Its true, I have been using the canto version quite a lot over the past few months, its a fantastic tool a definitely supports jyutping. My only wish was that the OCR picked up chars like 嘅，嗰，囉，噃。 but its mostly sound characters, everything else is fine and IMO way better than pleco.
Shout out to Mark, its an awesome app!
