As of right now we do not have a dedicate app for either platform, with that said you can save Factbird as a home-screen app:
iPhone
- Open the Factbird application in Safari
- Click the “share” icon (in the bottom center) and select “Add to home screen”. Factbird should now be added as an app on your home screen.
Android
- Open the Factbird application in Google Chrome
- Click the “settings” (upper right corner) and select “Install app”. Factbird should now be added as an app on your home screen.
