You can use Google text-to-speech on an Android phone to help you hear text instead of reading it, and catch grammatical oddities in your own writing.

The app icon on mobile has long been a six-pronged gear — itself similar to the old Android Settings app. Red in color, there’s a white play button at the center.

You can choose a custom icon that you create yourself or if you’re not graphically inclined, you can just specify some text. Android Studio will create an icon for you with that text.
