Yii2 Default application name is “My Application”. You can change this name by editing the config/main.php. Just add the application name property in Config Array.
NOTE: If you’re using the advanced app you will need to change the frontend and backbend config/main.php files.
$config = [ 'id' => 'basic', 'name'=>'Snippet Guru', ..... ];
You can access site or app name with Yii::$app->name
.
