iPhonefans @khucthuydu18 Why don't you try the official one on Google play store? It seems free. You can download the attachment file if you have goldendict app on your phone. Code: http://www.mediafire.com/file/czmyttyui9l/Grammar_in_use_new_version.bgl/file
iPhonefans @khucthuydu18 So download goldendict app from Google play store and then copy the above file to the folder "Goldendict" in the SD card of your phone. Open Goldendict and index this file. You will have Grammar in Use. Use it like a dictionary. Type zzzz to see all sections of the book.
