The free app Google Translate definitely improves with each new version. Latest new feature: the ability to translate any sentence without being connected. 50 languages are thus available, among the 60 that the application usually has. By default, the English dictionary is installed, but it is possible to add as many as you want, as long as you have enough space on the device.
It takes a little less 200 MB per pack language, which can significantly reduce the space available on your smartphone or tablet. Fortunately, it is possible to easily uninstall a dictionary (except the English dictionary). This offline mode is only available on Android-equipped devices, since there is currently no equivalent on iOS. Finally, last little news: the OCR part of Google Translate now supports the Korean, Japanese and Chinese languages when taking photos.
