The distinguishing feature of the GF Offline Translator is that it can translate 12 languages completely offline and the translation works from any to any language. Despite this it fits in less than 30MB on your device. The translator is designed for natural languages but is based on programming language technology. This is what gives us compact size and lets us control the translation quality. The small size is also what allows us to put everything on the device and to translate offline. Currently we have grammars and dictionaries for English, Bulgarian, Catalan, Chinese, Dutch, Finnish, French, German, Hindi, Italian, Spanish and Swedish. The confidence of the translation is indicated with colours:
- Green: semantic translation, should be correct. But not necessarily the only correct one.
Yellow: syntactic translation, should be grammatically correct. But can be very strange in its interpretation and choice of words.
- Light red: chunk translation, probably incorrect. Builds the translation from small pieces.
- Dark red: word-by-word translation, almost certainly incorrect. Builds the translation word by word.
You can translate both speech and text, as selected in the menu. It works between any pair of the supported languages, which means 132 language pairs at the moment. There are some caveats:
* The app works optimally from English and also from Swedish. From other languages it can be slow and give more red results.
* The dictionaries can have errors, since they are partly extracted automatically.
* Speech input from Hindi and output to Bulgarian don't work currently.
* In Chinese, speech input is Mandarin but output is Cantonese (Yue).
As we are constantly working on the app, expect frequent updates and improvements!
When you tap on a translation you get a screen with alternative translations. Tapping on each of the alternatives gives you grammatical information: an inflection table, if it is a single word, and a syntax tree otherwise.
The app also provides an input method which you can use as an alternative keyboard which allows you to do translation from other applications, for instance while you are entering SMS or e-mail. To activate it go to Settings > Language & input.
This app does not show ads and we promise that it will never do.

The translation is 3-4 times faster. Many dictionaries and grammars are improved both in terms of coverage and in quality. Added translation to/from Catalan.
