Is there an Android app?

Yes. ScriptFox is on Google Play (listed as "ScriptFox: Voice Teleprompter"); use the "Android app" link in the footer of getscriptfox.com or search Google Play. It's a free download that uses the same account and scripts as the web. Sign in with "Continue with Google" or email and password; the Android app has no "Continue with Apple" button. Like the iPhone app, it is a camera teleprompter: your script sits over the front camera, follows your voice, and records video to the phone. The app follows your account's plan: subscribe on the website (account menu → "Plan & billing") and the phone sees it when you sign in. If a plan was bought inside the app through Google Play, where Pro costs $24.99 a month because Google keeps a share, change or cancel it in your Google Play subscriptions; the website's Plan & billing page shows it.
