Does Joyous have an app?

We don't currently have an app. This is so we can make Joyous accessible and easy to use for all participants. By using a web browser participants do not need to download any app to answer questions. This means participants do not require a login to answer questions as the web link is unique to them.
If you want to access Joyous from the home screen of your phone like an app, you can do that by browsing to on your preferred web browser and pinning this to your home screen.
