One of the most accessible translating apps currently available on Android, Google Translate does a great job at translating individual words but stumbles often when it comes to sentences, especially longer ones. Still, it remains a highly convenient real-time translator with support for all the major languages of the globe and great features like speech and camera translation, as well as offline support.
Google Translate comes with a polished, streamlined interface that's a pleasure to use. The real-time conversion means that if you don't get a word right, you can quickly try a synonym. But that won't be the case often, because when it comes to word-for-word translations, the app impresses with its accuracy, even when dealing with lesser-known languages. With sentences and paragraphs, the app does get the meaning right most of the time, but the translation isn't always grammatical, or when it is, it's rough. Still, it doesn't get better than this with current free translation tools. Apart from this app's main type-to-translate feature, you'll also like the speak-to-translate option and the ability to translate images taken with the camera, both of which are reasonably accurate. The phrasebook and the ability to handwrite rather than type words are two other nice touches.
If you need a handy translator for travel or work, you won't be disappointed with Google Translate, especially if English is one of the languages you use. Just remember that this app is not intended to replace professional translators.
