Well, turns out despite Google removing the app from the Play store, you can still install and run the app on the latest version of Android. You can find it here on the Internet Archive (I installed ver. 1.2). Just be sure to enable installing apps from whatever browser you used to download the APK.
AFAIK iOS might be SOL. Perhaps someone who does can chime in with a solution (Apple might still be hosting it on the app store for all I know)
