With your Andjoy, you will soon have the option to invite a friend to train with you once a month for free. You will have a limited number of new invites every month: 1 for Dynamic users and 1 for B-Active Users. The same person cannot be eligible for two invites during a month. It is really easy! Your friend only has to scan the code available in your app to receive the invite. Remember: after the scan your friend has 24 hours to use the code. After that timeframe the code will become invalid.
