This app adds Pinyin romanisation to any Chinese website, but some sites work better than others. Tested on, but not affiliated to, JW.ORG and the Watchtower Online Library (WOL) Chinese pages (app was formerly called PinyinWol i.e. Pinyin WOL). Annotation is performed by your device itself: this app does not send your browsing through any third party. Access to the site you wish to browse is required.
