Thr auto-correcting feature and its cache of words are HORRIBLE! If you misspell something (even nonsensical words) the app will either fail to offer a solution, allow the misspelling to publish, or it will offer/change the misspelling to something ver6 uncommon (such as a foreign-sounding proper name or a word most people have not heard of). Finally, if you press/hold a word to ask it to be removed from the app's vocabulary, it will still appear again in the future.
