We've just released Magic Keyboard Free on Google Play.
It takes a dictionary approach rather than a learning approach to predictive text.
We've managed to squeeze millions of word combos into individual language packs for English (UK/US), Spanish, German and French.
As its dictionaries are very comprehensive, it does a pretty awesome job of figuring out what you're trying to say and helping you along as you type.
There's also a Pro version with a few extra features including next-word prediction.
Let us know what you think !
Here are a few screenshots (of Pro)
