I purchased both applications. Both applications are basically the same. They are working good. But the lyrics automatically downloaded from apps are mostly needed to be modified in terms of wording and timing. I would suggest to add customized lyrics features. I uploaded some customized lyrics onto my iPad. It actually works fine. However, when I refresh lyrics, the customized lyrics will be replaced by automatic downloaded lyrics. This is pretty bad. Also there should have options for simplified Chinese and traditional Chinese for lyrics. Currently, only traditional Chinese lyrics are available for downloading. The lyric timing + and - feature can also be enhanced by a lyric editing feature. In this editing mode, One can add/delete/modify sentences and just click a sentence to determine the timing for the sentence. I am waiting for these updates. I am willing to pay more for these new features.
