I built an Android application based on Wiktionary to show meanings as notifications while reading from other apps like Chrome. The idea is to select the word and then clicking on meaning in the context menu will show the meaning as notification along with option to read the meaning aloud. This reduces the time to switch to a separate app or Google to lookup the meaning. Currently, English, German, French and Polish language are supported.
