged application "XX Live" or "XX Shopping" so that users can find the functions they need more quickly.

in either case, the name selection should be consistent with the brand image, characteristics and target users of the new application. In addition, make sure the name is simple and easy to remember and search. At the same time, the name of the new application can also be the best choice through market research and user feedback.
