I haven’t touched ㄅㄆㄇㄈ since the 70s. While I can recite all the zhuyin phonetics, I can only read them with extreme difficulty. Writing is a lost cause.
However, I’m great at pinyin.
Our local Chinese school instructs children in traditional Chinese characters and zhuyin phonetics. I was using BoPoMo Help, an iOS app with Zhuyin/pinyin conversion tables until I discovered ChineseTools.eu. The design is a bit random but when the kid cannot figure out how to write a word in zhuyin, I use the pinyin to zhuyin converter. It works for words and phrases.
wo xi huan shang zhong wen xue xiao
That’s good enough for me. I can figure out the correct tones on my own.
