It's profoundly annoying when some janky web form or app crashes and you lose a bunch of text, but you're just a few clicks away from stopping that once and for all on your Android device. Type Machine silently backs up every word you type so you can retrieve it later. Does this sound both awesome and worrisome? Well, it's only one of those.
Setting up Type Machine requires you allow the app as an accessibility service, which is how it saves your text.
