Description

Hello, it's me, Guileless Bopomofo Keyboard.

I have implemented most features of libchewing (https://chewing.im/), to provide you a choice of Bopomofo software keyboard (aka input method editor).

* Unlike other similar products, though I don't have fuzzy, error-tolerance design, I do still have ability to predict possible phrases by context, and I do remember phrases from your typing history automatically.

* Besides the most common "DaChen", I also provide you "Hsu", "E-Ten 26 keys", and "DaChen CP26" Bopomofo keyboard layouts.

* I also support physical keyboard input with the same layout options, so you can use a consistent Bopomofo experience across virtual and hardware keyboards.

What’s new (5.1.0)

Hi there! Guileless Bopomofo 5.1.0 can now guess your next English word.

* New optional next-word prediction: with English word prediction on, turn it on in General settings, and after each space I suggest the words that most often come next. Tap one and I suggest the word after it. The suggestions come from Simple English Wikipedia, so they suit plain writing more than chatting. Nothing you type is stored.

Thanks for using Guileless Bopomofo!
