I am reviewing google assistance because I am using it . I can launch google assistance by holding my home button. Its being very usefull sometimes when you want to search something quickly.
Concept of this app is to answer the question of the users and to do some easy task by only saying. For eg. Google call rajesh. Only saying this you can easily call rajesh.
Layout and design is simple with showing voice reader.
Features such as voice recognition is good but need some more work on it.
Its usefull for quick answers and all jobs like calling etc.
