Once you have shared your invite link or code, here is what your partner needs to do.
Tap the invite link you shared. This will direct them to download Cupla if they don't have it already, then straight into the connection flow.
If using a code, they can enter it on their Cupla homescreen once the app is installed.
Create their account and complete the onboarding — see How do I set up my account?
Once connected, it may take a minute or two for everything to sync. If you have an active subscription, your partner will not be shown the subscription screen — see How does my subscription work?
If you are having trouble connecting, see How do I sync with my partner? or message our support team from the Cupla app.
